Abstract and Figures

The total number of brown bears (Ursus arctos) in Europe is presently about 50,000 (about 14,000 outside Russia), within an area of more than 2.5 million km2 (800,000 km2 outside Russia). About 37,500 bears are found in the northeastern European population; 8,100 in the Carpathian Mountains; 2,800 in the Alps-Dinaric-Pindos; 1,000 in Scandinavia; 520 in the Rila-Rhodope Mountains; 200 in the Stara Planina Mountains; 50-65 in the western Cantabrian Mountains; 40-80 in Apennine Mountains; 20 in the eastern Cantabrian Mountains; 6 in the Western Pyrenees; 5 in the Central Pyrenees; and 4 in the southern Alps. The brown bear is either a protected or game species in all of the countries discussed in this paper. Most countries manage the brown bear at the national level, although several ministries are often involved. All European countries with bears within their national borders (except Bosnia and Herzegovina and the Yugoslav Federation) have signed the Bern Convention; almost half have prepared, or are preparing, a management plan for brown bears. In addition, most countries engage in monitoring, research, information dissemination, and conservation activities. In areas where bear range includes human settlements, damage to livestock, orchards, and beehives occurs but, in most countries, stakeholders are compensated for damage, either by the state, regional government, or hunter clubs. In 1995-96 about 1.15 million US$ was paid to compensate such damage throughout Europe.

Abstract: The total number of brown bears (Ursus arctos) in Europe is presently about 50,000 (about 14,000 outside Russia), within an area of more
than 2.5 million km2 (800,000 km2 outside Russia). About 37,500 bears are found in the northeastern European population; 8,100 in the Carpathian
Mountains; 2,800 in the AlpsDinaricPindos; 1,000 in Scandinavia; 520 in the RilaRhodope Mountains; 200 in the Stara Planina Mountains; 50
65 in the western Cantabrian Mountains; 4080 in Apennine Mountains; 20 in the eastern Cantabrian Mountains; 6 in the Western Pyrenees; 5 in the
Central Pyrenees; and 4 in the southern Alps. The brown bear is either a protected or game species in all of the countries discussed in this paper. Most
countries manage the brown bear at the national level, although several ministries are often involved. All European countries with bears within their
national borders (except Bosnia and Herzegovina and the Yugoslav Federation) have signed the Bern Convention; almost half have prepared, or are
preparing, a management plan for brown bears. In addition, most countries engage in monitoring, research, information dissemination, and conser-
vation activities. In areas where bear range includes human settlements, damage to livestock, orchards, and beehives occurs but, in most countries,
stakeholders are compensated for damage, either by the state, regional government, or hunter clubs. In 199596 about 1.15 million US$ was paid to
compensate such damage throughout Europe.

Brown bears originally occurred throughout Europe,
except on large islands such as Iceland, Gotland, Corsica,
and Sardinia; their former occurrence on Ireland is still
debated (Kurtén 1976, Corbets and Harris 1991). Later
the species disappeared from most areas as the human
population grew and suitable habitat was destroyed by
deforestation and agriculture. In addition, the extermina-
tion of bears was often encouraged as a means of elimi-
nating livestock depredation, with bounties paid by the
state, local authorities, or both, for killing bears. This was
effective because bears have a low reproductive rate and
are sensitive to high harvest rates. Eventually, the combi-
nation of human persecution and habitat destruction led
to the extermination of bears from most of western Eu-
rope and many areas in eastern and northern Europe
(Swenson et al. 1995, Rauer and Gutleb 1997,
Breitenmoser 1998).
In this paper we summarize population status, distribu-
tion, and management status of the European brown bear
populations covered in the Action plan for the conserva-
tion of the brown bear in Europe (Swenson et al. 2000).
This action plan is complementary to, and a refinement
of, the International Union for the Conservation of Na-
ture and Natural Resources (IUCN) Bears: Status survey
and conservation action plan (Servheen et al. 1999). The
separate European action plan was prepared for several
reasons.
1. Much of the data from Europe in the world-wide
plan was collected in the early 1990s and was out-
dated when published in 1999.
2. Political conditions in large parts of Europe have
changed rapidly over the last decade; the war in
the former Yugoslavia ended and new countries
were established with new legal conditions for bear
management and conservation; the European Union
(EU) expanded its territory and as more countries
joined (Austria and Sweden in 1995) and others
applied for membership, large carnivore manage-
ment and conservation changed.
3. Three re-introductions or augmentations of bear
populations (in Austria, France, and Italy) have
taken place in western Europe from 1989 to 2000.
The 2 action plans also adopted different approaches.
Servheen et al. (1999) analyzed the needs and threats of
each countrys bear population separately. Swenson et al.
(2000) used a population basis, stressing the need for a
continental approach and co-ordinated national efforts.
This pan-European approach was chosen because most
European brown bear populations are shared by
neighbouring countries. The European action plan was
endorsed by the IUCNBear Specialist Group, the Inter-
national Association for Bear Research and Management
(IBA), and the Council of Europe. It was also published
by the Council of Europe as an official document within
the legal framework of the Bern Convention.
METHODS
We used the following definitions:
Europe includes the countries west of the borders of
the former Soviet Union and Turkey, but also includes
the Baltic countries and Ukraine. This definition is con-
sistent with that of the Large Carnivore Initiative of Eu-
rope (Swenson et al. 2000). In an effort to present complete
population sizes, we include the bear populations in the
former Soviet Union that are contiguous with the popula-
tions we consider in this paper.
A population consists of the bears in an area that are
10 Ursus 12:2001
genetically isolated, totally or substantially, from other
bear populations. A population may consist of several sub-
populations. A sub-population consists of bears in an area
that have male-mediated genetic interchange with bears
in nearby areas, but little or no contact or interchange
among females.
All data were obtained by a standard questionnaire
mailed out to bear researchers and governmental agen-
cies dealing with bear management in each country with
bear occurrence. We tried to obtain more than one answer
per country. All respondents to our questionnaire are listed
in Table 1; all the information in this paper, if not indi-
cated otherwise, is based on their responses. We obtained
data from all European countries with bear populations
(Table 2).
We stress that population numbers are all estimates de-
rived by different methods and are not directly compa-
rable. Bears are notoriously difficult to census (Kendall
et al. 1992, Miller et al. 1997), and many estimates, espe-
cially those based on observations from the public, are
likely overestimates (Swenson et al. 1995). Estimates in
south-eastern Europe are often derived from counts made
by hunters at feeding sites that are carried out during 1 or
2 nights per year. These estimates are based on the un-
tested assumptions that 8090% of the bear population
visits feeding sites during this period and that no bear vis-
its more than one site (D. Huber, University of Zagreb,
Zagreb, Croatia, personal communication, 1998). Even
the estimates from Scandinavia, which are based on
marked to unmarked ratios of bears observed in 2 areas,
are based on an extrapolation to the rest of the brown bear
range (Swenson et al. 1994). Given these uncertainties,
estimates reported here must be regarded as approximate,
but the ranking of the populations by size is relatively
accurate.
RESULTS
Size and Distribution of Populations
Northeastern Europe (37,500 bears).The Northeast-
ern European population is estimated at about 37,500
bears, and is thereby the largest continuous brown bear
population in Europe. The population is found between
53°N in the south to 69°N in the north and stretches from
the Ural Mountains in the east to the west coast of Fin-

