Measuring Recovery
Success
Most people agree that remov-
ing a listed species from the List of
Endangered and Threatened Wildlife
and Plants due to recovery is a sign of
success. The recent delistings of the
bald eagle, Eggert’s sunflower, and the
species mentioned below are excellent
examples. However, recovery related
delistings currently represent only about
one percent of the species currently
listed. Some people believe that this
means the Endangered Species Act is not
succeeding.
But counting only the number of
recovery related delistings does not give
a true measure of the Act’s success. By
the end of Fiscal Year 2006, the U.S. Fish
and Wildlife Service had the lead for con-
serving 1,269 listed species throughout all
50 states and other lands under U.S. juris-
diction. Given this large number of spe-
cies, and the limited staffing and financial
resources available to the Service for their
recovery, the following statistics provide
another measure of recovery success:
• Three species have been delisted this
year due to recovery: the bald eagle,
Western Great Lakes distinct popula-
tion segment (DPS) of the gray wolf,
and Yellowstone DPS of the grizzly
bear. The Service also proposed
this year to delist two other species
due to recovery: the West Virginia
northern flying squirrel and the
Northern Rocky Mountain DPS of the
gray wolf. We are making significant
progress in recovery-related delistings.
• The most recent data available indi-
cate that 522 listed species are now
stable or improving in status. Forty-
one percent of the species are doing
better since they have gained protec-
tion under the Act.
• Most (1,084) species listed for 2.5
years or longer now have final
recovery plans, 43 species have draft
recovery plans, and 134 species
have recovery plans under revision.
(Another 12 species are exempt from
needing recovery plans.) This means
that 90 percent of listed species now
have a recovery plan in place or do
not require one.
But the story is not all about the num-
bers. There are numerous challenges to
recovering listed species. For example,
a species’ decline often occurs over
decades or even centuries, and the road
to its recovery can be a long one as well.
Addressing threats that have occurred
over long periods typically requires
substantial time and resources. Some
species also face new threats even after
receiving protection under the Act. Many
bird populations, for example, have been
decimated by the introduced West Nile
virus. Other animals and plants face
danger posed by such invasive, non-
native species as the brown tree snake
or the zebra mussel. In the face of these
continuing challenges, we should remind
ourselves that success is measured in the

day-to-day milestones achieved instead of
only the ultimate goal of delisting.
Every time a rare species expands
its range, a breeding pair produces
offspring, a private landowner joins in a
new conservation partnership, a research
project gains vital information about a
species’ life history, or a missing plant
arises from a seed bank is a time worthy
of celebration. All of these, and more,
are cumulative steps that eventually
lead to recovery. And if we can take
action to benefit a listing candidate or
other imperiled species before it needs
Endangered Species Act protection, so
much the better!
From stories about habitat needs for
the Page springsnail (a listing candi-
date), to land purchased by The Nature
Conservancy to protect several at-risk
and listed species, to habitat clean-ups,
and other efforts, the following articles
are wonderful examples of recovery
milestones, both small and large. The
tennis champion Arthur Ashe once said,
“Success is a journey, not a destination.
The doing is often more important than
the outcome.” When it comes to the
conservation and recovery of listed and
imperiled species alike, “the doing” is as
“important as the outcome.”

Creating partnerships that conserve
wildlife as well as economic and social
values can be a challenge. Prior to 2002,
a partnership between the Duckwater
Shoshone Tribe and the U.S. Fish and
Wildlife Service did not exist. But taking
a cooperative approach brought benefits
to the Service’s Nevada Fish and Wildlife
Office (NFWO), the Tribe, numerous
other partners, and a rare fish.
The Duckwater Shoshone Reservation
is an isolated rural reservation that
contains the largest thermal spring in
Nevada. This 3,850-acre (1,560-hectare)
reservation is home to 150 residents
whose principle land use is agriculture.
It also contains a unique hydro-geologic
system that is not typical of most arid cli-
mates. Geothermal activity carries warm
groundwater upward, forming numer-
ous hot springs. The 94° F (34°C) water
of Big Warm Spring is considered the
most important habitat for a threatened
species, the Railroad Valley springfish
(Crenichthys nevadae).
In 2002, the Tribe granted the NFWO’s
Partners for Fish and Wildlife Program
access to the Reservation, and the result
was one of the Service’s most success-
ful Tribal partnerships. In early 2003,
the NFWO signed a Memorandum of
Understanding with the Tribe to begin
recovery actions for the springfish while
preserving the Tribe’s economic, social,
agricultural, and cultural way of life. The
next year, the Tribe received funding
from the Partners for Fish and Wildlife,
Tribal Wildlife Grant, and Tribal Land
Owner Incentive programs totaling
$650,000 to restore Big Spring.
In late 2004, negotiations to decom-
mission a catfish farm and remove all
aquaculture facilities that were negatively
affecting the springfish were complete.
Restoration of the spring system was
designed not only to restore the stream

channels and 68 acres (28 ha) of wet-
land habitat next to the spring, but also
to improve delivery of Tribal irrigation
water by constructing a new irrigation
intake and pipeline delivery system. The
project improved water transport along
the main channel and restored the main
spring source to accommodate appropri-
ate flow rates. In addition to fencing the
newly restored spring and wetland habi-
tat, the partners also restored 45 acres (18
ha) of upland habitat.
The Tribe and the Service met on
September 26, 2007, to sign a Safe
Harbor Agreement, only the second
agreement of this type with a Tribal gov-
ernment, allowing the reintroduction of
the fish while use of the irrigation system
and cattle grazing continues. All of the
partners, including representatives from
the Nevada Department of Wildlife, the
Natural Resources Conservation Service,
the U.S. Geological Survey’s Biological
Resources Water Resources Divisions, the
NFWO, and the Tribe were on hand that
day to celebrate and witness the reintro-
duction of Railroad Valley springfish back
into their historical habitat.
This strong partnership will assist in
the recovery of one of Nevada’s threat-
ened species and, at the same time, help
conserve the Tribe’s traditional way of
life. A quote from Tribal Manager Jerry
Millet earlier this year sums up the recov-
ery effort and the partnership this way:
“There is a great sense of joy and ful-
fillment in my heart seeing the restored
spring with the stream channel flowing
in the location the Great Spirit intended it
to go rather than the man-made direc-
tion. Our goal as a Tribe is to continue
into the future. Improving health in the
land and water for the preservation of
the unique and ancient springfish is part
of the Duckwater Peoples legacy for our
future generations. The success of the
Big Warm Spring Restoration projects
is founded in the collaborative process
and persistent communication involving
the Tribe, the individual tribal business
owner, the Service, Nevada Department
of Wildlife, Bureau of Land Management,
Natural Resources Conservation Service,
Bureau of Indian Affairs and the State
Water Engineer’s Office.”

Rare Bird Nests Are Cause
for Celebration
Scientists and bird lovers are
celebrating a milestone in the recovery of
the Kirtland’s warbler (Dendroica kirtlan-
dii), a highly endangered songbird -- the
discovery in 2007 of three active nests in
Wisconsin and one in Ontario.
The Kirtland’s warbler, whose dis-
tinctive male song can be heard up to
a quarter mile away, nests primarily in
jack pine forests in the northern Lower
Peninsula of Michigan. However, the
species has nested in Michigan’s Upper
Peninsula since 1994 and has been seen
in recent years in Wisconsin and Ontario,
The Wisconsin nests were discovered
by a birder in early summer of 2007.
Recognizing the significance of the dis-
covery, this private citizen contacted and
assisted the U.S. Fish and Wildlife Service
and Wisconsin Department of Natural
Resources in documenting the pres-
ence of Kirtland’s warblers in the state.
To protect the site from disturbance,
the Service is not disclosing its precise
location.
The single Ontario nest was discov-
ered on Canadian Forces Base Petawawa
and was monitored by the Canadian
Wildlife Service and cooperators.
“This development is a testament
to decades of cooperative conserva-
tion among the states of Michigan and
Wisconsin, private landowners, and orga-
nizations such as the Audubon Society,”
says Robyn Thorson, Regional Director
for the U.S. Fish and Wildlife Service’s
Midwest Region. “This discovery proves
that by working together, recovery and
range expansion for an endangered bird
are not only possible, but are happening
as we speak.”
The Wisconsin nests were on land
owned by the Plum Creek Timber
Company. “Discovering the Kirtland’s
warbler nesting in managed forests
in central Wisconsin is exciting and
encouraging, and provides Plum Creek
the opportunity to work further with the
Service on enhancing Kirtland’s warbler
habitat in Wisconsin, as we are planning
to do in Michigan’s Upper Peninsula,”
says Scott Henker, Plum Creek’s senior
resource manager for Wisconsin.
The Kirtland’s warbler was first
described in 1857. Its nesting area
was not known until the first nest was
discovered in Oscoda County, Michigan,
in 1903. Scientists quickly recognized the
species as rare and set aside special areas
to protect it. Nevertheless, the Kirtland’s
warbler population plummeted from 432
singing males in 1951 to only 201 males
in 1971.
Thanks to recovery efforts by federal,
state, and private partners, Kirtland’s
warbler numbers have increased steadily
Ron Austing
8 Endangered Species Bulletin 2007 Highlights
since 1990, reaching 1,707 singing males
in 2007, the highest number since popu-
lation monitoring began. The 2007 count
includes eight males in Wisconsin and
two in Ontario.
Prior to 2007’s historic nesting in
Wisconsin and Ontario, no Kirtland’s
warblers have nested outside Michigan
since nesting occurred in Ontario in the
1940s. In the past two years, several
singing males were found in Wisconsin
and Ontario, prompting optimism that
the species would ultimately nest in
those locations.
“Wisconsin is excited about having its
first Kirtland’s warbler nest, and we con-
gratulate our partners in Michigan who
have worked for so long to strengthen
the Kirtland’s warbler population,”
says former Wisconsin Department of
Natural Resources Secretary Scott Hassett.
“Having this rare bird in Wisconsin is an
honor and underscores our responsibil-
ity to keep providing quality habitat for
wildlife. We look forward to working
with Michigan in the future management
of this rare pine barrens species.”
Now that the Kirtland’s warbler has
been confirmed as a breeding species
in Wisconsin, the Service will look for
opportunities to work with landowners
to encourage management practices that
could benefit the species. An added
advantage of managing habitat for the
Kirtland’s warbler is that it would also
provide benefits for numerous other
bird species, as well as other plants and
animals that depend on similar habitats.
The Canadians have been preparing
for eventual Kirtland’s warbler nest-
ing for several years, having conducted
annual searches for the species, writ-
ten a recovery plan, conducted habitat
inventories, including aerial surveys with
Michigan experts, and participated in
Michigan census work and recovery team
meetings.
In Michigan, the Service and its part-
ners, including the Michigan Department
of Natural Resources, U.S. Forest Service,
and the Michigan National Guard, have
seen success with efforts to recover the
Kirtland’s warbler through restoration and
protection of nesting habitat, control of
the competing brown-headed cowbird,
public information, and the assistance of
organizations like the Michigan Audubon
Society and Kirtland Community College.
“Management partners in Michigan
have worked for decades to restore
the Kirtland’s warbler population,”
says Michigan Department of Natural
Resources Director Rebecca A.
Humphries. “Following this discovery,
we look forward to working with our
partners in Wisconsin to continue the
efforts to conserve this species.”
The Kirtland’s warbler selects nest-
ing sites in stands of jack pine that
are between four and 20 years old.
Historically, frequent natural wildfires
created these stands of young jack pine.
Modern fire suppression programs altered
this natural process, reducing Kirtland’s
warbler habitat.
To mimic the effects of wildfire and
ensure the future of this endangered spe-
cies, state and federal wildlife biologists
and foresters annually manage forests
through a combination of clear cutting,
burning, seeding, and replanting to
promote warbler habitat. Approximately
3,000 acres of jack pine trees are planted
or seeded annually on state and federal
lands in Michigan. These successful
cooperative management efforts have
restored the Kirtland’s warbler through-
out much of its historic nesting range
in Michigan’s Lower Peninsula. The
presence of a healthy and expanding
core population in this area has resulted
in the dispersal and appearance of the
birds in the Upper Peninsula, Canada,
and Wisconsin.

is determined by computer modeling that
indicates how potential floodwater would
move across the landscape, with flexible
flood-tolerant plants placed in the direct
path of water. Large earthen mounds
have been constructed to serve as high
ground refugia for the rabbits to escape
rising water. The reintroduced riparian
brush rabbit population at the refuge is
now the largest population in the wild,
and the restored woodlands at the refuge
are the largest contiguous block of habi-
tat in the rabbit’s range.
In addition to activities on Service
lands, the refuge worked with the
Sacramento Office’s recovery biologists
to create a unique partnership with a
landowner to reintroduce riparian brush
rabbits on a private ranch. The 2,048-
acre (829-ha) ranch is contiguous with
lands being restored by the refuge, and
it includes some of the last available
remaining privately-owned riparian
habitat for the rabbit’s recovery. Through
the continuing efforts of the Service
and its partners, we look forward to the
day when the riparian brush rabbit is
recovered.

