INTRODUCTION
The management and conservation of large carnivores is
one of the most challenging wildlife conservation issues
of our time. The global decline of large carnivores is tied
to the direct hunting of carnivores and their prey, along
with the loss and degradation of their habitat (Nowell &
Jackson, 1996; Hilty et al., 2006; Foster et al., 2010;
Estes et al., 2011; Ripple et al., 2014; Rabinowitz, 2015).
Whether the loss of large carnivores is direct or indirect,
and whether their loss is intentional or unintentional, the
effect on the communities in which they were resident
can have both immediate and long-term impacts (Estes
et al., 2011).
Protected areas play an important role in the
conservation of large carnivore populations by
supporting a wild prey base and often providing refuge
from direct persecution by people. However, large
carnivores range widely, often beyond the boundaries of
protected areas, where they may threaten livestock and
thus face increased risk of lethal control (Mills, 1991;
Woodroffe & Ginsberg, 1998; Payan et al., 2013). The
backlash from human residents near the protected areas
in such situations can be harmful to the conservation of
the carnivore population in the protected area, and it can
threaten the acceptance and purpose of the protected
area by local communities, who are mostly engaged in

ABSTRACT
Due largely to their success in undisturbed areas, the conservation of large carnivores is tied to protected
areas. However, because of their large area requirements, large carnivores and their conservation will
also always be linked to areas outside of protected areas. Retaliatory killing of jaguars near reserves and in
corridors between reserves threatens to severely decrease jaguar populations in protected areas and their
corridors, thus decreasing the ecological viability of protected areas for the species. Resolving this conflict
will allow jaguars to utilize the human-dominated landscape, provide opportunities for corridor
conservation, and enhance the effectiveness of protected areas. We review methods to reduce depredation
of livestock and prevent lethal control of jaguars. Approaches to mitigate conflict include insurance
schemes, management of wild prey, and above all, improving livestock husbandry and management.
Improvements that are recommended for specific problem farms and ranches might include electric
fencing, night enclosures, designs for newborn holding pens, the use of guard animals, and partial herd
immersion of creole cattle races or water buffalo. We describe multiple testing scenarios and results from
throughout Latin America for reducing livestock depredation across protected areas and agricultural
landscapes.

economic production unrelated to conservation (Treves,
2008). The resolution of this human-wildlife conflict
issue is dependent on the development of strategies to
decrease the conflict that carnivores create in the
landscapes surrounding protected areas. In Latin
America, there is a pressing need for solutions to
conflicts created by jaguars (Panthera onca) in the
landscapes surrounding protected areas.
Jaguars are the largest felid in Latin America. They
currently exist over more than 40 per cent of their
historic range (Rabinowitz & Zeller, 2010), much of
which is encompassed within protected areas, or near
them. In fact, our analysis, using the new IUCN range
map for jaguars1 and World Database on Protected Areas
(UNEP-WCMC, 2014) indicates that just over 50 per cent
of jaguar range is in protected areas or within 10 km of a
protected area (Petracca et al., unpublished data). Thus,
for both jaguars and humans, the mutually beneficial
results of reducing jaguarhuman conflict in and around
protected areas can affect a large portion of Latin
America. The most prevalent and direct source of conflict
is between jaguars and livestock producers; most jaguars
are killed in retaliation for livestock depredation, or the
perceived threat of it (Rabinowitz, 1984; Marchini &
Macdonald, 2012; Zarco-Gonzalez et al., 2013). The
losses of these jaguars particularly those that are
resident in both the protected area and the surrounding
multi-use lands threaten the integrity of the natural
communities of flora and fauna the protected areas are
designed to protect. Other primary reasons for jaguar
loss are habitat loss and opportunistic hunting (Nowell &
Jackson, 1996).
In this paper, we address the questions surrounding
jaguar survival in and around protected areas,
particularly those landscapes in which livestock
production is an important human activity. Using
preliminary data from farms currently being monitored,
plus a literature review, we attempt to offer solutions to
jaguar depredation questions, especially as they relate to
areas near protected areas. We also address two
questions: what actions can be taken to reduce jaguar-
livestock conflict, and how can these actions be
facilitated by protected area managers?
METHODS
This paper is a summary of depredation solutions
observed by the authors on more than 120 ranch sites,
ongoing research on 30 ranches (in Belize, Costa Rica,
Colombia and Brazil), and supporting data from
additional publications (Rosas-Rosas et al., 2008; Salom