land (Fig. 1). As it is contiguous with bears on the east
side of the mountains in Russia, it is part of the largest
brown bear population in the world. Although the fence
along the FinlandRussia border is a potential barrier, the
Finnish-Norwegian population has received a net influx
of dispersing bears from Russia (Pullainen 1990). In Fin-
land, the species has re-established most of its former range
after the population bottleneck at the beginning of the 20th
century (Nyholm and Nyholm 1999). In Norway, 821
bears are restricted to Sør-Varanger Municipality (espe-
cially the Pasvik Valley), though there are occasional
sightings in the eastern part of the Finnmark Plateau
(Swenson and Wikan 1996).
Carpathian Mountains (8,100 bears). The Carpathian
population includes the brown bears in Slovakia, Poland,
Ukraine, and Romania (Fig. 1). The Carpathian Moun-
tains population is estimated to be about 8,100 bears and
is the second largest in Europe. The population increased
rapidly in the second part of this century (Frackowiak et
al. 1999, Hell and Findo 1999, Ionescu 1999), and re-
cently the Slovakian and Polish bear population was re-
connected with its Ukrainian counterpart. This range
expansion occurred rapidly; about 200 km in less than 20
years. Knowledge of the status of females in this expan-
sion area would be of great interest because, based on
data from the Scandinavian population (Swenson et al.
1998), one would expect to find few females in this newly
colonized area. Female brown bears in the Apusen Moun-
tains of western Romania are probably partly isolated from
the remaining Carpathian population, but interchange of
males is suspected to occur.
The Carpathian population probably consists of 3 sub-
populations. No further increase in range and population
size is expected because the population in the 4 countries
has reached or passed its optimal number, and nearly all
suitable habitat is occupied (Frackowiak et al. 1999, Hell

and Findo 1999, Ionescu 1999).
Alps–Dinaric–Pindos (2,800 bears).This population
consists of brown bears in the forested areas extending
from the eastern Alps in Austria and northeastern Italy in
the north to the Pindos Mountains in Greece in the south,
and spans parts of Austria, Italy, Slovenia, Croatia, Bosnia
and Herzegovina, former Yugoslav Republic of
Macedonia, the Yugoslav Federation, Albania, and Greece.
The total AlpsDinaricPindos population numbers about
2,800 bears. The forested areas in these countries are less
continuous than in the Carpathian area, separating the func-
tional habitat into more or less isolated sub-areas, although
there is some inter-connectivity. This suggests that the
population may be divided into several sub-populations
(Sørensen 1990) or may become distinct populations if
these corridors become unusable due to human activities.
The population estimates for the Yugoslav Federation,
Bosnia and Herzegovina, and especially Albania are quite
uncertain. Additionally, the effects of the war and politi-
cal instability on the bear population are unknown, but
may be severe, at least locally (Huber 1999). Three bears
were released into central Austria in 198993 in an area
with a naturally occurring male bear (Rauer and Gutleb
1997). Reproduction occurs regularly in this sub-popula-
tion, which now consists of about 1316 bears (Zedrosser
et al. 1999). We consider this a sub-population because