Jump Starting a Rabbit’s
Recovery
A secretive mammal that makes
its home in the dense riparian wood-
lands of California’s San Joaquin Valley
is the focus of attention at San Joaquin
River National Wildlife Refuge. Through
intensive habitat restoration and species
reintroduction programs at the refuge,
the highly endangered riparian brush rab-
bit (Sylvilagus bachmani riparius) may
once again flourish in its historical range.
Riparian brush rabbits are endemic
to the valley’s riparian woodlands, but
95 percent of this important habitat has
been lost in California. The last known
wild population of the riparian brush
rabbit was found in the 1990s along
the Stanislaus River in San Joaquin
County. Since 2000, the refuge has
worked with the Endangered Species
Recovery Program at California State
University, Stanislaus; the U.S. Bureau of
Reclamation; recovery biologists with the
Fish and Wildlife Service’s Sacramento
Office; the California Department of
Fish and Game; and others to release
and monitor captive-bred rabbits in the
refuge’s dense riparian woodlands. The
goal is to establish three new self-sustain-
ing populations.
Seldom venturing out in the open, the
rabbits depend on the heavy cover found
in riparian woodlands. Dense thickets
of wild rose and blackberry, covered
by canopies of oak and willow, protect
them from predators such as raptors and
coyotes. Using funds acquired through
a variety of sources, the refuge has been
working with River Partners, Inc.—an
environmental organization—to restore
riparian habitat by planting over 250,000
native plants on 1,000 acres (405 hect-
ares) of refuge land. Once mature, these
riparian plants will provide a safe haven
for the rabbits and a vast assemblage of
other native wildlife. Since riparian areas
are prone to flooding, the planting design

Conserving a Natural
Utah Treasure
The Nature Conservancy recently
announced its purchase of 55 acres (22
hectares) of habitat for rare species in
the St. George area of southwestern
Utah. This purchase is the first step in an
ambitious plan to create a new 800-acre
(325-ha) preserve as an oasis for plants,
animals, and people.
Working with a diverse range of
partners, including the School and
Institutional Trust Lands Administration
(SITLA), the Bureau of Land
Management, the Utah Department of
Transportation (UDOT), the U.S. Fish
and Wildlife Service, and the City of St.
George, The Nature Conservancy has
laid out plans for the creation of the
“White Dome Nature Preserve.” White
Dome is one of the few places where
the gypsum-laced Moenkopi formation is
exposed, and its sparsely vegetated soils
are characterized by a rich biological soil
crust. The preserve will protect habitat
for several at-risk species, including the
zebra-tailed lizard (Callisaurus draco-
noides), the loggerhead shrike (Lanius
ludovicianus), and rare native plants. It
will also harbor some of last remain-
ing populations of the threatened Siler
pincushion cactus (Pediocactus sileri)
and the endangered dwarf bear poppy
(Arctomecon humilis), a plant found only
in Washington County, Utah.
The recent purchase was funded
through private donations from
Conservancy supporters and a Recovery
Land Acquisition grant from the Service.
It marks the first phase of acquisition in
a plan that began in 2005, when SITLA
signed an agreement to make 800 acres
available for sale to the Conservancy and
UDOT to establish a nature preserve with
public access.
Additional land acquisitions in the
South Block by the Conservancy and
UDOT will take place this year and next,
with a goal of piecing together all 800
acres of the White Dome Nature Preserve
within the next few years. The partners
are also creating a long-term manage-
ment plan, including fencing, mainte-
nance, habitat restoration, and research
on the rare plants and their pollinators,
as well as the creation of hiking trails and
signage that educates visitors about the
unique natural features of the preserve.
The Nature Conservancy will manage the
preserve.

“We are facing major growth oppor-
tunities and challenges in our communi-
ties,” says Dennis Drake, a Washington
County Commissioner. “The White
Dome Nature Preserve is a great example
of public and private groups working
together to ensure we protect and cel-
ebrate our natural heritage as we grow.”
The next steps for the White
Dome Nature Preserve include the
Conservancy’s work, funded by a Private
Stewardship Program grant from the
Service, to restore the 55-acre parcel
and the rare species that depend upon
it. Scientists will study the dwarf bear
poppy’s life cycle and pollination pro-
cesses to ensure its long-term viability.
But this effort is bigger than just 800
acres or several rare species. It is about
Utahns coming together to ensure that
Washington County’s future will include
places where people can value and
enjoy the natural wonders in their own
backyard.

New Hope for the
Leon Springs Pupfish
The Leon Springs pupfish
(Cyprinodon bovinus) keeps beating the
odds. In spite of threats from hybrid-
ization, pollution, and habitat loss, it
continues to survive in its desert oasis.
Although usually less than 2 inches
(5 centimeters) in length, they are not
without charisma. During their breed-
ing season, males turn a bright iridescent
blue and aggressively patrol their ter-
ritories with what has been described as
a “puppy like energy” (thus the name
pupfish). The Leon Springs pupfish was
reportedly extinct by the 1950s due to
the destruction of its one known habitat,
Leon Springs in west Texas. Fortunately,
Dr. W.L. Minckley of Arizona State
University rediscovered the fish in 1965 in
Diamond Y Draw, a small nearby spring
system north of Fort Stockton, Texas.
Before the fish was listed as endan-
gered in 1980, extraordinary efforts to
prevent its extinction were long under-
way. In the early 1970s, the Texas Parks
and Wildlife Department (TPWD) and
the Natural Resources Conservation
Service (then called the Soil Conservation
Service) teamed up with a private
landowner to construct an earthen berm
around the source of Diamond Y Spring
to divert potential pollution from nearby
oil and gas production. However, biolo-
gists soon discovered a larger threat to
the pupfish. A genetic analysis showed
that some of the pupfish had hybridized
with sheepshead minnows (Cyprinodon
variegatus), a related but invasive species
native to the Gulf Coast. They presum-
ably were introduced to Diamond Y
Draw by a “bait-bucket” release. In 1976,
some of the remaining genetically pure
Leon Springs pupfish were taken to the
Dexter National Fish Hatchery (now a
National Fish Hatchery and Technology
Center) in Dexter, New Mexico, to
establish a genetic reserve. This action
would later prove vital to preventing
the species’ extinction. (It was among
the first species brought to Dexter as a
refuge population for native fish, but not
the last; the hatchery currently maintains
16 native species.) From 1976 to 1978,
biologists led by Dr. Clark Hubbs of
the University of Texas applied a fish
toxicant at Diamond Y Draw to eliminate
the hybrid population, then successfully
restocked pure Leon Springs pupfish.
In 1994, Dr. Anthony and Alice Echelle
of Oklahoma State University found
that the pupfish in Diamond Y Draw
were again hybridized with sheepshead
minnows. A second round of intensive
recovery efforts took place between
1998 and 2001, involving a large group
of partners and grants from the Fish and
Wildlife Service and TPWD. The hybrid
pupfish once again were eliminated from
Diamond Y Draw using a combination of
chemical and mechanical means before
pure Leon Springs pupfish were repatri-

ated from Dexter. Subsequent genetic
assessments have shown the restoration
efforts succeeded in reducing genetic
contamination to acceptable levels at or
near zero.
As if the threat from hybridiza-
tion were not enough, the habitat is
surrounded by active oil and natural
gas wells. Fortunately, in 1990 The
Nature Conservancy (TNC) purchased
about 1,500 acres (about 600 hectares)
from Mr. M.R. Gonzales and estab-
lished the Diamond Y Spring Preserve.
Immediately, TNC (led by long-time con-
servation scientist John Karges) initiated
on-site stewardship in cooperation with
energy production partners, who granted
funds for the land purchase and modi-
fied their facilities to provide safeguards
against contaminants. A matching grant
in the mid-1990s from an energy pro-
ducer and the National Fish and Wildlife
Foundation provided funds to remove
some oil well pad sites and access roads
that had impeded natural surface water
flow. More recently, TNC was awarded a
Recovery Land Acquisition Grant from the
Fish and Wildlife Service and expanded
Diamond Y Preserve to more than 4,000
acres (over 1,600 hectares).
Using video surveillance, Dr. Murray
Itzkowitz of Lehigh University investigates
the fascinating world of social and breed-
ing behavior of the Leon Springs pupfish.
He has observed that large territorial
males defend areas on rocky shelves in
shallow open water. Intermediate- and
small-sized males act as “satellite breed-
ers” by sneaking in to mate with females
while the territorial male is occupied with
fending off neighbors or courting other
females. Females then enter the male’s
territory to spawn. The female lays a
single egg at a time, but will repeat the
sequence many times before she leaves
the territory for another male or leaves
the breeding shelf altogether. As many
as 25 territorial males can pack into a
30-square-foot (3-square-meter) area.
Territorial males also show complex com-
munication among each other known as
“dear enemy recognition.” This is where
territorial males show less aggression to
familiar neighbors than to strangers.
Other research continues to monitor
genetic integrity, as well as document
genetic diversity in the wild and captive
populations of Leon Springs pupfish.
Maintaining high levels of genetic varia-
tion is important to the species’ recovery
objective of ensuring self-sustaining,
genetically-uncontaminated populations
in Diamond Y Draw.
Behavioral observations in May 2006
revealed a drastically reduced breeding
population with very few territorial or
satellite males. The Fish and Wildlife
Service and TPWD rushed to approve
a recovery grant to recreate the neces-
sary spawning shelves. The open water
needed for spawning was in short supply
due to an increased density of emergent
vegetation. In early 2007, with help from
TNC, Lehigh University students removed
the vegetation by hand and replaced
it with hard tiles. By spring, the fish
responded positively; males reestablished
their territories on the new habitat, and
biologists saw increased numbers of
juvenile fish.
Overshadowing the local threats
from hybridization, pollution, and subtle
habitat changes is the pervasive threat to
groundwater availability. The potential
for loss of spring flows due to regional
groundwater pumping is a constant
danger. Diamond Y Draw is a small
sanctuary within the Chihuahuan Desert.
As an oasis in this dry region, it supports
much more than just the pupfish. It is
home to more than eight rare species,
including the threatened Pecos sunflower
(Helianthus paradoxus), the endangered
Pecos gambusia (Gambusia nobilis),
the endangered Pecos assiminea snail
(Assiminea pecos), two other spring snails
that are listing candidates, and several
other endemic aquatic invertebrates.
Many partners have worked hard over the
past 40 years to ensure the Leon Springs
pupfish survives, but still more work lies
ahead to conserve its fragile ecosystem at
Diamond Y Draw.