-Perez, unpublished; Foster, 2008; Hoogesteijn &
Hoogesteijn, 20142). Geographic variation was not
considered to be an important influence in the
assessment of solution effectiveness in the depredation
solution observations; however, for the current
assessment of the ongoing research on 30 pilot ranches,
data on rainfall, vegetation composition, and additional
physical and biological characteristics are recorded.
Data were compiled through two approaches. First,
observations were made on ranches with and without
jaguar depredation issues; some ranches were visited due
to depredation activity; other ranches were visited
because they were in important jaguar areas. Second,
ranches with depredation histories were selected for
application of livestock management modifications.
Depredation activity after these modifications was
monitored. In nearly all cases specific information on
ranch operations were collected (e.g. number of
livestock, water sources, forested area, fencing design,
etc.) and this information was related to depredation
incidents and observations of the area. Prior to 2008, a
large amount of the data collected was collected
opportunistically. For instance, a depredation increase or
decrease was associated with some aspect of livestock
husbandry; additional applications of that method
produced similar results, and the method was termed
successful. Since 2008, 30 ranches have been assessed
and monitoring of depredation has taken place in a
regular and systematic fashion. At the 30 ranches
experimental applications include: electrical fencing on
12 ranches, night enclosures on 22 ranches, eight
separate new-born enclosures, two ranches with creole
cattle and two with water buffalo. Camera traps are
deployed to detect the presence of jaguars and other
predators.
RESULTS
To compile observations of depredation solutions, the
findings of more than 120 ranch visits over a period of
nearly twenty years were combined with monitoring data
from the 30 ranches. From this compilation more than a
dozen ranch modifications were tested and found
effective in reducing jaguar depredation or were highly
correlated with reduced jaguar depredation (see
discussion). Preliminary results are supported of
previous works of the authors (e.g. Hoogesteijn &
Hoogesteijn, 2014) and others (Rosas-Rosas et al.,
2008). Although data are still being collected, the 15
farms in Costa Rica, with electric fencing and night pens,
experienced no depredation during the first two years of
monitoring; six farms in Belize experienced no
depredation over 15 months of monitoring, with guard
animals and improved fencing; night pens in 14 Brazil
farms took depredation from six events to one over a
period of 18 months; and four farms using water buffalo
or creole breeds (Costa Rica, Colombia, and Brazil)
experienced no predation from herds monitored from six
months to four years. All of the above farms had
experience some level of jaguar attacks prior to the
application of depredation remedies.
DISCUSSION
Results from currently monitored farms display high
potential for reducing jaguar depredation. Although the
list of activities that help reduce depredation is an
extensive one, and the list is expected to become more
extensive and more detailed, below a reduced set of
activities that have been found to be particularly
successful is presented. These individual activities still
require further testing in a variety of conditions. What
works in one environment, might not work in another
(for instance, in our research, guard donkeys were
inexpensive and very effective in preventing jaguar
depredation in Belize, but in Costa Rica they were
prohibitively expensive even for testing). However, the
following were tested and found effective not only in the
current research, but in previous work (e.g. Salom-Perez,
unpublished; Foster, 2008; Hoogesteijn & Hoogesteijn,
2014).
Electric fences
One of the most important and effective tools available to
prevent predation by wild felids on cattle, sheep, pigs,
goats and fowl, is the use of electric fencing specifically
designed to repel predator attacks; we are currently
monitoring seven farms that have had no depredation
over two years; all of these farms had experienced
depredation losses prior to the implementation of electric
fencing. The specific designs of electric fencing
applications appear to effect results. Scognamillo et al.
(2002) used three strands at 30, 60 and 90 cm high
charged with 3,000 volts as being less effective than
when the system was charged with 4,500 to 5,000 volts;
eight attacks occurred in the former design and no
attacks occurred in the latter design.
Until now, the use of electric fencing has not been widely
used as a predator deterrent in Latin America. More
often, it has been used to keep domestic animals in
rather than keeping wild animals out. It is very important
to note that electric fences for livestock control, with one
or two strands of electrified wire, prevents cattle from
moving from one pasture to another, but is not effective
in preventing predator attacks. Fences must be
specifically designed to prevent the entry of jaguars. They
PARKS VOL 21.1 MARCH 2015

are therefore particularly useful when used in smaller
areas, such as corrals used as night enclosures, or smaller
pastures such as those used for late-stage pregnant cows
or newborn calves and their dams. Electric fences have
also been used to surround all the pastures of a farm,
especially when small, or around areas known to be at
high predation risk.
In the Venezuelan Llanos, Scognamillo et al. (2002)
initially tested a design with three strands of electric
wire. An 18 ha calving paddock with a 1,697 m perimeter
was surrounded with strands arranged at 30, 60 and 90
cm from the ground. Strands were charged with 2,500 to
3,000 volts. Felines were however not deterred by this
design. Subsequently, an additional negative strand was