BROWN BEARS IN EUROPE Zedrosser et al. 13
there is movement of male bears, but not female bears,
between central Austria and the rest of the AlpsDinaric
Pindos population.
Scandinavia (1,000 bears).After heavy persecution
in Norway and Sweden, the once-numerous brown bear
population in Scandinavia was reduced to about 130 indi-
viduals by 1930 (Swenson et al. 1995). The population
has since increased to between 800 and 1,300, of which
more than 95% are in Sweden. Female brown bears are
mostly confined to 4 areas in Sweden that probably rep-
resent the areas where remnant populations survived in
about 1930 (Swenson et al. 1994). Male bears may dis-
perse between neighbouring female core areas, but when
considering demographic viability, each of the 4 should
be considered as separate sub-populations (Taberlet et al.
1995). In Sweden, the distribution of bears now resembles
that of 1800, with bears occurring in 50% or more of the
country. In Norway, bears are usually found along the
Swedish border, and most individuals are dispersing young
males from Sweden (Swenson et al. 1998). The popula-
tion is the most productive yet documented in the world,
and increased at a rate of 1015% annually between 1985
and 1995 (Sæther et al. 1998).
RilaRhodope Mountains (520 bears).This popula-
tion is located in southwestern Bulgaria and northeastern
Greece (Mertzanis 1999, Spassov and Spiridonov 1999).
It includes 3 sub-populations in the Bulgarian Rila Moun-
tains and Pirin Mountains, as well as the subpopulation in
the western Rhodope Mountains on both sides of the bor-
der. Although the total population is about 520 bears, only
1525 are found in Greece. The connection between the
bears in Greece and Bulgaria is probably maintained by
males from Bulgaria. No further increase in range or popu-
lation size is expected because poaching in Bulgaria has
increased since the political changes of 1989 (Mertzanis
1999, Spassov and Spiridonov 1999).
Stara Planina Mountains (200 bears).This popula-
tion of about 200 bears is located along a 120-km area
that extends from ZlatitsaTeteven in the east, to the
Tryavna Mountains in west-central Bulgaria (Spassov and
Spiridonov 1999). It became isolated from the popula-
tions to the south and west early in this century after an
effort to exterminate the species. However, genetic inter-
change between the Stara Planina population and the Rila
Rhodope population may be possible through male
dispersal. As in the RilaRhodope population, no further
increase in range and population size is expected as a re-
sult of increased poaching since 1989 (Spassov and
Spiridonov 1999).
Small Isolated Populations
Five very small, isolated populations are found in south-
ern and western Europe, representing the remnants of a
once widespread brown bear population. In at least 3 of
these (Pyrenees, Southern Alps, and Eastern Cantabrians)
the threat of extirpation is high. Unless prompt action is
taken during the next few years, these populations will
undoubtedly vanish. To underscore this point, a small, iso-
lated European brown bear population in the Vassfaret
area of southern Norway, died out as recently as the late
1980s (Bækken et al. 1994).
Western (5065 bears) and Eastern Cantabrian Moun-
tains (20 bears).Brown bears are now found in 2 areas
of the Spanish Cantabrian Mountains. These populations
apparently have been separated since the beginning of the
century, and now show genetic differences. Today, they
are separated by 3050 km of mountainous terrain, and
interchange between the populations is unlikely
(Cienfuegos and Quesada 1999), due to unsuitable habi-
tat and a high speed railway and motorway that bisects
the area. The most recent population estimate for western
Cantabria is 5065 bears, distributed over 2,600 km2
(Palomero et al. 1993). The eastern Cantabrian Mountains
population is estimated to contain about 20 bears. Both
Cantabrian bear populations face similar conservation
problems. The populations are in steady decline due to
human-caused mortality, primarily a result of illegal snares
intended for wild boars (Sus scrofa) and poison intended
for wolves (Canis lupus) (Cienfuegos and Quesada 1999).
High human-caused mortality, combined with small popu-
lation size, makes survival of these populations very un-
likely unless appropriate management actions are
implemented soon.
Apennine Mountains (4050 bears).This population
is located in Abruzzo National Park and the area surround-
ing Italys Apennine Mountains and was estimated at 70
80 bears in 1985 (Boscagli 1990). However, since then
the population is thought to have decreased, and 4050
bears may be a more realistic estimate. This population
may increase because poaching has been reduced in re-
cent years and because areas surrounding Abruzzo Na-
tional Park have been protected to secure suitable habitats.
However, these bears survive in an area that is densely
populated by humans and there are potential conflicts
between bear conservation and human activities.
Western Pyrenees (6 bears).The Western Pyrenees
brown bear population inhabits a 1,000 km2 area that
straddles the national border between France and Spain
(Fig. 1), although only half of this area is used regularly
(Camarra 1999). Reproduction was most recently docu-
mented in 1995 and 1998, and the present population is
estimated to be 6 individuals. (Camarra 1999). This rem-
nant population is doomed to extinction unless drastic
measures, such as population augmentation, are taken
soon.
Southern Alps (4 bears).This population is located
14 Ursus 12:2001
in the province of Trentino in the northeastern part of the
Brenta Mountains in Italy (Osti 1999). The potential bear
habitat covers 1,500 km2, of which only 240 km2 is used
regularly by bears. Reproduction has not been documented
since 1989. Recently, DNA analysis of hair and excre-
ment samples revealed that only about 3 individuals
and no more than 4are likely to survive in this area
(Genovesi et al. 1999). Augmentation of this population
has begun, with 2 bears from Slovenia released in 1999
and another 3 in 2000. There are plans to release an addi-
tional 4 bears in 2001 and 2002. (P. Genovesi, National
Institute for Wildlife, Bologna, Italy, personal communi-
cation, 2000).
Reintroduced Populations
In Europe, bears were reintroduced into 2 areas with no
bears, and 2 populations have been augmented. The first
reintroduction occurred in eastern Poland, where 10 bears
were introduced into the Bialowieza area between 1938
and 1944. This introduction was not successful. Tracks
were last observed in 1947, except for one set of tracks
observed in 1963 which may have been from a dispersing
bear from Belarus (Buchalcyzk 1980, Jakubiec and
Buchalczyk 1987). The most recent introduction was in
the central Pyrenees Mountains (3 individuals in 1996
97), and the population now numbers 5 bears; this newly-
founded population is located about 150 kilometers east
of the Western Pyrenees population. Two augmentations,
one in central Austria and one in northern Italy, are de-
scribed in the sections AlpsDinaricsPindos, and South-
ern Alps, respectively.
International Agreements
A list of all countries participating in international agree-
ments covered by this paper is presented in Table 3.
Bern Convention: Convention on the Conservation of
European Wildlife and Natural Habitats (19 Sept. 1979,
Bern, Switzerland). The goal of the Bern Convention
is to preserve wild animal species and their natural habi-
tats. Member countries (Table 3) must pay special atten-
tion to endangered and potentially endangered species and
include protective measurements in planning and devel-
opment. Animal and plant species are listed within differ-
ent appendices, each representing a different stage of
endangerment. The European brown bear is listed in Ap-
pendix II (strictly protected fauna species). Actions must
be taken to enhance the special protection of species listed
in Appendix II; capture, keeping or killing, willful distur-
bance, and the possession and trade of these species is
forbidden. The re-colonization of indigenous species must
be promoted if doing so will enhance the likelihood of
preservation. Member countries can make reservations to
the Bern Convention regarding means or methods of kill-
ing, capture, or other exploitation of listed species.
CITES: Convention on International Trade in Endan-
gered Species of Wild Fauna and Flora (3 Mar. 1973,
Washington).All European brown bear populations are
listed in Appendix II. This appendix also includes all spe-
cies not in actual danger of extinction, but potentially en-
dangered if trade of specimens of this species is not strictly
controlled. Trade control is accomplished through special
export permits.
Biological Diversity Convention: United Nations Con-
ference on Environment and Development (UNCED) (5
May 1992, Rio de Janeiro, Brazil).The main objective
of UNCED is the conservation and sustainable use of bio-
logical diversity. A presupposition is the preservation of
ecosystems, natural habitats, and wild populations of spe-
cies of wild fauna and flora. The brown bear per se is not
mentioned specifically in this convention.

only). The European Commission (EC) should promote
programs to protect the brown bear in Europe and should
continue existing programs. These programs should cover
the entire EU. Actions for socio-economic development
will be promoted in return for communities having pro-
tective measures for the brown bear. Systems for bear
damage prevention and damage compensation should be
developed. A network of connected reserves and specially
protected areas should be established (called the
NATURA 2000 Network).
European Parliament Resolution, 22 Apr 1994 (A2-
0154/94, ABL C 128/427, 09.05.1994) (applies to EU
members only). The EC should not support and finance
development that would have a negative effect on bear
populations. Actions with negative impact on bear popu-
lations should be corrected by the establishment of pro-
tected areas and corridors for genetic exchange. Measures
to prevent the killing and capture of bears and protect bear
habitat should be undertaken. Financial support for dam-
age compensation, and compensation for economic re-
strictions due to bear conservation, should be provided.