Sometimes It’s the Little
Things That Matter
What is good for a rare, rice-sized
crustacean in a Virginia cave system is
proving to be good for one of the south-
ern Appalachian region’s most biologi-
cally diverse and imperiled ecosystems.
The Lee County cave isopod (Lirceus
usdagalun) is a stygobitic (cave-adapted
aquatic) crustacean found on the
surface of rocks under swift flowing,
shallow water in subterranean streams.
Additional specimens are sometimes
flushed from springs during floods. This
creature is known from only two cave
systems and two springs in an area
known as the Cedars, located in central
Lee County, Virginia. Caves, sinkholes,
disappearing streams, and large springs
are common topographical features of
the Cedars, a terrain called karst that
was formed in limestone and dolostone
bedrock. The limestone and poor soils
of this area support an uncommonly
high number of rare plants and animals
and a dominant forest community of oak
and cedar. The watershed of the Cedars
contributes high-quality water to the
Powell River, one of the last free-flowing
stretches of the Tennessee River system
and a river renowned for its rich freshwa-
ter mussel and fish diversity.
The cave systems of the Cedars are
hydrologically complex. Because of
the porous nature of the limestone karst
topography, water flows through the
system quickly, having little time for
pollutants and contaminants to be cap-
tured and metabolized through natural
filtration. As a consequence, seemingly
benign activities can pose a serious
threat to the quality of both ground and
surface waters.
At a glance, threats to water quality
and karst resources in the Cedars would
seem negligible; the landscape is sparsely
developed, covered by a predominant
mix of pasture and forest. However, in
1987, a local sawmill producing a mas-
sive amount of sawdust waste caused
one of Virginia’s most severe cases of
water pollution. An estimated 5.8 mil-
lion cubic feet (165,000 cubic meters) of
sawdust resulted in a massive discharge
of leachate (the liquid produced when
water percolates through any permeable
material) rich in lignins and tannins.
These contaminants seeped into a cave
system known as Thompson Cedar Cave,
haven to one of the two populations of
the Lee County cave isopod known at
the time. Water from the underground
stream resurfaces from a spring and joins
Batie Creek, a tributary of the Powell
Lee County cave isopod

14 Endangered Species Bulletin 2007 Highlights
River. Decomposition of the leach-
ate produced an intense biochemical
demand for the water’s oxygen, exceed-
ing that typically produced by raw
sewage, and it plagued the cave stream
and Batie Creek for more than 15 years,
eliminating nearly all of the aquatic
life. Batie Creek was marked by a
strong sewage odor and the presence of
Sphaerotilus, a filamentous fungus associ-
ated with sewage. Dissolved oxygen
levels at the spring approached zero from
the late 1980s through the early 1990s.
The Service listed the Lee County cave
isopod in 1992 as endangered. In 1998,
Virginia added Batie Creek to the state’s
list of impaired water bodies.
The sobering effect of this disaster
prompted cooperative action to remedy
the problem and protect the fragile karst
ecosystem, and with it the Lee County
cave isopod. The Service, The Nature
Conservancy, Virginia Department of
Conservation and Recreation-Division of
Natural Heritage, Virginia Department
of Environmental Quality, Cave
Conservancy of the Virginias, Virginia
Tech University, Upper Tennessee River
Roundtable, Tennessee Valley Authority,
Virginia Cave Board, and the owner of
the sawmill were among the major part-
ners involved. Between 1998 and 2007,
the partnership coordinated the removal
of approximately 60 percent of the saw-
dust waste from the site, focusing on the
actively decomposing portion generating
most of the toxic leachate. Newly gener-
ated sawdust was taken to an industrial
incinerator in Kingsport, Tennessee, to
produce electric power. Older sawdust
deemed unsuitable for incineration was
used as a soil amendment to accelerate
revegetation of reclaimed surface mines.
The cooperative effort was clearly
successful. By November 2001, the fauna
of Thompson Cedar Cave once again
began to thrive. On February 19, 2002,
staff from the Virginia Division of Natural
Heritage and the Service discovered that
the Lee County cave isopod had returned
to Thompson Cedar Cave. Since then,
the population once thought to be
extirpated has progressed towards recov-
ery. We believe that uncontaminated
upstream tributaries served as refugia
from which Thompson Cedar Cave was
recolonized. Concurrently, dissolved
oxygen levels in the Batie Creek spring
increased dramatically and have stabi-
lized since 2005. As a result, in 2006, the
Virginia Department of Environmental
Quality removed Batie Creek from its list
of impaired waters.
The Lee County cave isopod serves as
a poster child for of the Cedar’s unique
and diverse ecosystem and became
a catalyst for conservation. Because
most of the cave fauna depends on
constant water quality and quantity,
protection efforts have focused on
surface elements as well as the biologi-
cal diversity contained within the caves
and springs. Acquiring lands has been
seen as the most feasible approach for
long-term conservation in this
region. Accordingly, The Nature
Conservancy and Virginia’s
Division of Natural Heritage,
with help from the Service,
secured over 1,000 acres (400
hectares) of prime conservation
lands in the Cedars. These part-
ners plan to acquire additional
lands to expand the Cedars State
Natural Area Preserve. The pre-
serve aims to protect nine signifi-
cant caves and calcareous glades
and woodlands that benefit not
only the Lee County cave isopod
but 31 other rare species.
The Cedars region does not
exist in a vacuum, and land
acquisition alone will not be
enough to protect its unique
biological resources. The cave
streams where Lirceus usdagalun
lives, for example, are supported
to a large extent by surface
streams that sink into cave
systems along the edge of the
Cedars. These streams meander
through mostly inaccessible cave
passage as they flow under the
Cedars and emerge at springs feeding the
Powell River. Protecting these streams
helps not only the subterranean resources
of the Cedars but also the aquatic fauna
of the Powell River.

Cooperative Conservation
for the Page Springsnail
In the legal sense, the term “recov-
ery” applies to species of plants and
animals that are listed as threatened
or endangered under the Endangered
Species Act. However, in practical
application, recovery is just as important
for imperiled species that are headed
towards listing. One such species is the
Page springsnail (Pyrgulopsis morrisoni),
a tiny endemic aquatic snail from central
Arizona. The goal for this species is to
conserve it so that it will not need listing
protection.
The Page springsnail is currently a
candidate for listing due to threats from
habitat modification, groundwater pump-
ing, water contamination, and predation
by exotic species. In 1999, the Fish and
Wildlife Service’s Arizona Ecological
Services Office and the Arizona Game
and Fish Department began cooperative
efforts to conserve this species. The
ultimate goal is to develop a Candidate
Conservation Agreement with Assurances
with the State and other landowners in
order to alleviate threats to the point
where listing is not warranted. (For more
information on these agreements, go to
www.fws.gov/endangered/listing/ccaa.
pdf ). Although a conservation agree-
ment has not been completed, we have
already made significant progress in
conserving the species.
Both agencies have pooled our
resources to study the basic habitat needs
of the species and build a conservation
plan. One result of this effort was the
first piece of published literature dealing
with the Page springsnail’s habitat use.
Additionally, the Arizona Game and Fish
Department fenced important habitats to
protect them from inadvertent trampling
by people or ungulates, and it installed
water gages to monitor any change in
spring water discharge that may result
from groundwater pumping.
Conservation of the Page springsnail
is complicated by the fact that it inhabits
many of the same springs used by two
Arizona Game and Fish Department fish
hatcheries. Working with the hatcher-
ies to balance fish production and snail
conservation has presented challenges,
but it has also presented opportunities to
collaborate on projects that benefit both
goals. Another important milestone is
the development of a draft survey and
monitoring protocol for the springsnail.
Page springsnail

16 Endangered Species Bulletin 2007 Highlights
This is an important step because there
has been no standardized methodology
for sampling springsnails that has been
widely adopted by the conservation
community.
Obviously, we have much more
ground to cover, particularly in the areas
of habitat restoration and reintroduc-
tions of the snail into other sites within
its former range. But we have already
accomplished something very important:
demonstrating the collaborative work-
ing relationship between the Fish and
Wildlife Service and the Arizona Game
and Fish Department.

A Rare Plant Returns to
San Francisco Bay
Suaeda californica, or California
sea-blite, is a rare perennial subshrub
in the goosefoot family. The Fish and
Wildlife Service listed this plant as an
endangered species in 1994. The species
historically grew along high tide lines in
salt marshes of Morro Bay and central
and south San Francisco Bay, often on
salt marshes bordering sand or shell
beach edges.
The species had been absent from San
Francisco Bay since about 1960 when
several years ago two failed attempts
were made to reintroduce it to the San
Francisco Bay’s western shoreline. Seed
dispersal from one of those failed rein-
troduction attempts resulted in successful
spontaneous seedling establishment of
Suaeda californica nearby. Those plants
are now robust and producing abun-
dant seed. In historic East Bay habitat,
though, the species remained absent until
coastal plant ecologist Peter Baye and
I reintroduced it earlier this year near
Emeryville, California, in partnership
with the East Bay Regional Park District
(EBRPD) and with funding through the
Service’s Sacramento Office.
In March 2007, we introduced 14
transplants along the high tide line of
Suaeda californica was reintroduced into this habitat near Emeryville.

County. We backfilled each transplant
site with a mixture of sand and partly
decomposed leaf/macroalgal litter from
nearby drift-lines, then watered with
commercial fertilizer. No significant rain
fell after the transplanting and a week
of warm, dry weather followed. A visit
in April revealed the death of only four
transplants, presumably from insufficient
moisture. The remaining 10 plants,
however, were healthy and thriving.
Moderate to heavy seed production on at
least half the plants is expected later this
year, based on observed flowering.
The recovery needs of Suaeda califor-
nica will be detailed in the recovery plan
for tidal marsh species of northern and
central California, which is being pre-
pared by the Service’s Sacramento Office.
This reintroduction project kicked-off
implementation of the California Sea-blite
(Suaeda californica) Reintroduction Plan,
San Francisco Bay, California, an effort
also funded by the Sacramento Office.
Implementation was designed to use
volunteers from the general public and
non-profit conservation organizations,
including local Audubon and California
Native Plant Society chapters, to conduct
annual monitoring and light maintenance
activities. We expect this demonstration
project to provide scientifically sound
evidence of reintroduction success with
Suaeda californica in San Francisco Bay,
a major milestone on the species’ road to
recovery. Demonstrating the feasibility
and cost-effectiveness of this project may
encourage other restoration and rein-
troduction efforts aimed at declining or
regionally extirpated estuarine plants.
So far, the results are encouraging!

The Division of Habitat and
Resource Conservation (HRC) is often the
first Fish and Wildlife Service program
engaged to prevent the decline of species
so that they will not need Endangered
Species Act protection. But if a species is
listed, HRC is also frequently instrumental
in its conservation. We accomplish this
by ensuring that federal navigation, flood
control, energy, and transportation proj-
ects are designed to minimize adverse
environmental impacts on fish and
wildlife and their habitats. A few of our
recent environmental successes include:
Bringing Back the Platte
Described by early explorers as “a
mile wide and a foot deep,” Nebraska’s
by Dave Stout
Platte River provided a cornucopia of
habitats for species now endangered, like
the whooping crane (Grus americana),
least tern (Sterna antillarum), piping
plover (Charadrius melodus), and pallid
sturgeon (Scaphirhynchus albus). These
creatures and many others occurred
commonly in the Platte River valley until
people began altering the landscape.
Cities diverted river water to quench
the thirst of growing populations, and
farmers took more to provide for an
expanding agricultural economy. By the
early 1980s, more than 70 percent of the
river’s annual flow was being diverted for
human uses. What was once a mile-wide
river with countless unvegetated sandbars
and wet meadows took on the closed
form of an eastern forest. Something
clearly needed to happen before the
open Platte River environment and the
species it supported remained only in
history books.
What began as the Platte River
Management Joint Study evolved into
an agreement among the governors of
Colorado, Nebraska, and Wyoming,
and the Department of the Interior for
the management of endangered species
habitats along the central Platte River
in Nebraska. The agreement ensures
adequate instream flows, enhancement
and restoration of degraded habitats, and
facilitation of water development activi-
ties in the basin.
Tourists throng along the river to
view the seasonal spectacle of skies full

into the local economy. Public attitudes
are changing; people no longer see the
Platte as simply a source of irrigation
water but as a centerpiece of Nebraska’s
cultural and natural heritage.
Restoring an Atlantic Fishery
Our reviews of Federal Energy
Regulatory Commission dam licens-
ing laid the groundwork for restoring
Atlantic salmon and other migratory fish
in Maine’s Penobscot River. The HRC
activities have resulted in an innovative
agreement involving the Service, the state
of Maine, the Penobscot Indian Nation,
the dam’s owner, and several non-gov-
ernmental organizations. The Penobscot
River Restoration Project calls for three
of the dams on the lower part of the
Penobscot watershed to be sold to the
Penobscot River Restoration Trust, which
is made up of non-governmental organi-
zations and the Penobscot Indian Nation.
Two of the dams will be removed,
and the third will be decommissioned
and equipped with a novel fish bypass
system. By recycling generating turbines
from the removed dams to other projects
in the watershed, coupled with other
modifications, Pennsylvania Power and
Light will replace over 90 percent of the
power that would be lost from the dam
removals. The project began in 2005,
with dam removals and other improve-
ments scheduled to occur as early as
2009.
Streamlining Transportation in Ohio
The Ohio Department of
Transportation (DOT) and the Service’s
Ohio Ecological Services Field Office
have worked in recent years to stream-
line the environmental review of fed-
eral transportation projects in Ohio.
Interagency consultations evaluated
potential effects on endangered species
such as the Indiana bat (Myotis sodalis).
In 2006, they agreed on an approach that
eliminates the need for Service review of
transportation projects that both parties
agree are innocuous. Now, the Ohio
DOT coordinates with the Service on
only half as many projects, allowing
both agencies to focus on higher priority
consultations—those more important to
fish and wildlife conservation.