& Corrales, Panthera

added at 85 cm from the ground, and voltage was
increased to 4,500-5,000 volts. With these modifications
the attacks ceased.
Another trial was conducted in the Brazilian Pantanal
(Cavalcanti et al., 2011). The fence consisted of two
electrified wires at 25 and 50 cm in height with a
5,000 to 7,000 volts charge. The perimeter was
approximately 14 km, enclosing several pastures. The
fence was regularly checked to prevent leakages of
energy or faulty wiring. Additionally, the fence and
sleeping areas of the herds were monitored during the
night by a ranch employee equipped with a powerful
spotlight and explosive deterrents. This system was
shown to be effective and decreased predation losses
over several years. However, the results suggested that
enclosing smaller pastures might have been even more
effective.
Night enclosures
A very effective action in areas with intense predation is
to enclose domestic animals in corrals, pens or small
pastures near human habitation during night time. If the
night enclosure has lights or is located near human
habitation with dogs, it is even more effective. These
night enclosures can also be provided with electric
fencing. The animals (whether cattle, pigs, sheep or
goats) are easily habituated to enter the corrals. The
action reduces predation impacts significantly but
necessitates a slight increase in farm labour and
operating costs. This action can also enhance animal
nutrition because concentrated feed and supplements
can be supplied within the enclosure.
These night enclosures have been tried in different sized
farms and various ecological settings. For example, in
Costa Rica, in the Nairi Awari Indigenous Reservation on
the Talamanca Mountains, jaguars and pumas (Puma
concolor) attacked and consumed domestic pigs that
freely foraged in the forests. When enclosed at night,
there was initially a significant decrease in attacks (from
several in previous years plus a jaguar killed in
retaliation), to zero attacks in the final year of the project
(Salom-Pérez, unpublished data). Along with the pens
bio-digesters were built to produce biogas from the
faeces of the animals locked-in at night. The use of
biogas eliminated the need to collect firewood, thus
minimizing ‘wood collection time’ in exchange for ‘pig
collection time’ and can reduce forest destruction in and
around protected areas. Additionally this practice had
the positive side effect of reducing harmful smoke
exposure from the wood stoves (Salom-Pérez,
unpublished data).
Control of breeding and protection of young
One critical element that can be integrated with all of the
solutions presented here is the control of breeding within
livestock herds. The control of breeding is an essential
starting point in the reduction of jaguar depredation.
Despite the fact that jaguars can kill prey much larger
than themselves (including adult cattle) smaller, younger
individuals are particularly vulnerable. Controlling the
time in which these individuals are present in the
landscape helps managers improve their safety.
Conversely, if breeding takes place year round, farmers
are constantly attempting to secure and care for newly-
born young. With the young, vulnerable individuals
presenting themselves during one particular period of
the year farmers can provide more easily for their safety
in a more efficient and focused manner.
The most effective management strategy is to keep
calves, calves and mothers and late-pregnancy livestock
in special holding pens. Holding pens should not be
pastures containing forested areas or be adjacent to
forested areas (Cavalcanti et al., 2011). Cows should be
placed in open pasture areas, and preferably close to
human dwellings. This countermeasure is easily applied
in small and medium-sized ranches, especially those that
are well organized and have a 3-4 months breeding
season, which limits the calving season to 4-5 months in
the year. Added protection can be afforded through the
use of electric fencing.
In Costa Rica, a combination of night enclosures and
electric fences for birthing areas eliminated predation on
young calves. This work was performed in twelve small
experimental farms located at the Barbilla-Destierro
Biological Sub-corridor and the San JuanLa Selva
Biological Corridor (D. Corrales and Panthera Costa Rica
Team, unpublished data).
Guard animals
Guard animals can take several forms. They can be older
animals within a herd, or they can be other species that
are placed in the herd to prevent attack. Preliminary data
from field experiments indicates that experienced older
animals (bulls, steers or older cows with horns) will often
confront predators, as evidenced by marks from injuries
on these animals, sustained by felids. Therefore, a certain
percentage of these animals should be retained in the
herd. These animals teach defensive grouping behaviour
to the younger animals thus reducing predation. Tortato
et al., (in press) documented this on a ranch in the
Brazilian Pantanal. The ranch had high frequency jaguar
and puma predation. A larger proportion of older
animals in the herds diminished losses. Between January
2006 and September 2010, 73 per cent of the deaths
PARKS VOL 21.1 MARCH 2015
68
Quigley et al
caused by jaguars and pumas happened when the
proportion of adults in the herd was lower than 60 per
cent. The authors (Tortato et al., in press) point out that
this is a less aggressive alternative to predator removal or
relocation that produces economic benefits in herd
production.
Additional protection can be provided with guard
animals. Guard donkeys (Equus asinus), grazing with
herds of cattle, have been effective in reducing jaguar
predation in Belize (S. Juan, pers. comm.) due to their
aggressive braying and their tendency to confront
threats. This experience is being tested experimentally,
with promising preliminary results in Belize (R. Foster &
Panthera Belize Team, unpublished data).
Creole cattle
The majority of cattle in tropical America are zebu (Bos
indicus) pure- or cross-bred with varying admixtures of
European breeds (B. taurus) introduced into the
Americas by Europeans in the 17th Century. Although
high proportions of adults, especially males, in a herd of
zebu can reduce predation (see above; due to size,
awareness and defensiveness), the original European
breeds (e.g. Nelore breed) retained a stronger, innate
defensive response to threats. For example, cows have
highly defensive reactions against predators and protect
their newborn from attacks while zebu breeds stampede
in the presence of a predator, leaving small calves alone,
disoriented and prone to attack.
Several hardy breeds of B. taurus are however notable
for their adaptation to New World wildlife, plants,
parasites, etc. and in particular to the harsh conditions of
the flooded savannahs of the Neotropics. Two of these
are the Creole/Criollo Llanero and the Pantaneiro
breeds, in the Colombian and Venezuelan Llanos and the
Brazilian Pantanal, respectively. Most of these breeds
have an inherent ability to defend themselves from
predator attacks (Calzadilla Valdés, 2007), and
demonstrate a gregarious herd behaviour similar to the
one exhibited by the Asian water buffalo (described
below). Most of these breeds however do not have the
good carcass conformation for meat production
demanded by modern markets. Consequently, they
almost disappeared.
Experimental use of these breeds is currently underway
to scientifically document their predation-deterring
capabilities, along with their rescue and recovery for
potential use in areas of high jaguar predation.
Preliminary results indicate the Creole breed effectively
reduced jaguar predation in herds totally made up of
Creole cattle (San Martiniero breed, Colombia; no
predation over a two-year period), in herds with only a
percentage of Creole cattle (San Mariniero breed mixed
herds, Colombia, no predation over two-year period;
Pantaneiro breed mixed herds, Brazil, no predation over
one-year period), and potentially in herds of first
generation crosses (F1 offspring) of Creole cattle with
PARKS VOL 21.1 MARCH 2015