called Flora-Fauna-Habitat Directive is to secure species
diversity by protection of habitats and protection of wild
fauna and flora. Actions must be taken by the member
countries to preserve all species of wild fauna and flora
and their habitats. The European brown bear is a priority
species of the European Union. It is mentioned in Appen-
dix II (species needing specially protected areas) and
Appendix IV (strictly protected species; capture, killing
and willful disturbance not permitted). The possession,
transport, and trade of Appendix IV species is strictly pro-
hibited. Exemptions can be given only if this has no nega-
tive impact on the preservation of the species; to prevent
serious damage to culture and livestock; public health,
sanitary and safety reasons; and for scientific, restocking,
and re-colonization purposes.
National Management
Most (17 of 22) countries covered in this paper manage
brown bears at the national level (Table 4). Although
management is carried out by a national entity, in 4 coun-
tries more than one ministry or state agency is involved in
bear management. Management is on the regional level
in only 3 countries; in 2 cases management is shared by
national and local (Croatia), or national, regional, and lo-
cal (Italy) entities. Eight countries have prepared, or are
preparing, a management plan for brown bears. Some type
of monitoring program or activity is carried out in 17 coun-
tries.
Hunting Management and Poaching
In Europe, as defined in this paper, the brown bear is
totally protected in 12 countries and a game species in 6.
In 4 countries the brown bear is a protected species, but
hunting is allowed by special permission from the gov-
ernment (Table 4).
European brown bears, because of their high produc-
tivity (Sæther et al. 1998, Tufto et al. 1999), can sustain
harvest rates exceeding sustainable harvest levels in North
American populations. In Slovenia, legal harvest during
the 1980s exceeded 14% of the estimated population an-
nually (Krcb e 1988). Over 700 bears were killed legally
each year in the populations covered in this paper (Table
4). Some of these bears are killed legally in protected popu-
lations as a management tool. We do not have any evi-
dence that legal hunting is reducing the size of a bear
population in Europe, except in Romania where popula-
tion reduction is a management goal.
In addition to legal hunting, bears are poached as nui-
sance bears, for trophies, or for economic reasons. As eco-
nomic and social conditions have worsened in countries
such as Albania, Bulgaria, Bosnia and Herzegovina, Ro-
mania, the Yugoslav Federation, and Macedonia, poach-
ing probably occurs more often. Poaching of bears is also
a problem in the Nordic countries, where semi-domestic
reindeer are raised. However, illegal killing may also be
unintentional, for example when bears are killed by snares
set illegally for wild boars or by poisoned baits set ille-
gally for wolves. In fact, these are important sources of
bear mortality in Spain.
Management of Bear-caused Problems
The effective guarding techniques necessary for coex-
istence of livestock husbandry and large carnivores have
vanished in many areas of Europe (Kaczensky 1996);
partly due to economic, social, and political changes, and
partly as a result of the extermination of large carnivores
in most of their former ranges. For this reason, damage to
livestock occurs in many areas where the bear range in-
cludes human settlements. In addition, bears damage oats,
orchards, and beehives in some areas. There is compen-
sation for damage in most countries (64%), either by the
national or regional government (57%) or hunter clubs
(21%, Table 5). In Slovakia and Austria, damage is com-
pensated by either national or regional governments, or
by hunters. Usually compensation is not linked to the
owners effort to prevent damage. In 199596 about US$
1.15 million was paid to compensate for bear damage
throughout Europe.
The vast majority of livestock lost to bear depredation
in Europe are sheep (Table 5). In Finland, Norway, and
Sweden, semi-domestic reindeer depredation is also sig-

nificant. Damage to beehives is only important in a few
countries, with Greece experiencing the most cases of
damage (Table 5).
DISCUSSION
We have observed 2 trends regarding bear population
size and development in Europe. First, all large and vi-
able populations (>1,000) are situated in either northern
or eastern Europe, whereas bear populations in western
Europe are usually very small and may not be viable (Table
2). This difference is most likely attributable to the differ-
ent attitudes of people and the differing historical and eco-
nomic development of the countries. Boitani (1995)

BROWN BEARS IN EUROPE Zedrosser et al. 17
describes a similar pattern for the wolf in Europe. We be-
lieve that communism in eastern Europe was not nearly
as destructive to bear populations as the political systems
in western Europe. This is possibly due to the fact that in
communist countries, bears were often managed for the
hunting purposes of a few hunters, including foreign hunt-
ers with hard currency. Also, hunting and gun-ownership
among the general public were strictly limited, thus re-
ducing the potential for over-hunting and poaching.
Second, the only populations that we consider viable
are those shared by 2 or more countries (Table 2). Almost
all the bears in Europe live in large transboundary popu-
lations in eastern or northern Europe. Less than 1% of all
European bears live in western or southwestern Europe.
The few populations that exist within a single country are
small and declining, and we do not consider them viable.
Some are so small that immediate action must be taken.
Conservation actions need to be taken on the national level,
but could be facilitated by international funds and exper-
tise.
We consider population reintroduction and augmenta-
tion of small populations necessary for the conservation
of the brown bear in some areas of Europe. The Polish
reintroduction of 193844 was unsuccessful because the
released bears were born in captivity and approached
people after their release. Most of these animals were killed
very soon after their release because of their potential risk
to human safety. (Buchalcyzk 1980). In 199697, a sec-
ond reintroduction of bears was attempted in the central
Pyrenees in France. Some of these bears started to kill
sheep in a nearby area. Local residents were not prepared
for the arrival of bears and bear damage, and this led to
major controversies and political troubles in France which
are still unresolved (Direction Regionalé de
lEnvironnement Midi-Pyrenies 2000). The failed rein-
troduction in Poland and the political problems in France
indicate the importance of protecting existing bear popu-
lations (Zeiler et al. 1999). It may be easier to recover
large carnivore populations when the population has not
been absent for many decades (Boitani 1995). But if rein-
troduction is chosen, great care has to be taken in the prepa-
ration of the project and solutions for possible problems
must be available in advance.
In some cases, augmentation is the only way to ensure
the survival of a small population that might otherwise
become extirpated. This has proven successful in Aus-
tria, where a population of 1316 animals has been estab-
lished (Zedrosser et al. 1999). The most recent
augmentation of a bear population started in 1999 in the
Adamello-Brenta National Park in Italys southern Alps.
In both cases, the few naturally occurring individual bears
were doomed to extirpation. But despite the positive signs
of population increase due to reproduction in Austria,
neither augmentation can be considered successful yet,
and the populations will not be secure until they connect
with the female population front of the expanding Alps
DinaricPindos population (Zedrosser et al. 1999; P.
Genovesi, National Institute for Wildlife, Bologna, Italy,
personal communication, 2000). This again demonstrates
the importance of cross-border cooperation in Europe.
Several international treaties affect the conservation of
brown bears in Europe. CITES and the Biological Diver-
sity Convention are world-wide treaties, whereas the Bern
Convention applies to Europe, and the EU-directives only
to EU member countries. The power of these treaties var-
ies according to the situation. Enforcement of the treaties
depends largely on the contracting parties and, unfortu-
nately, they are poorly enforced in several countries. In
addition, resolutions of the European Parliament are only
recommendations. In this context, non-governmental or-
ganizations play crucial roles as the driving forces behind,
and watch-dogs for the realization of treaties and laws.
Within the EU, brown bears have generally been con-
sidered protected species. This legal protection originated
because bear populations in the original EU countries were
small and threatened. With the accession of Sweden and
Finland this situation has changed because both countries
have large bear populations and a tradition of hunting. In
1992, the EU granted both Sweden and Finland exemp-
tions from Council Directive 92/43/EEC (Flora-Fauna-
Habitat Directive). Bear hunting in these countries is now
officially viewed as a way to reduce serious damage to
culture and livestock, and to protect public health and
safety, although hunting is actually a way to control popu-
lation increase. The situation for some of the new appli-
cants to the EU is similar to that of Sweden and Finland:
large bear populations are traditionally hunted, and
changes to this practice might not be accepted and may
result in increased poaching of bears. Here again, exemp-
tions will most likely be granted. There might be a need
for the EU to reconsider their general position on bears
and hunting. Certainly, hunting in small and fragmented
populations is not feasible, but legalization of bear hunt-
ing may increase acceptance for bears and thereby facili-
tate the conservation of viable bear populations.
The Action Plan for the Conservation of the Brown Bear
in Europe (Swenson et al. 2000) has now been published
as an official document of the Bern Convention and the
Council of Europe, and thus must be considered by all
member countries (only 3 European countries have not
yet signed: Georgia, Russia, and San Marino). Although
we believe the larger populations in Europe are viable,
we are concerned that the smaller, isolated populations
are on the verge of extirpation. Because countries in Eu-
rope are small in area, a bear dispersing 200 km may cross
several national borders and enter several different juris-
18 Ursus 12:2001
dictions. Thus management actions applied in any given
country may affect not only bears in that country, but the
entire population shared by several neighbouring coun-
tries. The adoption of this action plan by the Bern Con-
vention represents a unique opportunity for the
conservation of the brown bear in Europe.