conserve native fish and wildlife and
their habitats. Here are a few examples:
Coaster Brook Trout
The “coaster” brook trout (Salvelinus
fontinalis) spends most of its time in
the nearshore waters of the upper Great
Lakes, migrating into streams to spawn.
Spending part of its life in open waters,
it grows much larger than brook trout
that live entirely in streams. It once was
abundant along the shores and in the
tributaries of Lake Superior. However,
during the past century, populations
were severely depleted and in some
cases eliminated, requiring urgent action
to prevent the need for listing this fish
under the ESA.
To begin the restoration process,
FWMA and its partners developed the
Brook Trout Restoration Plan for Lake
Superior. Guided by the plan, FWMA
works with a variety of interests to

conduct coaster brook trout surveys
and habitat assessments, propagate the
coasters in the National Fish Hatchery
System and state hatcheries, collaborate
with the National Wildlife Refuge System
to develop the Whittlesey Creek National
Wildlife Refuge to protect stream habitat,
and restore habitat by funding fish pas-
sage projects on two Indian reservations.
As a result, coasters are now returning to
historic streams in the upper Great Lakes.
Apache Trout
Native Apache trout (Oncorhynchus
apache) in the southwestern United
States were once on the verge of extinc-
tion and were listed as endangered.
Those populations that remained were
found only on lands of the White
Mountain Apache Tribe in eastern
Arizona.
In cooperation with the tribe and
other interests, FWMA biologists initiated
activities to locate remnant populations,
identify and restore habitat, and work
with national fish hatcheries to reestab-
lish self-sustaining stocks. In all, FWMA
identified genetics of 13 existing popula-
tions of Apache trout, removed non-
native trout from parts or entire reaches
of 14 streams, identified eight natural
barriers that protect existing populations
from non-native trout, constructed 30
barriers in 26 streams to protect new
populations of Apache trout, established
eight new populations in restored habitat,
and restored portions of 21 streams.
As a result, self-sustaining Apache
trout populations now exist in 21 streams
comprising over 140 miles (225 kilome-
ters) of historic habitat. A continuing
success story, the Apache trout has
improved in status enough to be reclas-
sified from endangered to threatened,
and it is on the verge of becoming the
first fish species to be delisted through
recovery.
Niangua Darter
The Niangua darter (Etheostoma
nianguae), a Missouri fish, became a
threatened species in 1985 when res-
ervoir construction blocked upstream
movement and sent it into decline.
Niangua darters live in the riffle-pool
complex of clear upland creeks and small
rivers in the Osage River basin and rely
on continuously flowing streams with
silt-free gravel and rock bottoms. Once
occurring widely in the southern portion
of the Osage River watershed, Niangua
darters are now found only in a few
small, fragmented populations. Another
cause of the population fragmentation
was poorly designed low-water road
crossings that block Niangua darter
movement. These conditions made the
darter increasingly sensitive to environ-
mental extremes (primarily drought), and
the fragmentation has resulted in reduced
or eliminated gene flow and genetic
diversity.
Despite these challenges, the Fish
and Wildlife Service and its partners are
working to protect and increase Niangua
darter populations. To date, 16 projects
and 54 surveys have been completed
within watersheds that support the spe-
cies. Most have resulted from coopera-
tive efforts with the Partners for Fish and
Wildlife Program. Restoration projects
include developing or improving ripar-
ian areas, stabilizing banks along highly
eroded streams, constructing alternative
watering sources for livestock, and modi-
fying or replacing stream crossings within
the darter’s range.
Cooperators across the Nation are
looking to the FWMA program to help
meet their needs for monitoring, coor-
dinating, and implementing fish and
wildlife management and restoration
plans. We will continue to work across
borders of states, Indian reservations,

Two of the Fish and Wildlife
Service’s most popular and effective pro-
grams for voluntary, citizen and commu-
nity-based conservation initiatives are the
Partners for Fish and Wildlife and Coastal
programs. They are a bridge to owners
and managers of non-federal lands for
development of partnerships to benefit
trust species. The approach is simple:
engage willing partners to conserve wild-
life values on their property through the
use of non-regulatory incentives.
The Partners Program is active in all
50 states, the Commonwealth of Puerto
Rico, the U.S. Virgin Islands, and other
trust territories. It is the Service’s premier
program for cooperative conserva-
tion with private landowners, farmers,
ranchers, and resource-based industries.
Between 2003 and 2006, the program
implemented over 500 projects benefiting
threatened and endangered species. The
Coastal Program focuses on large-scale,
long-term collaborative resource plan-
ning and implementation in high-priority
coastal areas.
Through our partnerships, we have
worked to conserve coastal and interior
wetlands, streams and rivers, marshes
and estuaries, and upland grasslands and
forests from coast to coast. As of 2006,
the two programs have:
• restored or enhanced more than
850,000 acres (344,000 hectares) of
coastal and interior wetlands;
• restored or enhanced more than
1.9 million acres (0.8 million ha) of
coastal and interior prairie, shrub,
and forest upland habitat;
• restored or enhanced more than
8,500 miles (13,675 kilometers) of
riparian and instream habitat;

• protected more than 1.2 million acres
(0.5 million ha) of habitat through
conservation easements;
• implemented more than 41,000 land-
owner and cooperative agreements;
and
• leveraged federal tax dollars by
a ratio of at least 4 to1 through
partnerships.
Most of these projects benefit threat-
ened and endangered species as well as
candidates for listing. The following case
studies show how the programs work:
Beaver Cave Project
Cave systems in the Southeast pro-
vide essential habitat for a number of
listed bats, fish, and invertebrates, as
well as candidate species. The Beaver
Cave beetle (Pseudanophthalmus
major) is endemic to the Beaver Cave
system in Harrison County, Kentucky.
Until 2006, it was a candidate for list-
ing under the Endangered Species
Act. The landowner approached the
Partners Program, Kentucky Department
of Fish and Wildlife Resources, and
Natural Resources Conservation Service
to design and implement a conserva-
tion project that removed the need to
list this species. This project would not
have been possible without planning
and collaboration among the landowner,
several Service programs, the Natural
Resources Conservation Service, the Farm
Service Agency, the Kentucky Division of
Conservation, the Kentucky Department
of Fish and Wildlife Resources, the
Kentucky Nature Preserves Commission,
and the Kentucky Division of Forestry.

stream crossing, built in conjunction with
the Farm Service Agency’s Conservation
Reserve Program, to help exclude cattle
from the stream, thereby reducing sedi-
ment and animal waste in the water. The
landowner reorganized his cattle grazing
regime to exclude livestock from Beaver
Creek tributaries on his property. The
Kentucky Division of Conservation then
assisted in installing a feeding area.
The Kentucky Department of Fish and
Wildlife Resources, using federal funds,
provided an additional stream crossing.
The Natural Resources Conservation
Service partially funded the installation
of a gate to protect the cave and cleaned
out a sediment-filled sinkhole.
Most of the animal waste and sedi-
ments from the dairy operation have
been removed and or filtered from the
tributary flowing into Beaver Creek. This
action greatly improved water qual-
ity in the Licking River watershed and
aided in restoration of the listed fanshell
(Cyprogenia stegaria) and clubshell
(Pleurobema clava) mussels.
Pacific Species
In the U.S. Pacific islands, the Coastal
Program works with landowners,
nonprofit groups, government agencies,
and others on habitat protection and
restoration, biological surveys, restoration
research and planning, and environmen-
tal education. Its area of responsibility
includes hundreds of islands distributed
over thousands of square miles of ocean
and covers over 6,500 miles (10.500 km)
of coastline. Pacific island coasts and
nearshore environments include over
90 percent of the U.S. coral reefs and a
range of unique, tropical habitat types
that support many endemic species, hun-
dreds of which are listed as threatened or
endangered.
In support of the Service’s 2005
Seabird Conservation Plan for the Pacific
Region, the Coastal Program played a
central role in funding and coordinating
projects to eradicate non-native rats on
two Hawaii offshore islets, Lehua and
Mokapu. Introduced rats eat a wide
variety of native organisms, including
seabirds, plants, insects, and inter-tidal
invertebrates. Rat eradication reduces
predation and benefits the following
endangered (E), threatened (T), and can-
didate (C) species that currently inhabit
the islets:
• Newell’s shearwater (T) Puffinus
auricularis
• Dark-rumped petrel (E) Pterodroma
phaeopygia sandwichensis
• Peucedanum sandwicense (T)
(Mokapu is designated critical habitat
for this plant species.)
• Band-rumped storm petrel (C)
Oceanodroma castro
Both islets are designated state seabird
sanctuaries, and they support native
plants and invertebrates as well. Mokapu
Island is designated critical habitat for
three listed plants: Brighamia rockii
(E), Tetramolopium rockii (T), and
Peucedanum sandwicense (T), although
only the latter currently grows on the
island. A possible future initiative could
include the reintroduction of these
species.
The Partners and Coastal programs
produce similar accomplishments and
share a common vision of citizen-cen-
tered conservation through partner-
ships. Each program has a unique niche
and focus for carrying out the Nation’s
conservation responsibilities. We will
continue to work with our public and
private partners to assist in reaching
national goals for the conservation of
federal trust species.