zebu cattle, thus enhancing carcass and meat quality and
conserving the defensive traits. This latter experiment is
still underway, attempting to produce increased meat
production while observing if anti-predation behaviours
are retained. First-generation offspring are displaying
defensive behaviours when approached; depredation on
these individuals, in paired comparisons with zebu
breeds, will measure differences in field conditions.
Water buffalo
The Asian water buffalo (Bubalus bubalis) originates
from Southeast Asia and was domesticated nearly 5,000
years ago. Having evolved in the presence of a large
predator, the tiger (P. tigris), they exhibit gregarious
behaviour. When under a perceived threat, females form
a circle around their calves, while the bulls walk around
this circle, actively looking for predators. Buffaloes tend
to graze in closed groups never straying far away from
each other and aiding any member of the herd that calls
in distress.
A study conducted in four Venezuelan ranches which
held cattle and buffaloes together (Hoogesteijn &
Hoogesteijn, 2008) compared predation mortality
between the two species held in equal conditions. The
results found that the likelihood of cattle being preyed
upon by jaguars or pumas was 25 times higher than for
buffaloes. Buffalo had the same protective reaction
toward predator attacks, regardless of circumstances or
management systems in which the herds were kept.
The use of water buffalo is expanding in the Llanos of
Colombia and Venezuela. It is a more efficient and
profitable species than cattle in flooded savannahs, or
very moist environments, containing poor quality forage.
Buffalo are highly desired for their gentleness when
properly managed, plus their productivity, disease
resistance, and defensive behaviour are all qualities
which make them desirable over cattle. Their growth
curve, fertility and longevity are also better than those of
cattle under similar conditions. Although some
management requirements of the species must be strictly
adhered to (e.g. managing at or below pasture carrying
capacity, providing regular contact so as to maintain
docile temperament, etc.), dramatic reductions in jaguar
predation can be obtained with both full and mixed herds
of water buffalo. In Costa Rica, a group of six water
buffalo were introduced to a ranch that had recently
suffered attacks on livestock. In six months, no attacks
have occurred in the mixed group of cattle and buffalo,
while there have been two attacks in neighbouring
ranches (D. Corrales, unpublished data).
Hunting management
Human hunting of both jaguars and their prey can
influence jaguar depredation. First, the indiscriminate
and opportunistic hunting of jaguars can produce
crippled individuals that are not able to hunt their
natural prey, and thus they turn to the killing of livestock
(Rabinowitz, 1986). Second, and more importantly,
studies in several different environments have found a
positive correlation between the overhunting of game
species by humans and elevated levels of jaguar
depredation (see Polisar et al., 2003). In areas where
hunting is legal, strict enforcement of sustainable harvest
is essential. Especially in areas of South America in
which subsistence harvesting of wildlife is present, it
might be necessary to prohibit hunting if the
enforcement of harvesting quotas is not effective. Most
importantly for jaguars, these restrictions should also be
in place for such species as spectacled caiman (Caiman
crocodilus), capybaras (Hydrochoerus hydrochaeris),
peccaries (Tayassu tajacu and T. peccary) and pacas
(Agouti paca).
CONCLUSIONS
The seven actions suggested above are those we (the
authors) felt are most easily applied and most effective in
reducing jaguar depredation, supported by the literature
and on-going data collection. However, given the loss of
jaguars due to retaliatory killing, and the effects of that
killing on the integrity of protected areas, additional
resources must be brought to bear to enhance known
solutions, and new solutions. One critical element that
integrates with all of the above is the control of breeding
within the livestock herds, and is thus an essential
starting point in the reduction of jaguar depredation.
Despite the fact that jaguars can kill prey much larger
than themselves, including adult cattle, smaller, young
individuals are particularly vulnerable. Lastly, the
application of the above findings will require outreach
and education in the communities surrounding protected
areas if human wildlife conflict related to jaguars is to be
reduced and the acceptance of protected areas by
communities enhanced (see Wells & Brandon, 1992). In
all jaguar range countries, governments have the legal
oversight of wildlife and natural resources, including
jaguars. Likewise, the establishment and oversight of
protected areas is also directed by government.
Commonly, these two government responsibilities are
under one government agency or institution. In addition,
in most jaguar range countries, agricultural ministries
oversee the health and production of livestock, especially
herds that are supplying livestock products (e.g. meat,
milk, etc.) to the general public. Involving all these
government entities, and integrating their policies in anti
PARKS VOL 21.1 MARCH 2015