... During recent centuries, killing of bears was promoted, often by bounties paid by the state or local authorities. Due to their low reproduction rates, this effectively reduced bear populations in the remaining parts of its range (Zedrosser et al 2001). This was facilitated by the development of firearms and increasing deforestation of the once widespread European primeval forests. ...
... Such initiatives and hunting restrictions became more common after World War I (Swenson et al 1995) and helped bears to survive in some of the most remote parts of Europe. During World War II, there was also an attempt to reintroduce bears to eastern Poland, which however failed soon afterwards (Zedrosser et al 2001). Since bears were regarded as valuable hunting species, hunting associations in several countries supported bear conservation and hunting regulations. ...
... Brown bears exist in 10 metapopulations across human-modified landscapes in Europe (Swenson et al., 2000;Zedrosser et al., 2001;Penteriani et al., 2018). Bears have very large spatial requirements, i.e., male home ranges can be up to several thousand square kilometers (Dahle and Swenson, 2003;Ć irović et al., 2015), and are highly affected by habitat loss and fragmentation (Nellemann et al., 2007;Calvignac et al., 2009;de de de Gabriel Hernando et al., 2021). ...
... protected areas network in Serbia could consider including habitats important for brown bears, which has been proposed as a good conservation measure in several other regions (Jerina et al., 2003;Nazeri et al., 2012;Mukherjee et al., 2021). The ongoing expansion of the European Union's Natura 2000 network can be particulary important in this regard.Considering that the conservation of bears in Europe must occurr in a human-dominated landscape, their long-term survival depends on their ability to coexist with humans (Zedrosser et al., 2001;Chapron et al., 2014;Morales-González et al., 2020). Our result can be used as a starting point to identify priority areas where appropriate measures need to be put in place before conflicts arise. ...

Natural habitats become increasingly degraded and fragmented due to rapid human expansion. The decreasing availability of high-quality habitats combined with a lack of connectivity among suitable patches and the low permeability of human-transformed landscapes endangers the survival of many species. Understanding the environmental conditions favoring a species’ distribution and the identification of movement corridors between populations is crucial for sustainable conservation and management. Serbia is the only European country inhabited by three different brown bear metapopulations, highlighting its crucial geographical position for establishing functional connections among these metapopulations. We used species distribution modeling to predict suitable habitats for the three bear metapopulations in Serbia at two spatial scales (5 and 1 km2). We combined the predictions from each metapopulation to define suitable habitats for range expansion. Further, we created landscape resistance maps to identify possible connectivity areas to promote gene flow between these metapopulations. Our results highlight that 1) the underlying processes of bear habitat selection at the coarse scale differ between metapopulations, mainly due to the differences in habitat availability; 2) > 60% of areas predicted as suitable for bears in Serbia are currently still unoccupied; 3) the south-eastern part of Serbia represents a key area for the connectivity between bear metapopulations in the future. However, the presence of several movement barriers, such as highways, highlights the need to implement adequate mitigation measures to increase habitat permeability. Because bears are a useful umbrella species for conservation actions, improvement of habitat quality and permeability will also positively affect many other species in this region.
... During recent centuries, killing of bears was promoted, often by bounties paid by the state or local authorities. Due to their low reproduction rates, this effectively reduced bear populations in the remaining parts of its range (Zedrosser et al 2001). This was facilitated by the development of firearms and increasing deforestation of the once widespread European primeval forests. ...
... Such initiatives and hunting restrictions became more common after World War I (Swenson et al 1995) and helped bears to survive in some of the most remote parts of Europe. During World War II, there was also an attempt to reintroduce bears to eastern Poland, which however failed soon afterwards (Zedrosser et al 2001). Since bears were regarded as valuable hunting species, hunting associations in several countries supported bear conservation and hunting regulations. ...

Europe is densely populated and extensive wilderness areas are almost non-existent. Nevertheless, we share the continent with roughly 17,000 brown bears (Ursus arctos) in what is considered an example of the coexistence model. In contrast to the separation model, where bears and people are kept apart, the coexistence model promotes sharing of the same landscape. However, coexistence between people and bears is challenging and often results in a variety of conflicts: from damage caused to human property to direct threats to human safety that lead to the killing of bears. Several factors affect the probability of these human-bear conflicts and a good understanding of the drivers behind the development of ‘problem bear’ behaviour is essential when designing effective management measures. The toolbox of human-bear conflict management includes practices such as livestock guarding dogs, electric fences and aversive conditioning of problem bears. Largely unique to Europe is the use of artificial diversionary feeding of brown bears, whereby food is placed in remote areas in order to keep bears away from human settlements. Despite being practised for a long time in many countries, it is only recently that the broader spectrum of positive and negative consequences of this controversial measure has been understood. Public opinion is an important issue in the use of some conflict prevention measures; in some cases, local people react against lethal methods, especially where bears occur in small numbers. Recent advances in the science of human-bear conflicts offer a promise of continuing coexistence between people and brown bears, which are making a slow but steady return to many parts of Europe where they have been exterminated in the past. This also brings potential benefits that are associated with bear presence, such as ecotourism and ecosystem services provided by the bears. DECLINE AND RECOVERY OF THE LARGEST CARNIVORE IN EUROPE After the extinction of the cave bear (Ursus spelaeus s. lat.) and retreat of the polar bear (Ursus maritimus) to the north, brown bears remained the only bear species extant in Europe since the end of the last glaciation. In historic times, brown bears roamed throughout the European continent, including Britain, but with the increase in human population and growing pressure on the environment and wildlife populations, brown bear range also gradually decreased.
... To have a clear vision of the habitats of the brown bear within the study area, geospatial modelling was performed, considering all the factors that make up the habitat of this species using open-source data. Bears are an umbrella species; thus, understanding and improving ecological connectivity for bear populations should create benefits for other species inside the habitat [19]. This modelling was the starting point for studying habitat fragmentation, detecting ecological barriers, and generating ecological corridors within the distribution area of the brown bear, focusing mainly on hunting grounds (Figure 1). ...