The Fish and Wildlife Service has
been studying the effects of contaminants
on fish and wildlife since the agency’s
earliest days, but the Environmental
Contaminants Program did not began to
take form until the 1950s, when increas-
ing awareness of pollution problems
spurred the American public to demand
action. Then, in 1962, Rachel Carson,
a former Service employee, captured
national attention with her landmark
book, Silent Spring, which described the
widespread harmful effects of pesticides
on the environment. Carson’s alarming
message—that the effects of these sub-
stances on wildlife serve as indicators of
what may ultimately jeopardize our own
health—struck a chord with the American
public.
Many believe that Carson’s book
inspired the modern environmental
movement and prompted the develop-

ment of many of the pollution prevention
laws that are in place today. After her
book was published, Congress passed
the National Environmental Policy Act
and pollution prevention laws such
as the Clean Water Act; Clean Air Act;
Federal Insecticide, Fungicide and
Rodenticide Act; Safe Drinking Water
Act; Toxic Substances Control Act; and
the “Superfund” toxic waste cleanup
law also known as the Comprehensive
Environmental Response, Compensation,
and Liability Act.
Today, the Service’s Environmental
Contaminants Program includes contami-
nants specialists stationed at more than
75 locations around the country. These
scientists are on the front lines in the
fight against pollution. They specialize
in detecting toxic chemicals; addressing
their effects; preventing harm to fish,
wildlife, and their habitats; and remov-

ing toxic chemicals and restoring habitat
when prevention is not possible. They
are experts on oil and chemical spills,
pesticides, water quality, hazardous
materials disposal, and other aspects
of pollution biology. Integrated into
all other Service activities, the Service’s
contaminants specialists often work in
partnership with other agencies and orga-
nizations that rely on our expertise.
An example of the program’s work
can be seen in our response to an
oil spill off the U.S. Pacific Northwest
coast that posed a serious threat to
a population of marbled murrelets
(Brachyramphus marmoratus). These
small seabirds live in nearshore marine
environments from California to Alaska
and are the only seabird to nest in
mature coastal forests. Extensive losses
of such habitat led to a decline in
marbled murrelet numbers along the
West Coast, resulting in the 1992 list-
ing of the Washington, Oregon, and
California population as threatened under
the Endangered Species Act.
On July 22, 1991, the Chinese freighter
Tuo Hai hit and sank the Japanese
fishing vessel Tenyo Maru near the
entrance to the Straits of Juan de Fuca,
which separates Washington State and
Vancouver Island, Canada. The Tenyo
Maru released much of the 452,600 gal-
lons (1.7 millions liters) of fuel oil and
diesel aboard, oiling a large swath of the
coasts of Washington and Oregon. The
spill killed over 20,000 sea birds, includ-
ing marbled murrelets.
Under the 1990 Oil Pollution Act
(OPA), natural resource trustees (selected
Federal agencies, States and Tribes) hold
the parties responsible for an oil spill
liable for injury to natural resources and
to restore those injured resources. The
trustees involved in the Tenyo Maru
spill included the Department of the
Interior (represented by the Service’s
Environmental Contaminants Program),
the State of Washington, and the Makah
Tribe. Through the natural resource
damage assessment and restoration
(NRDAR) process under the OPA, the
trustees quantified the natural resource
injuries and, with public input, deter-
mined the appropriate restoration
projects.
Because habitat loss is the greatest
threat to marbled murrelets, most of the
Tenyo Maru restoration projects focused
on habitat protection and enhance-
ment. The trustees used approximately
$4.7 million of the settlement funds to
permanently protect and restore over 900
acres (365 hectares) of coastal forest in
three parcels. These included 220 acres
(90 ha) of rare coastal old growth forest
currently supporting nesting marbled
murrelets, as well as high-quality second
growth forest and younger stands of trees
that will serve as a buffer to the old-
growth stands and eventually grow into
mature forests. One parcel is now a part
of the Willapa National Wildlife Refuge,
while two others are being managed
under a 200-year land use agreement
with the Makah Tribe. All of these areas
are now protected from logging, develop-
ment, and other activities detrimental to
the recovery of marbled murrelets. The
trustees also provided funding to survey
potential marbled murrelet nesting areas,
which through our partners has resulted
in increased protection of another 3,000
acres (1,215 ha) of mature forest habitat
in Washington.
In August 2006, the trustees held a
commemoration to share completion of
the restoration projects with the public
and to inform them of the needs of
Washington and Oregon’s seabirds. Held
on the Makah Reservation, where two
of the newly protected old-growth forest
tracts are located, the ceremony included
tribal traditions, complete with a smoked
salmon feast, tribal dancing, and bless-
ings for the newly protected land.

The National Fish
Hatchery System
by Stuart C. Leon
The Fish and Wildlife Service’s Fisheries Program
is steeped in the conservation traditions of America.
Throughout a history that spans 136 years, the
Fisheries Program has endeavored to respond to the
ever-changing challenges in resource conservation
wrought by constantly evolving societal demands.
This remains true today.
From the earliest beginnings of our
Fisheries Program, the Service’s National
Fish Hatchery System has been a prin-
cipal asset in responding to emerging
conservation challenges. Within the
National Fish Hatchery System, captive
propagation has been, and continues to
be, a valuable and irreplaceable tool in
the management, restoration, and recov-
ery of fish and other aquatic-dependent
species. Used in the right way at the right
time, the System employs captive propa-
gation to restore and replenish aquatic
animal populations in ways that no other
conservation tool can.
Hatcheries complement habitat conser-
vation and restoration programs. Today,

play a significant role in conserving our
Nation’s fish, mussels, aquatic insects and
plants, and amphibians. In doing so, we
also help provide recreational opportuni-
ties to America’s 34 million anglers, who
spend $36 billion annually in pursuit of
America’s favorite pastime.
I am honored to be associated with
the many outstanding professionals that
comprise the Service’s Fisheries Program.
Our workforce is diverse and among the
most technically competent; it includes
ecologists, culturists, geneticists, veteri-
narians, statisticians, disease pathologists,
aquaculture drug researchers, and facility
maintenance experts. They are vested
with the responsibility for recovering spe-
cies listed under the Endangered Species
Act, restoring native aquatic populations,
mitigating for fisheries lost as a result
of federal water projects, and providing
fish to benefit tribes and national wild-
life refuges. The National Fish Hatchery
System works closely with other Service
biologists and with states, tribes, and
the private sector to complement habitat
restoration and other resource manage-
ment strategies for maintaining healthy
ecosystems that support healthy fisheries.
In the following articles, we highlight
a few of the valuable contributions the
National Fish Hatchery System makes
to species recovery. From the saga of
the Lahontan cutthroat trout to the less
visible but equally dramatic struggle for
survival of the Higgins eye pearlymus-
sel, Service fisheries biologists and our
partners are working hard to restore
aquatic wildlife for the benefit of future
generations.

A Living Fossil
Fights for Survival
by Jeff M. Finley and
Craig Springer
Some call the pallid sturgeon (Scaphirhynchus
albus) a living fossil. This large fish arose in the
Cenozoic Era like a dinosaur, then survived the cold
crunch of advancing glaciers and lived to thrive in
the big, muddy rivers of middle North America. Only
recently has the pallid sturgeon experienced changes so
extreme as to threaten its survival. In a century’s time,
habitat destruction, pollution, dams, changes in river
flows, over-fishing, the caviar trade, and hybridization
in the Missouri River basin drove the pallid sturgeon to
the brink of extinction.
and it lives beyond 60 years. But maturity
comes slow; it takes females a decade to
ripen, and even under ideal conditions,
spawning is sporadic and infrequent,
perhaps every other year.
The pallid sturgeon’s life characteris-
tics—a long life and slow growth—may
contribute to its decline. This fish grows
to a size of more than five feet (1.5
meters) and 80 pounds (36 kilograms),

32 Endangered Species Bulletin 2007 Highlights
The Fish and Wildlife Service listed the
pallid sturgeon as an endangered species
in 1990. Since then, natural resource
agencies, governments and citizens from
Louisiana to Montana have joined forces
to recover this ancient fish. The Neosho
National Fish Hatchery in Missouri is one
of six federal and state hatcheries raising
pallid sturgeon for stocking into the
Missouri River.
Only in its fifth year of raising pal-
lid sturgeon, Neosho NFH continues to
increase its production from wild-caught
fish, both by refining culture techniques
and increasing the amount of tank
space. Like most pallid sturgeon raised
at hatcheries, the fish receive either a
colored latex tag or coded wire tag along
with an individually numbered PIT (pas-
sive integrated transponder) tag before
stocking. This helps biologists distinguish
between wild and hatchery-raised pallid
sturgeon, yielding a better understanding
of the species in the wild.
“The Middle Basin Workgroup
determines how many fish we produce;
they set the stocking goal,” says Neosho’s
manager, David Hendrix. “The Service’s
Columbia Fishery Resources Office in
Missouri does the follow-up on survival,
and those tags in the fish tell us where
they came from. The hatcheries are a
management tool to keep the fish from
going extinct.”
In 2004, Neosho’s original sturgeon
building was expanded through a
partnership with the Army Corps of
Engineers. This addition allows the hatch-
ery to spawn and rear an estimated 4,000
pallid sturgeon each year. A building
under construction will allow the facility
to produce another 10,000 fish per year.
The expanded Neosho facility will prove
vital in rearing pallid sturgeon, as will
the Corps-funded renovation of hatcher-
ies like Miles City State Fish Hatchery
in Montana, Gavins Point NFH in South
Dakota, and the Blind Pony State Fish
Hatchery in Missouri, all of which have
expanded to stock pallid sturgeon.
Over 150,000 pallid sturgeon have
been stocked since the fish was listed.
The efforts to raise pallid sturgeon are
the result of cooperation between the
Corps and Service to bring the Corps’s
federal projects into compliance with
the Endangered Species Act. “We are
committed to protection and recovery of
threatened and endangered species like
pallid sturgeon,” says Brigadier General
Gregg Martin, Northwestern Division
Commander.
At the lower end of the species’
natural range, biologists at Natchitoches
NFH in Louisiana have spawned pallid
sturgeon for release in the Mississippi
River. They stocked nearly 12,000 fish in
autumn 2004. No pallid sturgeon have
been stocked there since 2004 because
biologists believe the fish is doing well
enough in the lower basin; these fish
tend to grow faster due to warmer tem-
peratures, thus reaching maturity sooner.
Assistant Hatchery Manager Dr. Jan Dean
continues to advance our understanding
of the fish by creating a larval identifica-
tion series, which allows hatchery and
field biologists to identify pallid stur-
geon in their rapidly changing early-life
forms and distinguish them from the
more common shovelnose sturgeon
(Scaphirhynchus platorynchus). Dean

fish movement in the wild. And move
they do; one of the fish recently caught
by Dean and Paul Hartfield of the
Jackson Office was spawned and tagged
at the Blind Pony State Fish Hatchery,
more than 300 miles (480 kilometers)
away.
Next up the Missouri River from
Neosho is Gavins Point NFH in South
Dakota. This hatchery also was retooled
to handle pallid sturgeon. Hatchery
Manager Herb Bollig and crew have been
spawning pallid sturgeon since the early
1990s. The facility houses the only pallid
sturgeon brood stock in the world: 10
year-classes of 88 families, comprising
thousands of fish. They are still imma-
ture, and Bollig expects a few more years
to pass before they start producing eggs.
With so few wild fish left in the Missouri
River, this brood stock is critical to the
species’ survival. Inspections by Service
biologists at the Fish Health Center in
Bozeman, Montana, lend an extra level
of security, ensuring that the brood stock
remains robust. A new well coming
online should ensure the fish get disease-
free water.
Farther upstream, wild adult pallid
sturgeon are brought to Garrison Dam
NFH in North Dakota, spawned, and
returned to the wild. Some of the wild
adults get a radio transmitter surgically
implanted so management biologists can
learn more about habits and habitats.
Their offspring are eventually released
into the Missouri River as well. Hatchery
Manager Rob Holm says the adults
in the wild are getting old. Some fish
that have been caught over time have
lost weight, underscoring the need for
maintaining a captive brood stock. But
the problem for pallids remains one of
habitat. Captive propagation and milt
(fish sperm) preservation only buy some
time to fix habitat problems, says Holm.
“Our milt cryopreservation repository
captures the existing genetic makeup of
the species,” Holm says. “If the necessary
habitat changes can be made in the next
50 years to facilitate recovery, we want
as genetically a diverse group of sturgeon
as possible to release back into the wild,
and the National Fish Hatchery System
makes this possible.”
Yvette Converse, Assistant Director of
the Bozeman Fish Technology Center in
Montana, agrees on the need to address
habitat: “In the long-term, we don’t
want to be dependent on hatcheries for
recovery, but want to have the habitat
suitable for fish survival in the wild, and
that may take decades. Water manage-
ment may be the biggest obstacle for
pallid sturgeon recovery.” In the mean-
time, the Bozeman Center has expertise
to offer. Physiologist Dr. Molly Webb
has conducted blood assays, using blood
chemistry and hormones to identify an
optimal time to spawn fish. Those assays
could ultimately mean less stress on an
aging and obsolescent population of wild
fish, as well as on captive stocks, and a
greater yield of offspring. Biologist Kevin
Kappenman conducts thermal studies,
looking at egg maturation, hatching and
larval rearing development with chang-
ing temperatures—information useful for
better captive propagation.
Hatchery-raised pallid sturgeon
released into the Missouri River now
have a greater chance to find some of
the shallow-water habitats that are critical
for their survival. The Corps undertook
an aggressive effort in 2004 to create an