-predation activities is an important if not essential
part of the long-term reduction of jaguar depredation in
and near protected areas. Governments are becoming
more aware of the pervasiveness of the jaguar-livestock
conflict issue. At the same time, they are also becoming
aware that the problem is not solved by the constant
killing of depredating individuals. In addition, the
growing ecotourism industry in Latin America (Wallace,
1993; Stonza & Durham, 2008) provides added economic
incentives for maintaining complete assemblages of
native vertebrates, including large predators. Foster
(2008) analyzed the survival potential of jaguars in a
Belizean landscape and found that the current two
protected areas had the potential of supporting isolated
jaguar populations, but the probability of all populations
persisting for 100 years was approximately 50 per cent
unless dispersers from the core protected areas exceeded
12 percent per year. Thus, these landscapes and the
jaguar populations they support are dependent on the
interactions between protected areas and the more
human dominated landscape around them.

RESUMEN
Debido en gran parte a su éxito en áreas no perturbadas, la conservación de los grandes carnívoros está
ligada a las áreas protegidas. Sin embargo, debido a su necesidad de superficies extensas, los grandes
carnívoros y su conservación siempre estarán vinculados a zonas fuera de las áreas protegidas. La
matanza en represalia de jaguares cerca de las reservas y en los corredores entre reservas amenaza con
disminuir severamente las poblaciones de jaguares en las áreas protegidas y en sus corredores, con la
consiguiente reducción de la viabilidad ecológica de las áreas protegidas para la especie. La resolución de
este conflicto permitirá a los jaguares utilizar el paisaje dominado por humanos, deparará oportunidades
para la conservación de los corredores, y mejorará la eficacia de las áreas protegidas. Examinamos los
métodos para reducir la depredación de ganado y evitar el control letal de jaguares. Entre los enfoques para
mitigar los conflictos cabe señalar los planes de seguros, la gestión de presas silvestres, y sobre todo la
mejora de la cría y la gestión ganadera. Las mejoras que se recomiendan para problemas específicos en
granjas agrícolas y ganaderas pueden incluir cercas eléctricas, recintos nocturnos, diseños de corrales para
recién nacidos, el uso de animales de guardia, y la sumersión parcial de razas criollas de ganado o búfalos de
agua. Describimos múltiples escenarios de prueba y los resultados de toda América Latina para reducir la
depredación de ganado en áreas protegidas y paisajes agrícolas.
RÉSUMÉ
Due en grande partie aux succès remportés dans les zones non perturbées, la conservation de grands
carnivores est associée aux aires protégées. Toutefois, en raison de leurs exigences de matière d’espace, la
conservation de grands carnivores sera toujours liée aux régions à l'extérieur des aires protégées. L’abattage
de jaguars, en tant que mesure de représailles, se passe à proximité des réserves et dans les couloirs entre
les réserves et constitue une grave menace pour les populations de jaguar dans les aires protégées et leurs
couloirs, diminuant ainsi la viabilité écologique des aires protégées pour l’espèce. Seule une résolution de ce
conflit permettra aux jaguars de se déplacer à travers les territoires dominés par l'homme, ouvrira la
possibilité de mesures de conservation dans les couloirs et renforcera l'efficacité des aires protégées. Nous
examinons les méthodes permettant de réduire la déprédation du bétail et empêcher le contrôle létal de
jaguars. Les conflits humains-faune peuvent être gérés grâce à des approches variées tels des systèmes
d'assurance, la gestion des proies sauvages et surtout l’amélioration des techniques d'élevage. Certaines
améliorations recommandées pour les fermes et les ranches sont, par exemple, des clôtures électriques, des
enclos de nuit, des enclos d'hébergement pour nouveau-nés, la présence d'animaux de garde, et
l’incorporation partielle du bétail créole ou des buffles d'eau à l’intérieur de troupeaux. Nous présentons les
résultats de plusieurs tests en situation réelle à travers l’Amérique Latine destinés à réduire la déprédation
du bétail dans les aires protégées et les terrains agricoles.
... Livestock owners experience varying degrees of loss, which could be influenced by factors such as the livestock species, how they are raised, and the behavior of predators (Baker et al. 2008;Peña-Mondragon et al. 2017). This is particularly true in areas where extensive meat production is a significant economic activity (Palmeira et al. 2015;Quigley et al. 2015;Ubiali et al. 2018). It is often assumed that felines are responsible for significant loss of livestock, disregarding other factors such as drought, disease, flooding, and starvation. ...
... Heterogeneous stakeholders require various management approaches that value their diverse interests and investment capacities (not only economic) (Hoogesteijn and Hoogesteijn 2014;Zimmermann et al. 2021). Methods to control livestock depredation by jaguars and pumas are extensively described elsewhere (Castaño-Uribe et al. 2016;Cavalcanti et al. 2012;Hoogesteijn et al. 2016b;Hoogesteijn and Hoogesteijn 2014;Quigley et al. 2015;Valderrama-Vasquez et al. 2017). Several studies (Baker et al. 2008;Krafte-Holland et al. 2018;Van Eeden et al. 2017;Van Eeden et al. 2018;and Wilkinson et al. 2020) have raised concerns over the efficiency and acceptance of methods employed to manage depredation and decrease financial losses, despite some degree of success. ...
... This experience is replicated in other situations (see Castaño-Uribe et al. 2016), where ranchers adopt more efficient animal husbandry techniques and keep up-to-date with the latest advances in tropical animal science. Ranches with more intensive management find it easier to implement methods to mitigate predation (Castaño-Uribe et al. 2016;Hoogesteijn and Chapman 1997;Quigley et al. 2015). Electric fences can be highly effective in various settings (Hoogesteijn et al. 2016b). ...