The brown bear (Ursus arctos arctos) is the only bear species on the Romanian territory, its natural habitat occupying a third of the country’s surface, including the entire mountain area as well as the hills in the immediate vicinity. The bear population in Romania is the largest in Europe, increasing every year due to legislative protection, the species being present in Annex II of the Habitats Directive. The fragmentation of the bears’ habitat is the main cause of conflict occurrences between bears and the human population, which have occurred increasingly often in recent years. The main aim of this study is the ecological diagnosis of lands populated with bears in Romania to identify the highest quality habitats within the hunting grounds and to identify possible ecological corridors aimed at preserving the connectivity between them, using GIS spatial analysis techniques and taking into account the ecological conditions needed for the brown bear to survive. Following the spatial modelling of the open-source data, it was possible to observe the presence of habitats of the highest quality that could support a bear population outside the areas where bear specimens are concentrated (the counties of Mureș, Bistrița, Harghita, Covasna, Neamț, Buzau, Vrancea, Prahova, Brașov, Sibiu, and Argeș). The analysis of these habitats, where the bear population has exceeded the optimal level that they can support, highlighted that to allow the passage of bear specimens from one habitat to another, it is necessary to create ecological corridors in several key areas deducted on the basis of mathematical models.
... Most of the studies of the Brown bear (Ursus arctos) are focused on their habitat and geographic expansion [33,15], their conservation [31,32] and reproduction [12,31]. Morpho functional and histological studies of the Brown bear stomach and adrenal glands were conducted in the recent years [25,26]. ...
... The brown bear (Ursus arctos) is a large bear with the widest distribution of any living ursid (Serhveen et al. 1999). The brown bear's principal range includes parts of Russia, Central Asia, China, Canada, the United States, Scandinavia, the Carpathian region, Anatolia, and Caucasus (McLellan et al. 2008;Zedrosser et al. 2001) The normal range of physical dimensions for a brown bear is a headand-body length of 1.4 to 2.8 m and a shoulder height of 70 to 153 cm. The tail is relatively short, as in all bears, ranging from 6 to 22 cm in length (Parker 1990;Nowak 1999). ...

The aim of this study is to reveal the macroscopic features of the brown bear (Ursus arctos) os penis (baculum), as well as its morphometric measurements with the help of computerized tomography and digital electronic caliper. The study material was obtained from an adult male brown bear weighing approximately 400 kg, which was brought to the Wildlife Protection and Rehabilitation Unit of Kafkas University and died as a result of a traffic accident in the Sarıkamış district of Kars. After the skin and soft tissues around the baculum were removed, they were kept in hydrogen peroxide for 2-3 hours. In the macroscopic examination, it was determined that the baculum was straight, close to the pen, except for a slight curve in the distal part, and ended with a small tubercle at the distal end. A small notch was found in the proximal part. In addition to the prominent sulcus urethralis in the ventral of the baculum, a short groove was also detected in its lateral. A cartilage tissue of 11.08 mm in length and 4.67 mm in thickness was determined in the distal of the bone. In the morphometric measurements made with a digital electronic caliper, the length of the baculum was 148.95 mm, while the diameters were measured as 4.58 mm in the distal and 13.72 mm in the proximal, respectively. In computed tomography, baculum length was 148.84 mm, distal diameter length was 5.63 mm, and proximal diameter length was 13.12 mm. In addition, computed tomography measured the length of the cortex as 0.76 mm, the length of the medulla as 5.74 mm in the distal, the cortex length of 0.77 mm and the medulla length of 5.32 mm in the proximal region. As a result, in this study, the macro anatomical and morphometric features of the brown bear baculum, which live in high altitude and cold climate conditions, were revealed.

... Bears live in a great variety of habitats, including treeless arctic tundra, grasslands, boreal forest, forested and alpine mountains and deserts. Overharvest (hunting) and habitat destruction are the major reasons why brown bear populations have declined or have become fragmented in much of their range (Tsubota et al. 1987, Servheen 1990, Zedrosser et al. 2001, Dahle 2003. Originally, bears were found throughout Scandinavia (Collett 1911-12, Lönnberg 1929). ...