estimated 1,200 acres (485 hectares) of
new habitat in the lower reaches of the
Missouri, where habitat loss in the past
has been so great. The Columbia Fishery
Resources Office (FRO) monitors some
of the newly created habitat to see if it
is used by both wild and hatchery-raised
pallid sturgeon. This information will
help guide the designs of future habitat
restorations and determine if a greater
diversity of habitat types is necessary.
In addition to the habitat work, the
Columbia FRO is responsible for pal-
lid sturgeon recovery in some 300
miles of the Missouri River, stretching
from Kansas City to St. Louis. Dr. Tracy
Hill, Columbia’s Project Leader, chairs
the Middle Missouri River Basin Pallid
Sturgeon Workgroup, a multi-stakeholder
forum for coordinating conservation
efforts, and is a member of the Pallid
Sturgeon Recovery Team. The recovery
team is making great strides in scientific
and technological breakthroughs.
Since 1999, Columbia FRO biologists
have managed to capture only 123 pallid
sturgeon in the lower 200 miles (320 km)
of the Missouri River. Seventy-four of
those fish were produced by state and
federal hatcheries. Forty-two fish had no
tags and were thought to be wild fish.
Seven others were of unknown origin but
were suspected to have been stocked.
An important milestone on the road to
recovery occurred in 1999 when biolo-
gists from the Columbia FRO discovered
a freshly hatched larval pallid sturgeon in
the naturally formed Lisbon side chute of
the Big Muddy National Fish and Wildlife
Refuge. This is the only verified case of
natural reproduction within the lower
Missouri River in more than 50 years. The
Lisbon chute, created during the great
flood of 1993, has since been a hot spot
for collecting pallids.
Columbia FRO collected 44 pallid stur-
geon in 2005. However in 2006, it could
collect only 21 fish despite a significant
increase in the sampling effort. The 2006
results are vexing and perplexing, and
they show there is still much to learn. A
myriad of complications face this ancient
and extremely rare fish. Success is incre-
mental, on the river or in a hatchery.

Jay Bigelow holds a male Lahontan
cutthroat trout (Oncorhynchus clarki

and 16 inches (40 centimeters) long, and
admires the sunlight reflecting off the
black-spotted silvery-white flanks. It’s
part of a unique brood stock he’s devel-
oping. Bigelow supervises operations at
the Lahontan National Fish Hatchery in
Gardnerville, Nevada, on the banks of
the Carson River. The hatchery is part
of a larger integrated fisheries com-
plex that includes the Nevada Fishery
Resources Office and Marble Bluff Fish
Passage Facility. These stations coordi-
nate programs to plan and implement
the recovery of the threatened Lahontan
cutthroat trout.
One of 13 cutthroat trout subspecies
in the American West, this fish evolved
in ancient Lake Lahontan, which at its
maximum size inundated about 8,600
square miles (22,300 sq. kilometers) of
northwestern Nevada and parts of sur-
rounding states. As glaciers retreated at
the end of the last ice age, an attendant
climate change dried the basin, and
Lake Lahontan receded to form the few
isolated lakes found today. With gradual
climate change, the Lahontan cutthroat
trout developed into a fish able to with-
stand environmental extremes that today
readily kill other fish species. Two forms
of the Lahontan cutthroat arose: one
accustomed to life in flowing waters; the
other, a lake-dweller.
Pyramid and Walker lakes at the
bottom of the present-day basin held
native Lahontan cutthroat trout. These are
terminal lakes, meaning that water leaves
them only by evaporation. As a result,
their mineral content is extremely high.

In its lake habitats, Lahontan
cutthroat trout can grow to larger
than 60 pounds.
36 Endangered Species Bulletin 2007 Highlights
Lahontan cutthroat trout not only tolerate
this condition, they evolved to thrive
in it. These lake-form fish had other
remarkable adaptations. The numbers
of cartilaginous filaments or gill rakers
inside their throat are exceedingly high,
indicating a habit of feeding on micro-
scopic animals. The fish also has a diges-
tive track for preying on fish. For eons
it was atop the food chain, wreaking
havoc on fish like the cui-ui (Chasmistes
cujus) and tui chub (Gila bicolor), and
most likely cannibalizing its own. In its
lake habitats, the Lahontan cutthroat trout
grew to phenomenal size. The largest
known specimen tipped the scale at 62
pounds (28 kilograms) in 1916.
In 1905, the Bureau of Reclamation’s
first water development project, the
Newlands Project, altered water avail-
ability and flow to Lahontan cutthroat
trout. Pyramid and Walker lake levels
dropped as farmers diverted water to
irrigate fields, and fish lost their access
from Pyramid Lake to their spawning
gravels in the Truckee River. Due to
a lack of available spawning habitat,
Pyramid Lake was devoid of the trout
by 1939. Although reduced numbers of
river-dwelling Lahontan cutthroat trout
remained, the native strain of lake-
dwelling trout that carried the genes for
tremendous growth in the face of harsh
conditions appeared to be extinct.
At some point in the past, trout were
transferred from Pyramid Lake into a
small fishless stream, Morrison Creek,
on Pilot Peak in Utah, an event that
proved priceless for conservation. When
and by whom the transfer was made is
unknown. Fast forward to the 1970s. As
a precaution against extinction, Bryce
Nelson of the Utah Department of
Natural Resources later transferred some
of the Morrison Creek fish to nearby
fishless Bettridge Creek on Bureau of
Land Management lands. Genetic stud-
ies commissioned by Lisa Heki, Project
Leader of the integrated Lahontan NFH
Complex, and conducted by Dr. Mary
Peacock, University of Nevada-Reno,
found that the fish surviving in the Utah
streams are pure representatives of the
original lake-dwelling form of Lahontan
cutthroat trout.
Through Heki’s 12 years of recov-
ery work, the Lahontan National Fish
Hatchery has moved from a focus on a
short-term put-and-take sport fishery to
a facility centered on the recovery of a
native threatened species, but one with
even greater sport fishing qualities. Heki
is optimistic. “Yes, it can be done, and
quicker than people believe—if there is
cooperation,” she says. “Twenty years
down the road, we could have 20- to
30-pound cutthroat trout running the
river right through downtown Reno.”
Building brood stocks from wild fish
takes time. Bigelow and crew carefully
manage the brood stock to maintain
a robust line and genetic integrity. To
“keep the wild in the fish,” fertilized eggs
from Morrison Creek trout are brought to
the hatchery and infused into the brood
stock. The hatchery complex has a
partner in Steve Doudy, a conservation-
minded citizen who owns the land over
which Morrison Creek flows.
In 2001 the hatchery achieved suc-
cess in its hatching efforts, and in 2004
the hatchery placed 13,197 fish into
Pyramid Lake. There they are expected
to significantly contribute to the recre-
ational fishery managed by the Paiute
Indian tribe.
The hatchery continues to meet rigor-
ous demands for fish health. Some of the
fish will be stocked in California’s Fallen
Leaf Lake and perhaps in Lake Tahoe.
The fish culture expertise will be applied
as eggs are incubated at the Marble Bluff
Fish Passage Facility, located near the
terminus of the Truckee River above
Pyramid Lake. To imprint the young fish
on the river water and get the adults
to swim back through the passage into
the Truckee to spawn, the eggs will be
incubated in Truckee River water. It will
be a few years before success can be
measured, but now this unique fish has a
real chance for recovery.

Hatcheries Are for
More Than Fish
by Richard Shelton
Native mussels may be the most
endangered aquatic animals. Here in
Arkansas, they were once found in great
abundance within many streams. But
pollution, over-harvest, impoundments,
and dredging changed the character of
streams and took a toll on many aquatic
organisms.
Native Americans found mussels a
dependable food source, and they used
the shells for tools, art, and jewelry. From
the 1800s until the 1940s, mussel shells
were used extensively for buttons until
the advent of Bakelite plastics. “Mussel
shelling” has seen a resurgence in recent
years; they have become valuable not
only for their own freshwater pearls but
for shipment to Asia for use as “seed” for
more valuable saltwater oyster pearls.
Mussels occupy a valuable ecological
niche; they provide a food source for
fish and mammals and provide a natural
filtering mechanism, which also makes
them excellent biological indicators of
aquatic health.
Mussels have a complex life cycle.
They begin as larvae, or glochidia as they
are called. The glochidia must attach to
specific host fish species, upon which
they transform and grow until dropping
onto the stream bottom and maturing
into adults. Each species of mussel has a
specific fish host that it must find when
it is ready to spawn. Some mussels have
developed ingenuous adaptations to lure
fish close enough for implantation, such
as appendages that resemble worms.
When pollutants or other processes cause
a decline in either the mussel population
or the fish host species, the reproductive
cycle is broken and entire mussel com-
munities may collapse.
Perhaps the most insidious threat to all
freshwater mussels is the invasive zebra

mussel (Dreissena polymorpha). A native
of Europe, the zebra mussel was acci-
dentally introduced into the Great Lakes
in the 1980s when foreign ships dumped
bilge water containing zebra mussel
larvae. This thumbnail-sized invader has
a propensity to attach in huge masses
to any hard object, including the hard
shells of other mussels. Zebra mussels
can cover and even smother beds of
native mussels. They have already spread
throughout much of the Mississippi River
drainage by attaching to the bottom of
boats and barges or entering the cooling
system of boat motors. Without natural
predators, it is a virtual certainty that
this pest will eventually inhabit most
North American streams, with predict-
ably devastating effects on native mussel
populations.
To address the threats to native mussel
species, the Mammoth Spring National
Fish Hatchery has dedicated its facilities
and expertise to helping endangered
mussels for the past decade. Its biolo-
gists have teamed with Arkansas State
University to learn the basic life history
of the animals, learning the techniques
needed to grow and spawn them. Part of
that effort is to discover the specific host-
fish species. These fish are often obscure
or rare, and much remains to be learned
about them as well.
Due to the threats posed by a zebra
mussel invasion of southern waters,
Mammoth Spring biologists investigated
the utility of holding native mussels
in ponds, essentially providing refugia
against loss of wild populations. Over
two years, about 850 mussels of 25 spe-
cies from the White River system were
held while their growth and survival
were monitored. Juveniles were reared
for release into native habitats to restore
depleted populations. As early as 1995,
Mammoth Spring staff propagated native
mussels and reared them to the juvenile
stage for release into Leading Creek.
During these efforts, important life
history traits continue to be discovered.
We now know more about propagating
the endangered speckled pocketbook
(Lampsilis streckeri), the threatened
Arkansas fatmucket (Lampsilis powellii),
and the threatened Ouachita creekshell
(Viliosa arkansasensis) for reintroduction.
Mammoth Spring biologists are investigat-
ing the life histories of two additional
endangered mussels, the pink mucket
(Lampsilis abrupta) and fat pocketbook
(Potamilus capax), both of which could
be affected by future highway projects
in Arkansas. The Arkansas Highway and
Transportation Department is an impor-
tant partner with the Fish and Wildlife
Service in conserving these native
mussels.
The breadth of projects undertaken
and the lessons learned show that fish
hatcheries are for more than fish. In an
ecological sense, the ties that bind fish
and mussel are strong, and conserving
mussels benefits fish and other animals.