Livestock ranching overlaps extensively with jaguar and puma distribution in the Casanare Department of east-central Colombia. Conservation programs prioritize large carnivores in the region. Ranchers retaliate by killing them in response to economic losses or fear related to their presence. Reducing retaliatory hunting is a top priority in the conservation of feline species. Predation mitigation methods (PMMs) are necessary to reduce depredation and increase tolerance for large felines. In a prospective cohort study, 16 ranches between 2017 and 2019 used electric fences (n = 14) and introduced creole cattle (n = 2) as PMMs. There was a significant difference in the risk and odds ratios between the control and treatment groups. Livestock depredation was 14.78 times higher outside PMM areas (OR, 14.78; RR, 0.069; p < 0.001) than inside such areas. The losses caused by depredation were much higher than the investments made in PMMs.
... This is crucial, especially for recently modified Brazilian Forest Code legislation (Article 10, Lei 12.651/2012; Brasil, 2012) that decrees 50% forest cover must be maintained per ranch depending on the biome in which the ranch is located (in contrast to prior 1965 code Lei 4.771; Tomas et al., 2019). The ranches surveyed herein followed a mosaic model of conservation and included a variety of multi-use landscapes (working and protected; Quigley et al., 2015), with support for a local school and lucrative local ecotourism economy to offset financial losses due to livestock predation by jaguars . Ultimately, ranches that maintain an abundance of native prey species experience lower rates of cattle depredation Khorozyan et al., 2015;Polisar et al., 2003). ...
... Our study indicates that conservation efforts focused on protection of security cover and native prey base-the main drivers of predator density-can support long-term persistence of resident female (and, consequently, resident male) populations of a large carnivore. Lessons learned from our research and parallel activities include: (1) not persecuting wild predators Quigley et al., 2015); ...
... (3) implementing anti-predation techniques for vulnerable portions of the herd/ranched landscape (Cavalcanti et al., 2012;Ohrens et al., 2019;Quigley et al., 2015); (4) ensuring connectivity with intact habitat outside ranch boundaries, including adjacent or nearby protected areas/large patches of private protected forests for carnivore and wild prey persistence; and (5) offsetting costs through ecotourism or other valuation enterprises to diversify income and provide local benefits for maintaining wildlife ; see Appendix S1 for details). ...