Abstract This is a report about the second year of collaboration between Biosphere Expeditions and Björn & Vildmark with the overall purpose of researching the behaviour of free ranging brown bears (Ursus arctos) in central Sweden for the Scandinavian Brown Bear Research Project (SBBRP). This collaboration investigates, amongst other topics, how climate change as well as human activities affect the brown bear behaviour and population, and provides managers in Sweden with solid, science-based knowledge to manage brown bears. From 28 May to 4 June 2022, six citizen scientists collected data on bear denning behaviour and feeding ecology by investigating the 2021/2022 hibernation season den sites of GPS-marked brown bears and by collecting fresh scats from day bed sites. All field work was performed in the northern boreal forest zone in Dalarna and Gävleborg counties, south-central Sweden, which is the southern study area of the SBBRP. After two days of field work training, citizen scientists were divided into three to four sub-teams each day. All study positions were provided by the expedition scientist and only data and samples from radio-marked bears with a VHF or GPS transmitter were collected. Citizen scientists defined den types (anthill den, soil den, rock den, basket den or uprooted tree den), recorded bed material thickness, size and content, as well as all tracks and signs around the den sites to elucidate whether a female had given birth to cubs during hibernation. All first scats after hibernation and hair samples from the bed were collected, and the habitat type around the den and the visibility of the den site were described. Twenty-six winter positions of 21 different bears were investigated. Two bears shifted their dens at least once during the hibernation season. In total, the expedition found 23 dens; two soil dens, eight anthill dens, one anthill/soil den, one stone/rock den, four dens under uprooted trees and seven basket dens. Unusually, one pregnant female that gave birth to three cubs during winter, and four females that hibernated together with dependent offspring spent the winter in basket dens. Normally basket dens are mainly used by large males. Excavated bear dens had an average outer length of 2.0 m, an outer width of 2.2 m, and an outer height of 0.8 m. The entrance on average comprised 28% of the open area. The inner length of the den was on average 1.3 m and the inner width was 1.1 m. The inner height of the dens was on average 0.6 m. Bears that hibernated in covered dens used mainly mosses (47%), field layer shrubs (36%) and branches (14%) as nest material, which reflected the composition of the field layer and ground layer that was present at the den site. However, bears that hibernated in open dens such as basket dens, preferred branches (43%) followed by grass (26%); mosses (19%) and field shrubs (12%) as nest material. The expedition found two first post-hibernation bear scats at the den sites. Ten bears selected their den sites in older forests, and eleven bears in younger forests, only two bears hibernated in very young forest. The habitat around the dens was dominated by spruce (Picea abies) 37%, scots pine (Pinus sylvestris) 35% and birch (Betula pendula, Betula pubescens) 27%. As part of its intensive data collection activities, the expedition investigated about half of all winter den positions that the SBBRP recorded in 2021/2022 and collected 64 scats at cluster positions, which represents all scat samples that the SBBRP normally collects during a time period of 14 days. A detailed food item analysis will be performed in 2025 and the data will be published. It appears that climate change is altering bear denning behaviour and may reduce food resources that bears need for fat production. Overharvesting (hunting) of bears and habitat destruction are the major reasons why brown bear populations have declined or have become fragmented in much of their range. In Scandinavia, human activity around den sites has been suggested as the main reason why bears abandon their dens. This can reduce the reproductive success of pregnant female brown bears and increases the chance of human/bear conflict. Understanding denning behaviour is critical for effective bear conservation. Further research is needed to determine whether good denning strategies help bears avoid being disturbed. Additionally, enclosed dens offer protection and insulation from inclement weather. A continued fragmentation of present bear ranges, inhibiting dispersal, together with an increasing bear population, might lead to bears denning closer to human activities than at present, thereby increasing human/bear conflict. The dens that were investigated by the expedition were visible from 22 m on average. Cover opportunities and terrain types not preferred by humans are thereby presumably important for bears that are denning relatively close to human activities, but further research needs to be done to validate this theory. Through all of the above, the expedition made a very significant contribution to the SBBRP’s field work in a showcase of how citizen science can supplement existing research projects run by professional scientists. Sammandrag Detta är en rapport om det andra året av samarbete mellan Biosphere Expeditions och Björn & Vildmark med det övergripande syftet att forska om beteendet hos vild levande brunbjörnar (Ursus arctos) i mellansverige för det skandinaviska björnforskningsprojektet (SBBRP). Samarbetet undersöker bland annat hur klimatförändringar och mänsklig aktivitet påverkar brunbjörnens beteende och population, och ger myndigheter i Sverige gedigen, vetenskapligt baserad kunskap för att förvalta brunbjörnstammen. Från den 28 maj till den 4 juni 2022 samlade sju expeditionsdeltagare in data om björnens idesval och födoval. De undersökte idesplatserna där björnar har legat i vintersömnen under säsongen 2021-2022 och de samlade samla färsk spillning från daglegor från GPS-märkta brunbjörnar. Allt fältarbete utfördes i norra boreala skogszonen i Dalarna och Gävleborgs län, södra mellersta Sverige, som är SBBRP:s södra studieområde. Efter två dagars utbildning inom fältarbete delades expeditionsdeltagaren in i tre till fyra grupper. Alla studiepositioner tillhandahölls av expeditionsforskaren och endast data och prover från radiomärkta björnar med en VHF- eller GPS-sändare samlades in. Expeditionsdeltagaren definierade idestyper (myrstackide, jordiden, steniden, korgiden eller iden under en rotvälta), och undersökte bäddmaterialet i idet, samt alla spår och tecken runt iden för att ta reda på om en hona hade född ungar under vintern. Alla första spillningar samlades in samt och hårprover från bäddmaterialed. Dessutom beskrevs habitatet och hur dold idet var placerad i terrängen. 26 vinterpositioner för 21 olika björnar undersöktes. Två björnar flyttade från sina iden minst en gång under vintersömnen. Totalt hittade expeditionsdeltagaren 23 iden; två jordiden, åtta myrstackiden, ett myrstackide / jordide, ett steniden, fyra iden under en rotvälta och sju korgiden. Ovanligt nog övervintrade en dräktig björnhona ett korgide där hon födde sina ungar under vintern. Dessutom övervintrade fyra honor med ungar i olika korgiden. Vanligtvis är det framförallt hanbjörnar som använder korgiden. Utgrävda björniden hade en genomsnittlig yttre längd på 2,0 och yttre bredd på 2,2 m och en yttre höjd av 0,8 m. Ingången utgjorde i genomsnitt 28% av det öppna yta. Den inre längden på idet var i genomsnitt 1,3 m och den inre bredden 1,1 m. Den inre höjden på idena var i genomsnitt 0,6 m. Björnar använde främst grenar (43%), gräs (26%) bärris (12%) och mossor (19%) som bäddmaterial, vilket återspeglade sammansättningen av fältskiktet och jordskiktet som fanns vid idesplatsen. Expeditionsdeltagare hittade två första björnspillningar efter vintersömnen. Tio björnar valde bygga sina iden i äldre skogar, elva i yngre skogar och två björnar övervintrade i väldigt ung skog. Habitatet runt idesplatsen dominerades av tall (Pinus sylvestris) 35%, gran (Picea abies) 37%, och björk (Betula pendula, Betula pubescens) 27%. Expeditionen undersökte ungefär hälften av alla vinterpositioner som SBBRP registrerade under 2021/2022 och samlade in 63 spillningar på klusterpositioner, vilket motsvarar alla av de spillnings-prover som björnprojektet normalt samlar in under en tidsperiod på 14 dagar. En detaljerad spillnings analys kommer att genomföras under 2025 och uppgifterna kommer att publiceras efteråt. Genom allt ovanstående gav expeditionen ett mycket viktigt bidrag till SBBRP: s fältarbete som visade hur expeditionsdeltagare kan komplettera befintliga forskningsprojekt som drivs av professionella forskare. Klimatförändringar förändrar björnens beteende och kan minska födotillgången. Intensiv björnjakt och förstörelse av habitat är de främsta orsakerna till att populationer av brunbjörnar har minskat eller blivit fragmenterade i stora delar av världen. I Skandinavien är mänsklig aktivitet kring idesplatser troligtvis det främsta skälet varför björnar byta iden. Detta kan minska reproduktionen bland dräktiga björnhonor och ökar risken för konflikt mellan människor och björnar. Förståelse av vinterbeteende är avgörande för effektiv bevarande av björnen. Ytterligare forskning behövs för att avgöra om goda vinterstrategier hjälper björnar att undvika störningar. Dessutom erbjuder väl isolerade ide skydd från dåligt väder. En fortsatt fragmentering av nuvarande björnstammen, som hämmar spridning, tillsammans med en ökande björnpopulation, kan leda till att björnar kommer närmare mänsklig bebyggelse, vilket ökar konflikterna mellan människa och björnar. De iden som undersöktes av expeditionen var synliga från 22 m i genomsnitt. Täta terrängtyper som inte föredras av människor är därmed förmodligen viktiga för björnar som bygger sina iden relativt nära mänsklig bebyggelse, men ytterligare forskning måste göras för att validera denna teori.
... Individual and seasonal variations in body size make identification of bear age by appearance almost impossible (Shirane et al. 2020;Shirane et al. 2021) except for cubs-of-theyear, and therefore tooth-based age estimation has been used to determine bear ages. In Europe and the United States, brown bears have been protected or carefully managed after dramatic population decreases (Zedrosser et al. 2001;Mattson & Merrill 2002). On the other hand, conflicts such as crop depredation, intrusion into human residential areas, and attacks on livestock and humans have become serious problems, and management agencies have developed policies to reduce these conflicts (Can et al. 2014;Bombieri et al. 2019). ...

Age is an essential trait for understanding the ecology and management of wildlife. A conventional method of estimating age in wild animals is counting annuli formed in the cementum of teeth. This method has been used in bears despite some disadvantages, such as high invasiveness and the requirement for experienced observers. In this study, we established a novel age estimation method based on DNA methylation levels using blood collected from 49 brown bears of known ages living in both captivity and the wild. We performed bisulfite pyrosequencing and obtained methylation levels at 39 cytosine-phosphate-guanine (CpG) sites adjacent to 12 genes. The methylation levels of CpGs adjacent to four genes showed a significant correlation with age. The best model was based on DNA methylation levels at just four CpG sites adjacent to a single gene, SLC12A5, and it had high accuracy with a mean absolute error of 1.3 years and median absolute error of 1.0 year after leave-one-out cross-validation. This model represents the first epigenetic method of age estimation in brown bears, which provides benefits over tooth-based methods, including high accuracy, less invasiveness, and a simple procedure. Our model has the potential for application to other bear species, which will greatly improve ecological research, conservation, and management.