The Texas Blind
Salamander
by Craig Springer
Pallid and spindly, eyeless and other-worldly, Texas
blind salamanders (Typhlomolge rathbuni) make their
living in the watery labyrinth of the Edwards Aquifer
in central Texas. Top predators, they eat crustaceans,
snails, and probably each other in the wild. Their entire
lives are spent in water and in the darkness of caves.
They have no reason to come into daylight, as indi-
cated by the vestiges of eyes (which begin as tiny black
dots and quickly disappear early in life) and by the
lack of pigment. It was by accident that they were even
discovered and by happenstance that the discoverer
launched their conservation.

its good water influenced renowned U.S.
Fish Commission ichthyologist Barton
Evermann to locate the hatchery there.
He wrote, “The river has its rise in a
number of springs at the foot of a lime-
stone ledge or hill just above town. All
these springs together form a large, deep
stream, from the bottom of which, near
the upper end, wells up the principal
spring.” Four years later, Evermann facili-
tated the collection and description of the
eyeless salamanders from the springs that
had so impressed him.
The facility, today known as the
San Marcos National Fish Hatchery and
Technology Center, works with the
Service’s Austin Ecological Services Field
Office to recover the rare amphibians,
arguably among the country’s rarest and
most unusual animals.
Fish biologist Joe Fries guides con-
servation initiatives for the species at
the Technology Center, maintaining
tanks and keeping salamanders collected
from different sites separate to ensure
genetic diversity. Almost anything learned
through the work is new information, he
says.
“We know they are highly endemic
and rare, but just how rare we can’t say
for sure,” says Fries. “They are hard to
research because they are so hard to get
to; that’s why we’re looking into their
life-history in captivity.”
Keeping salamanders at the facil-
ity serves a dual purpose. Maintaining
captive populations allows biologists to
gain important information about the
species—its growth rates, eating habits,
temperature tolerances, and reproduc-
tive ecology. The facility also serves as
a refuge. Captive animals are a back-up
population in the event of a dramatic loss
in the wild. And that speaks to threats;
what goes into the Edwards Aquifer goes
through Texas blind salamanders.
The region is known for its karst
topography. Karst is a three-dimensional
landscape shaped by the dissolution
of soluble carbonate bedrock, such as
limestone, that is highly fractured and
contains subsurface drainage systems,
often including caves. Aquifers formed
in karst topography are usually quick
to recharge from surface drainage. A
diesel spill, or other contaminants such
as run-off of agricultural chemicals,
within the recharge zone of the Edwards
Aquifer could cause serious harm to the
water quality, and thus to Texas blind
salamanders.
Water quality aside, there is the issue
of water quantity. As the human popula-
tion grows, so does its demand for water.
Reducing the amount of water in the
aquifer could reduce available habitat.
The threats of pollution and aquifer
overpumping were what led to listing the
species in 1967 as endangered.
Although salamanders at the
Technology Center have laid eggs and
produced offspring, the survivors have
yet to reproduce. Eggs from the first-
generation of captive salamanders have
disappeared and were probably cannibal-
ized. In his studies, Fries is striving to
fill in knowledge gaps, closely following
the species to bring about its recovery in
anticipation of its eventual delisting.
A lifetime naturalist, Barton
Evermann served as Chief in Charge
of the Division of Scientific Inquiry

Hatchery Breeds
Wyoming’s Rarest Toad
by Craig Springer
Detroit. Toledo. Cincinnati. New
York City. Saratoga. They all hold captive
populations of an endangered amphib-
ian, the Wyoming toad (Bufo hemiophrys
baxteri). Small captive populations of the
rare toad live in eight city zoos across the
country, all participating in the American
Zoo and Aquarium Association’s Species
Survival Plan (SSP), a systematic arrange-
ment to keep the toad from going
extinct. But it’s near a small Wyoming
town where the Saratoga National Fish
Hatchery has one of the largest captive
populations, which should contribute in
large measure to the toad’s recovery.
The Wyoming toad’s natural range is
within roughly a 30-mile (48-kilometer)
radius of Laramie. Following a population
crash, the toad was listed as endangered,
and most of its habitat is now protected
as part of the Mortenson Lake National
Wildlife Refuge. As is the case with most
listed species, the major factor behind
the decline was habitat loss. Irrigation
out-competed wetlands for water, and
matters were made worse by continued
drought. Sensitivity to herbicides was
a factor, too. Then there’s the chytrid
fungus (Batrachochytridium dendroba-
tidis). Chytrid infections seem to play a
large role in suppressing the animal, says
David Paddock, the lead toad biologist at
Saratoga NFH.
As part of the recovery program,
Wyoming toads were brought to the
Saratoga NFH for propagation. Captive
breeding began in earnest in 1999.
Since that time, an average of 6,863
Wyoming toads have been released each
year. Between 1999 and 2003, Saratoga
produced an average of 55 percent of
the toads released to face the rigors
of the wild in the Laramie basin. Just
last year, tadpoles from Saratoga were
released onto two new private land sites
covered under Safe Harbor Agreements,
a wonderful arrangement made possible
by the Service’s Cheyenne Ecological
Services Office and the Laramie Rivers
Conservation District.
The Saratoga facility also produces
trout for restoration into the wild.
Paddock is a fish biologist by training
and a toad biologist by necessity. But
he says animal husbandry is much the
same, whether for trout or amphibians.
He keeps toads at the hatchery carefully
isolated from the fishes in their own
environment, and he adheres to strict
protocols to prevent the spread of chytrid
fungus or other disease-causing patho-
gens. Toads with chytrid are cared for
with antifungal treatments.
He says it’s easier to get the toads
to breed than one might expect. Of the
150 adult toads kept on station, breed-

ing pairs are carefully selected from
a studbook—one used by all the par-
ticipating zoos in the SSP—to maintain
genetic integrity. He gets it done, he says
jokingly, “with a little wining and dining.”
Selected adults are paired off in tanks in
two inches (five centimeters) of water
filled with artificial plants, then injected
with hormones to induce production
of eggs and sperm. He leaves them to
their desires while recorded toad calls
play in the background to simulate
the competitive breeding that exists in
nature. And Wyoming toads are fecund.
Three days later, some of the 2,000
eggs start hatching, and in a matter of
days to a few short weeks tadpoles and
toadlets are forming. They also quickly
become crowded, and therein lies part
of the reason the Saratoga Hatchery is so
important to the toad’s recovery. The par-
ticipating zoos have such limited space
that breedings are few—maybe four a
year. Because of its space and expertise,
Saratoga is able to perform many more
breedings each year, 20 or more, and
that means more toads released into their
native habitat. That expertise, Paddock is
quick to note, isn’t all in husbandry. The
physical plant is irreplaceable. The hatch-
ery is plumbed with a good supply of
water, and maintenance man Pat Malone
takes care of it all.
Most of the toads are released in
the tadpole stage, and about six weeks
after eggs are laid they enter the toadlet
stage. Toadlets are released in August,
giving them a chance to acclimate to the
wild and find quarters in small-mam-
mal burrows before the cold Wyoming
winter arrives.
Paddock and others at the hatchery
continue to improve the toad husbandry
techniques. The 2006 breeding season
saw a 17.8 percent increase in its hatch
rate over previous years. It’s probably
attributed to how they treated their
brood stock toads over the winter.
Paddock held select pairs of toads in
colder temperatures over winter to more
closely simulate the harsh weather they
face in the wild. That exposure during
hibernation may have cued something
physiologically to make the animals
more fecund. So, another refrigerated
hibernation unit is on the way to the
hatchery, and Paddock expects the
toads to show even greater reproductive
success in 2007.
The Saratoga Hatchery has a long
and productive history. Established in
1911, it created the first brood stock of
the threatened greenback cutthroat trout
(Oncorhynchus clarki stomias). Now,
Saratoga is the first facility in the National
Fish Hatchery System to hatch and raise
an endangered toad. It’s making its mark;
after the hatchery put toads into the wild,
there is evidence of natural reproduction
on Arapaho National Wildlife Refuge, a
vital step on the road to recovery.

A New Approach for
Monitoring Multiple
Species
The Sonoran Desert Conservation
Plan (SDCP) is an innovative and
comprehensive strategy to preserve the
biological diversity and cultural heritage
of Pima County, Arizona, in response to
unprecedented human population growth
and its associated impacts (see www.
pima.gov/sdcp). Pima County is now
implementing the SDCP through a host of
conservation measures, including devel-
opment set-asides, purchase and lease of
open space, and habitat restoration. The
Pima County Multi-species Conservation
Plan (MSCP) is an important component
of the SDCP. It will ensure that develop-
ment-related activities comply with the
Endangered Species Act (ESA) through
issuance of a section 10 “incidental take”
permit from the U.S. Fish and Wildlife
Service. The Pima County MSCP cur-
rently includes coverage for 36 “Priority
Vulnerable Species” (PVS): 4 species of
plants, 8 mammals, 8 birds, 7 reptiles,
6 fishes, 2 amphibians, and 1 inverte-
brate. To complete the MSCP package,
Pima County is developing a monitoring
program.
Monitoring for Conservation
Ecological monitoring is one of the
most challenging endeavors in ecol-
ogy and natural resource management.
Single-species monitoring can be expen-
sive, and the number and breadth of
species covered under most MSCPs, like
that being developed for Pima County,
creates a financial burden if the goal
is to effectively track populations over
time. While some efficiency can be
gained by monitoring multiple species
using similar field methods and employ-
ing prudent sampling design elements
(see Elzinga et al. 2001), costs can still
remain prohibitive, particularly because
many vertebrate species covered under
MSCP plans are rare and secretive. This
expense can lead to increased program
costs because of the extra level of survey
work needed to estimate population
and/or occupancy for these rare spe-
cies. In addition to cost, monitoring for
dozens of species has been problematic
from the perspective of adaptive manage-
ment, in part because causes of observed

population changes are often unknown
or ambiguous or, in the case of migratory
species, the result of conditions outside
the control of a local manager. The high
cost and management challenges posed
by monitoring multiple species require
a new approach for MSCP monitoring in
Pima County.
A major focus of the approach being
advocated for the Pima County MSCP
involves monitoring a broad suite of
biotic and abiotic indicators (environ-
mental characteristics) that are known to
influence biodiversity over large land-
scapes. Indicators include climate (tem-
perature and precipitation), vegetation
structure and condition, water quality and
quantity, and landscape patterns (e.g.,
land use and fragmentation). Monitoring
a select group of these indicators, along
with targeted monitoring of threatened
and endangered species, will form the
foundation of the Pima County program.
Thanks in part to an ESA-section 6
grant from the Service, a design team
from Pima County and the University of
Arizona will identify the biotic and abi-
otic indicators that hold the most promise
for inclusion into the program. By taking
an integrated approach to monitoring—as
opposed to a species-level approach—
Pima County should have the best
chances of detecting and responding to
environmental changes resulting from a
broad range of stressors at many ecologi-
cal scales. When compared to monitor-
ing all proposed PVS, this approach will
also lead to greater cost efficiency.
A key design component of this
monitoring approach will be to link the
habitat needs of PVS to those broader
indicators of environmental conditions
through development of conceptual
models. These linkages are critical to
ensure the Service’s acceptance of the
monitoring plan.
We plan to explore monitoring part-
nerships with a host of entities in Pima
County that are either actively monitor-
ing or engaged in the planning process.
We are fortunate to have a number of
outstanding partners for this endeavor,

In addition, monitoring both on and

better gauging compliance with the terms
of the ESA-section 10 permit.