Protected areas serve as population strongholds for many large carnivores, with multi‐use landscapes along their borders forming the front‐lines of wildlife conservation. Understanding large carnivore population dynamics within working landscapes is difficult where anthropogenic mortality is high and unregulated. This study focused on working ranches, where killing jaguars (Panthera onca) and their prey was prohibited, to gain insight into jaguar population potential across multi‐use landscapes. Faced with forest fragmentation, presence of domestic livestock, and dynamic land‐use practices, we expected jaguar populations in working landscapes to be predominantly male and transient, with low cub production, and inflated population densities in remnant forest patches, versus protected areas where we expected native forest habitat and stable jaguar territories. Using camera traps and spatial‐capture recapture analyses, we observed that male jaguars demonstrated larger‐scale movements and were more detectable than females (0.07 ± 0.01 SE vs. 0.02 ± 0.01 SE) in both working and protected landscapes. Female jaguars in ranches traveled farther than females in parks. Carnivore density increased with forest cover and wild prey activity, decreased with domestic prey activity, and was marginally higher in ranches (4.08 individuals/100 km2 ± 0.73 SE) than in parks (3.59 individuals/100 km2 ± 0.64 SE). Females outnumbered males in both landscapes (2.20–2.60 females/100 km2 vs. ~1.60 males/100 km2), although local male density reached up to 11.00 males/100 km2 in ranches (vs. 3.50 males/100 km2 in parks). While overall jaguar density was patchier in protected areas (x̿ = 0.69 parks, 0.54 ranches), inter‐annual patchiness was higher within ranches (Moran's I = 0.49–0.60 ranches, 0.69–0.70 parks), reflecting changes in cattle management. Despite major habitat alterations, working landscapes can support carnivore densities equivalent to (or exceeding that of) unmodified forest habitat, provided that wildlife‐tolerant ranching practices are maintained.
... Pumas, being less threatened, are less rigorously protected. However, the implementation of appropriate management practices in livestock production has been shown to reduce predation rates [17][18][19][20][21]. The use of electric fences, guard dogs, water buffalo, and control of calf birth periods are some of the conflict mitigation strategies that have been implemented across the region [19,21]. ...

... This management system often results in the occurrence of wildlife on the property, including jaguars and pumas, or livestock in areas inhabited by wildlife, making it difficult to implement measures to mitigate livestock predation [21]. In order to implement effective measures to mitigate the conflict between livestock farming and top predator conservation, several actions can be taken, including night confinement of livestock during periods of vulnerability, use of guard dogs, use of visual and acoustic repellants, and electric fences [18][19][20][21]. Simply fencing livestock out and away from forest cover, and riparian brush and forest areas would reduce depredation and help maintain stream and river quality. ...

Simple Summary Sustainable Development Goals for 2030 indicate that zero hunger (SDG 2) and halting biodiversity loss (SDG 15) are key priorities. Livestock management practices that allow coexistence with top predators are necessary to achieve both objectives in Latin America. This article addresses the situation in local indigenous communities near key biodiversity hotspots that protect top predators in Mesoamerica. Results show that livestock predation is related to landscape variables and human influence. Jaguar and puma conservation requires measures that facilitate human–carnivore coexistence and comply with SDG 2 and SDG 15. This study serves as a baseline to provide livestock management recommendations that mitigate the prevalent conflict with jaguars and pumas to reconcile SDG 2 with SDG 15. Abstract Livestock predation is a global problem and constitutes the main source of conflict between large carnivores and human interests. In Latin America, both jaguar and puma are known to prey on livestock, yet studies in Mesoamerica have been scattered and few have been carried out in Honduras. We interviewed ranchers in a biosphere reserve where jaguars and pumas are present. Local indigenous communities reported livestock predation (average annual loss of 7% from 2010–2019), with preventive and retaliatory killing as their main actions against predation by the jaguar and puma. Other sources of cattle loss included diseases and theft. The extensive management system (free grazing) lets cattle access forests where predators are more common. We found that livestock predation is not random, but rather, related to landscape variables and human influence. Sites farther from human influence and closer to forest cover were more susceptible to predation. Jaguar and puma persistence in the biosphere reserve will require measures that facilitate human–carnivore coexistence and comply with Sustainable Development Goals (SDG) 2 and 15 (zero hunger and biodiversity conservation). We propose management practices to mitigate livestock predation in the presence of large carnivores based on examples of proven human–carnivore coexistence in Venezuela, Brazil, Paraguay, and Nicaragua, such as improving the spatial arrangement of livestock (maintaining a distance from forest areas) and the incorporation of confinement pens for young calves (at least the first three months of life) and their mothers. If the pens are built close to the property’s house and have constant surveillance and/or dogs, the results are likely to be more effective. Deploying these proven tools may help change the current negative perception of ranchers towards large carnivores that is essential to conservation under the aims of SDG 15. We recommend government policies and support aimed to strengthen livestock health to increase productivity and to reduce their vulnerability to predation. Finally, this study represents a baseline to understand the magnitude of the human–carnivore conflict over cattle in one of the largest biosphere reserves in Mesoamerica.
... As shown in the conceptual model (Fig. 2), the cyclical relationship between economic pressures and predation risks often reinforces negative attitudes toward predators, leading to practices such as hunting predators for monetary rewards (Cavalcanti et al., 2010;Zarco-González et al., 2018). Implementing secure enclosures, electric fences, and surveillance grazing during high-risk hours in areas prone to carnivore predation could effectively reduce losses (Quigley et al., 2015). As such, efforts to manage predation should prioritize sheep farming, particularly in regions with a high incidence of puma predation. ...
... A positive perception of felines alone does not ensure tolerance for the losses incurred (Álvarez and Zapata-Ríos, 2022). Therefore, it is crucial to collaborate with ranchers to develop solutions that enhance their tolerance toward felines (Zarco-González, Monroy-Vilchis and Alaníz, 2013;Quigley et al., 2015). Additionally, incentives related to the welfare of livestock keepers should be considered, as these have been shown to positively impact livestockfeline coexistence (Kansky, 2022). ...