Context Large carnivores have faced severe extinction pressures throughout Europe during the last centuries, where human-induced disturbances reached unprecedented levels. In the late twentieth century, the Cantabrian brown bear population was on the verge of extinction, due to poaching. Yet, the end of the last century was a turning point for this population. Presence data on the western Cantabrian subpopulation was collected since the beginning of the century and insights provided by this long-term monitoring may be useful for brown bear conservation. Objectives Here, we aim to: (i) identify the landscape features relevant to bears’ recovery; and (ii) understand if and how the landscape use patterns by bears changed over time. Methods We tested the influence of landscape structure (i.e., composition and configuration) on bear occurrence patterns using MAXENT in three periods representative of land cover change. Results Despite variation across the 19-year monitoring period, brown bears were more often detected near broad-leaf forests and bare rock areas and at lower to intermediate altitudes, but avoided arable lands, permanent crops, and burnt areas. Human population density or distance to roads—often used for modelling habitat suitability for Cantabrian brown bears—were not identified as relevant variables for this brown bear subpopulation. Artificial areas were identified as relevant landscape features, but not as disturbance. Conclusions These findings reinforce the importance of preserving bears’ native habitats and provide new insights, namely on the use of humanized landscapes.

Fifteen brown bear (Ursus arctos) and three black bear (U. americanus) density estimates were obtained in Alaska during 1985 through 1992 using 2-9 replicates of capture-mark-resight (CMR) techniques in 17 different areas. Radiotelemetry used to document movement of marked animals into and from search areas eliminated the need to correct density estimates for edge or periphery effects caused by absence of geographic closure. To estimate population size, the authors used a maximum-likelihood estimator modified to accommodate temporary movements of marked animals into and from the search areas. Procedures provided density estimates that were repeatable, were comparable among areas, included estimates of precision, and were more objective than methods historically used to estimate bear abundance. Estimates were obtained within a wide spectrum of habitats and provided a range of Alaskan densities from 10.1 to 551 brown bears (all ages)/1000 km 2 and from 89 to 289 black bears (all ages)/1000 km 2. Brown bear densities were 6-80 times greater in coastal areas where abundant runs of multiple species of salmon (Oncorhynchus spp.) were available to bears than in interior areas.

We analyzed 3 aspects of the human dimension of large carnivore conservation in Austria. We examined hunter ranking of wildlife species and suggest that while hunters still remain negative to brown bears (Ursus arctos) and lynx (Lynx lynx), there are differences between those who live in provinces with a longer tradition of living with bears and lynx and those who have had little exposure to these large carnivores. We measured the attitudes of an urban population (Vienna) about the re-introduction of wildlife including large carnivores. People from Vienna supported large carnivore re- introductions, but much less than a reintroduction of herbivores or birds of prey. We analyzed the content of bear and lynx articles in Austrian hunting magazines since 1948. Bears especially have been consistently prominent in this media. Most articles came from provinces with bear and lynx presence. The number of negative personal statements remained constant, but the number of neutral or balanced statements greatly increased. Our study is a preliminary test of attitudes in Austria toward large carnivores. For successful future management of large carnivores in Austria, we emphasize the importance of further human attitude studies. The history of large carnivores and their management in Austria is similar to the history of large carnivores throughout Europe and North America. Wolves (Canis lupus), bears, and lynx were seen as vicious, blood thirsty killers; they were perceived as directly competing with humans for the good game animals (e.g. red deer (Cervus elaphus) and roe deer (Capreolus capreolus)), they oc- casionally killed livestock, and for most people, these predators were not considered worthy of existence (Lopez 1978, Breitenmoser 1998). Historically, large carnivore

Records of bountied brown bears Ursus arctos in Norway and Sweden were analysed to estimate population size in the mid-1800's, and changes in population size and distribution in relation to the bear management policies of both countries. In the mid-1800's about 65% of the bears in Scandinavia were in Norway (perhaps 3,100 in Norway and 1,650 in Sweden). Both countries tried to eliminate the bear in the 1800's; Sweden was more effective. By the turn of the century, the numbers of bears were low in both countries. The lowest population level in the population remnants that have subsequently survived occurred around 1930 and was estimated at 130 bears. Sweden's policy was changed at the turn of the century to save the bear from extinction. This policy was successful, and the population is now large and expanding. Norway did not change its policy and bears were virtually eliminated by 1920-30. Since 1975, bear observations increased in Norway. This coincided temporally with an abrupt increase in the Swedish bear population, and bears reappeared sooner in areas closer to the remnant Swedish populations. Both conditions support our conclusion that the bear was virtually exterminated in Norway and suggest that bears observed now are primarily immigrants from Sweden, except for far northern Norway, which was recolonised from Russia and Finland. Today, we estimate that the Scandinavian bear population numbers about 700, with about 2% in Norway (on average about 14 in Norway, 650-700 in Sweden). This is a drastic reduction in the estimate of bears in Norway, compared with earlier studies. The trends in bear numbers responded to the policies in effect. The most effective measures used in Scandinavia to conserve bears were those that reduced or eliminated the economic incentive for people to kill them. Our analysis also suggests that population estimates based on reports from observations made by the general public can be greatly inflated.

The urgent need for an effective monitoring scheme for grizzly bear (Ursus arctos) populations led us to investigate the effort required to detect changes in populations of low-density dispersed animals, using sign (mainly scats and tracks) they leave on trails. We surveyed trails in Glacier National Park for bear tracks and scats during five consecutive years. Using these data, we modeled the occurrence of bear sign on trails, then estimated the power of various sampling schemes. Specifically, we explored the power of bear sign surveys to detect a 20% decline in sign occurrence. Realistic sampling schemes appear feasible if the density of sign is high enough, and we provide guidelines for designs with adequate replication to monitor long-term trends of dispersed populations using sign occurrences on trails.

Based on data from radio-collared individuals, we present an analysis of the viability of two small populations of the Scandinavian brown bear, Ursus arctos. The northern and southern populations had different demographic characteristics, even though the population growth rate r and the demographic variance s(d)/2 were high in both populations (r = 0.13 and s(d)/2 = 0.180 in the north, and r = 0.15 and s(d)/2 = 0.155 in the south). In the northern population the environmental variance s(e)/2 was not significantly different from 0, whereas in the south s(e)/2 = 0.003. In the south, this was related to high environmental stochasticity in the survival rate of the youngest animals, which resulted in an increase in survival with age in this population. In contrast, in the north, the probability of survival showed a slight decrease with age. Uncertainties were obtained from the joint distribution of bootstrap replications of r, s(d)/2 and s(e)/2. Although the uncertainty in these estimates is quite large, it is unlikely that even relatively small populations (> 10 females ≥ 1 year old) will decline to size less than 1 after 100 years. Analysis of the distribution of the critical population size (i.e. the population size where the population's logarithmic growth rate is zero) shows that these brown bear populations must be larger than 3-4 females 1 year or older to secure a positive growth rate. Similarly, if we define a viable population as the population size where the chance of survival is greater than 90% during a period of 100 years, 8 females ≥ 1 year old must be present in the north and 6 females in the south. This high viability of even small brown bear populations is due to high reproductive and survival rates. A relatively small increase in the mortality rate will strongly reduce the viability of even relatively large brown bear populations.