National wildlife refuges in

Their contributions focus on restoring
and protecting vital wildlife habitats.

refuges:
Least Bell’s Vireo

in the Valley was in 1919, and by the
1940s the bird was no longer detected
there at all. This made the 2005 nesting
an historic event. The return of a bird
long absent from the Valley symbolized
the importance of riparian woodland
restoration on the refuge. Vireos nested
again in 2006 and 2007. Known to
exhibit high faithfulness to breeding sites
(philopatry), the birds have nested in
arroyo willows near the previous years’
nest sites. Refuge biologists are care-
fully monitoring the nests and hope that
young birds hatched on the refuge will
return to breed.
Valley Elderberry Longhorn Beetle
The valley elderberry longhorn beetle
(Desmocerus californicus dimorphus)
was once thought to be restricted to a
mere three river drainages in California.
After the Service listed this species as
endangered, it protected and restored a
substantial amount riparian habitat, espe-
cially at the Sacramento NWR Complex.
As of June 2007, the refuge, The Nature
Conservancy, and River Partners (an
organization founded by conservation-
minded farmers) had planted 117,235
blue elderberry (Sambucus mexicana)
bushes, which are vital to the beetle, on
4,814 acres (1,948 hectares) of riparian
and floodplain habitat. This effort, along
with the work of other partners and the
discovery of additional beetle popula-
tions, may soon lead to delisting the
beetle as a recovered species.
A Mouse Relocated
The salt marsh harvest mouse
(Reithrodontomys raviventris) is an
endangered species endemic to pick-
leweed-dominated habitat along the
fringes of tidal marshes of the San
Francisco Bay estuary. Over 80 percent
of the marsh habitat around the estu-
ary has been modified or destroyed.
Protection of the remaining habitat,
along with salt marsh restoration and
enhancement, are vital to the species’
recovery. The efforts of many public
and private groups in the Bay area have
led to noticeable gains in habitat conser-
vation for the mouse and other wildlife.
One step in the mouse’s road to
recovery involved a parcel on the Don
Edwards San Francisco Bay NWR.
Refuge specialists converted acquired
agricultural land into salt marsh wetlands
covered with pickleweed. With the
habitat restored, they translocated salt
marsh harvest mice from an off-refuge
parcel that was being lost to develop-
ment. After two years, the numbers of
mice are remarkable, but some things just
don’t show up in the cold hard numbers,
such as the several male-female pairs
of harvest mice captured in the same
trap. (Without going into the scandalous
details, let’s just say that the biologists
nicknamed trap D-22 the “Honeymoon
Suite.”) The efforts of the refuge biolo-
gists and, yes, the mice appear to be
successful. Not only are the translocated
mice doing well, but the restored habitats
are also being recolonized naturally,
bringing recovery of the salt marsh har-
vest mouse another step closer.
Vernal Pools
Many refuges within the San Luis, San
Francisco Bay, and Sacramento NWR
complexes contain special wetlands
called vernal pools. These are seasonally
flooded depressions in impermeable soils
that hold winter rainwater until evapora-
tion. The pools are home to specialized
plants and animals adapted to this wet/
dry regime. As the pools dry over sum-
mer months, concentric rings of colorful
flowers grow in halos around the water
edges. These self-contained ecosys-
tems are home to several listed species,
including California tiger salamanders
(Ambystoma californiense), vernal pool
tadpole shrimp (Lepidurus packardi),
vernal pool fairy shrimp (Branchinecta
lynchi), and plants such as the palmate-
bracted bird’s-beak (Cordylantus palma-
tus). In addition to restoring the natural
hydrology of the pools, Refuge staff

prescribed fire, carefully-monitored herbi-
cide applications, and selective grazing

Light-footed Clapper Rail
Much of the recent success towards
the recovery of the endangered light-
footed clapper rail (Rallus longirostris
levipes) is due to determined efforts
of the San Diego Bay NWR, Carlsbad
Fish and Wildlife Office, California
Department of Fish and Game, U.S. Navy,
Chula Vista Nature Center, SeaWorld-San
Diego, San Diego Wild Animal Park,
Port of San Diego, local scientists, and
volunteers. Although the species is not
out of danger, the rail’s population has
risen from just 142 pairs in 14 coastal
marshes in southern California in 1984 to
approximately 408 pairs in 18 marshes.
The development of a captive breeding
program and translocation of birds to
marshes along the southern California
coastline were significant steps in the
rail’s restoration. The San Diego Bay
NWR is pivotal to this program by pro-
viding a location in which young fledg-
lings are acclimated before translocation
to receptor marshes.

Russia’s own healthy economy. Wildlife

In a world where many animals are
under siege, the Amur tiger (Panthera
tigris altaica) – better known in the West
as the Siberian tiger – offers an encourag-
ing message: the population of this huge
cat is showing signs of recovery.
During the past 100 years, the Amur
tiger population of the Russian Far East
was decimated by forest destruction,
trophy hunting, and poaching for tiger
body parts to use in traditional Asian
medicine. By the 1940s, its numbers had
dwindled to an estimated 50 tigers. But
thanks in part to $611,131 in U.S. Fish
and Wildlife Service grants that, com-
bined with partner donations and in-kind
contributions, push the total to more than
$1 million, the big, distinctive cats appear
to be rebounding in Russia.
Recent surveys indicate that 331 to 370
adult tigers and 100 young are living in
the Russian Far East, which is home to 95
percent of all Amur tigers in the world.
Service wildlife biologist Fred Bagley,
long associated with Amur tiger conser-
vation efforts, says a spike in tiger poach-
ing in the early 1990s was subsequently
met by a Russian government crackdown,
and the intensified anti-poaching efforts
have paid off.
Some estimates place the global tiger
population in the 3,900 to 5,100 range,
down from perhaps 100,000 more than
100 years ago. The Amur tiger is one
of five remaining tiger subspecies in the
world. Eight subspecies once roamed
the earth, but three became extinct in the
20th century. While most Amur tigers
live today in the Russian Far East, a much
smaller number are known to inhabit
China, and a few may occur in North
Korea.
The demand for tiger parts for use in
traditional Asian medicine has played
a major role in the decline of the Amur
tiger population. Despite medical
evidence to the contrary, belief persists
that tiger parts can curb ailments ranging
from impotence to arthritis, skin disease,
fever, and more.
During the last period of heightened
poaching, Russian conservation workers
estimated that as many as 60 tigers were
killed each year. But the Amur tigers’
situation has shown marked improve-
ment. Local government in the Russian
Far East, says Bagley, is committed to
helping rescue the tigers, and the Service
has remained a firm partner in the effort.
Service grants have helped pay for
vehicles, uniforms, fuel, and even salaries
for Russian game wardens who have
had success in deterring poachers. It’s a
relationship that has had positive results.
“It’s hard to find another place in the
world where tigers are doing as well,”
Bagley says.
Left alone in the wild, the tigers do
well. Amur tigers breed easily, and even
though the number of young in the
current decade has given cause for some
concern, the number of cubs born to
each litter has increased slightly, granting
some stability to the gradual population
increase.
Amur tigers, which can weigh up to
600 pounds (270 kilograms) at maturity,
are loners that travel enormous distances

Translocation and Disease
Monitoring of Wild Laysan
Ducks
The Laysan duck (Anas laysa-
nensis), also known as the Laysan teal
because of its small size, is a critically
endangered waterfowl species that once
occurred widely across the Hawaiian
Archipelago. For the past 150 years,
however, it was restricted to a single
population on Laysan, a 4-square-kilo-
meter (1.5-square-mile) island with a
hypersaline shallow lake. Laysan is part
of the Hawaiian Islands National Wildlife
Refuge in Papahanaumokuakea Marine
National Monument.
Evidence suggests that the Laysan
duck’s disappearance from the rest of
the Hawaiian Islands was partly due to
the introduction of predatory non-native
rats during human colonization of the
Hawaiian Islands about 1,000 years ago.
Rats never became established on Laysan
Island. However, in the 1800s, people
who came to Laysan to harvest guano
introduced rabbits that largely denuded
the island’s native vegetation and led to
the extinction of several native species,
including the Laysan rail (Porzana palm-
eri) and Laysan millerbird (Acrocephalus
familiaris familiaris). Fortunately,
Laysan ducks survived this onslaught,
and subsequently the rabbits were extir-
pated from the island in the early 1900s.
Small, isolated island populations
have high extinction risks. On Laysan,
numbers of the duck fluctuate and have
seldom exceeded 600 individuals. The
Laysan duck is vulnerable to extreme
weather, diseases, introduction of mam-
malian predators, and global sea level

rise. In 1993 and 1994, there was a large
die-off of Laysan ducks attributed to
emaciation and infestation with a worm,
Echnuria uncinata. Recognizing that
the Laysan duck was highly vulnerable
to extinction, the U.S. Fish and Wildlife
Service (FWS) and U.S. Geological
Survey (USGS) developed a partnership
to translocate these ducks to Midway
Atoll National Wildlife Refuge. After
careful consideration, the agencies chose
Midway Atoll because they judged that is
has the most promising logistical feasibil-
ity and potential to support translocated
ducks. The translocation was a team
effort led by the USGS Pacific Islands
Ecosystem Science Center and involving
the collaboration of the USGS National
Wildlife Health Center-Honolulu Field
Station and the FWS. The team took
great care not to translocate the internal
parasite, Echinuria, via Laysan ducks
to Midway Atoll, where it has not been
documented.
To maximize the chances for success,
we chose the healthiest candidates for
translocation. Biologists with the project
trapped the ducks on Laysan, gave the
birds a complete physical exam, and
treated them for Echinuria worms prior
to transport. In October 2004, 20 juve-
nile and pre-breeding island ducks went
on a 2- day, 600-km (370-mile) Pacific
voyage by boat from Laysan to Midway
Atoll (USGS 2005). In October 2005, an
additional 22 ducks made the same trip.
All birds survived the translocation with
nutritional and veterinary support.
Understanding mortality factors and
occurrence of disease is important in
managing threatened and endangered
species. Post-release monitoring with the
aid of radio telemetry helped us deter-
mine the fate of the translocated birds
and monitor their health during October
2004-2007. Identifying the causes of
mortality and disease allows for explora-
tion of management options to address
the problems and enhance recovery of
the species. The refuge staff sent all
carcasses suitable for examination to the
USGS National Wildlife Health Center-
Honolulu Field Station for complete
examination to determine cause of death.
In other cases, suspected causes of death
were apparent from field signs.
To date, the identified causes of
Laysan duck mortality on Midway are
varied. Causes of duck mortality on
Midway have included egg-bound
females, trauma, yolk sac infection,
emaciation, and botulism. Field evidence
also suggests mortality from attacks by
large seabirds and vagrant birds of prey.
Fortunately, we have yet to document
the presence of Echnuria on Midway,
although biologists continue to monitor
for the disease. Avian pox lesions spread
by introduced mosquitoes on Midway
Atoll are common in the native Laysan
albatross (Phoebastria immutabilis) but
have not been observed in the ducks,
probably because the virus that causes
pox is specific to particular types of
birds. All mortalities observed in Laysan

Despite these mortality incidents,
the Laysan duck continues to flourish
on Midway Atoll, and the population
has increased after only three breed-
ing seasons. Juvenile recruitment has
exceeded adult mortality during the first
three breeding seasons, and number of
eggs laid per female on Midway is higher
than of those on Laysan. This reflects the
suitability of Midway’s habitat for Laysan
ducks. Furthermore, the translocation
has established a second population
of the species and more than doubled
its range from four to nine square km
(1.5 to 3.5 square miles). All of the 42
founding birds survived the transport
to Midway and 90 percent survived
their first year post-release, similar to
the survival rate on Laysan Island. The
ducks bred successfully after the first
year of release, and they produced the

first generation of fledglings in 2005. On
Laysan, one-year-old ducks typically do
not successfully breed, so the productive
first year at Midway Atoll was a pleas-
ant surprise. The total population size
of Laysan ducks on Midway has grown
from the original 42 translocated birds
to an approximate count of at least 192
post-fledgling juveniles and adults (see
Table). Interestingly, we placed the
ducks translocated to Midway Atoll onto
its two islands (Eastern and Sand), and
ducks now routinely fly between the
islands. On Laysan, the ducks rarely fly
over the ocean.
This story is an example of what can
happen when agencies and people work
together toward a common goal. In this
case, the clear winner is the Laysan duck,
whose risks of extinction are less today
than three years ago. Depending on
habitat suitability and absence of mam-
malian predators, future translocations
may take place on other islands, thus
making the future of this endangered
species a bit less uncertain with each
additional reintroduction. A visitor
services program to Midway Atoll NWR
is beginning this year (Barry Christenson,
FWS Midway Atoll Refuge Manager,
personal communication; www.fws.gov/
midway/VSP /MidwayVSPindex.html),
allowing visitors to see Laysan ducks
in the wild during their non-breeding
season (October to March). The Laysan
duck translocation team was honored
with the FWS Recovery Leader Award in
2007 for achieving a milestone toward
the species’ recovery (see http://www.