p> Background: The management of negative interactions between livestock farming and predators is complex because of the multifactorial and dynamic nature of the underlying causes, which include human elements that complicate their management. Previous studies have shown that modifications in livestock management practices can significantly reduce these interactions. Therefore, it is crucial to identify the factors that promote these negative interactions to develop effective management strategies. Objective: To diagnose livestock management practices and their relationship with predators, exploring how these practices influence predation events and farmers' capacity to manage them. Methodology: Interviews and surveys were conducted with livestock farmers to gather information on their socioeconomic characteristics, livestock management practices, and perceived losses. The qualitative approach captured farmers' perceptions and their relationship with predators on their farms, Results: The results suggest that the interactions between livestock farming and predators are influenced by management practices that increase predation events and by farmers' limited capacity to manage them. The location of farms in fragmented landscapes exacerbates this situation, indicating the need to strengthen farmers' capacities. The meaning of the livestock and dependence of ranchers on diverse activities hinder the implementation of new livestock management practices. Implications: The study identifies possible key strategies, such as forage banks, electric fences, and vaccination programs, to reduce predation risks and improve livestock farming sustainability. These strategies should consider the economic and cultural contexts of ranching communities for effective implementation. Conclusion: Ranchers' management decisions are strongly shaped by cultural and traditional factors. Including ranchers in the codesigning of conservation strategies, together with education and capacity-building, is essential for align conservation efforts with their values and needs to ensure long-term success.</p
... Protected areas play a crucial role in the conservation of jaguars Panthera onca as they provide essential resources such as prey, refuge, and water (Quigley et al., 2015). Despite jaguars' tendency to avoid humans, various threats, such as decreased in prey availability and habitat fragmentation, have forced the species to explore new territories beyond protected areas, bringing them closer to human settlements and increasing the chances of human-jaguar interactions Conde et al., 2010;Foster et al., 2010). ...
... Although a detailed proposal was submitted to the administration of Tortuguero National Park (ACTo -Tortuguero Conservation Area) at the beginning of 2022 (Arroyo-Arce et al., 2021), to our knowledge, it has not been approved to date. It is important to highlight that similar methods have proven effective deterrents to jaguars across the Americas (Cavalcanti et al., 2012;Quigley et al., 2015). ...

Human-wildlife interactions are on the rise due to anthropogenic pressures. Understanding these interactions is crucial for preventing conflict and promoting coexistence, ultimately benefitting humans and wildlife. In this study, we analysed the interactions between humans and jaguars Panthera onca in Tortuguero National Park, Costa Rica. We examined data concerning jaguar sightings within Tortuguero National Park, Costa Rica compiled from 2000 to 2022. A total of 381 jaguar sightings were recorded, of which 75% occurred in the coastal habitat; 81% occurred during the leatherback sea turtle Dermochelys coriacea (March-May) and the green sea turtle Chelonia mydas (June-October) nesting seasons. From photographic records, 26 individual jaguars were identified (14 females, 12 males). Furthermore, 9% of the sightings were reported within the boundaries of Tortuguero village, where at least 48 domestic dogs Canis lupus familiaris were attacked by jaguars. Despite the jaguar's cryptic nature, the data show an increase in the frequency and duration of jaguar sightings over the years. This trend is likely due to an increase in the local jaguar population and possibly an increase in jaguars' tolerance towards humans, possibly triggered by people's inappropriate behaviour (e.g. approaching jaguars while feeding, mating or with their cubs) during the sightings. Our study also highlights the potential for conflict due to jaguar predation of domestic dogs, which is increasing within the study area. Therefore, there is a need for management action to promote coexistence between humans and the local jaguar population in Tortuguero National Park, Costa Rica.
... Most management has been reactive to multiple causes of hunting and poaching. The most evident and widespread management has been indirect, consisting of improved livestock husbandry to prevent attacks on livestock and domestic animals (Castaño- , Hoogesteijn & Hoogesteijn 2010, Hoogesteijn & Chapman 1997, Jędrzejewski et al. 2017, Quigley et al. 2015. It merits mentioning that techniques have now been developed that span the spectrum of livestock operations from small farms embedded in forests (pigs and cows), to much larger commercial operations and across nearly all biomes where the species occurs (Valder rama-Vasquez et al. 2024). ...
... It merits mentioning that techniques have now been developed that span the spectrum of livestock operations from small farms embedded in forests (pigs and cows), to much larger commercial operations and across nearly all biomes where the species occurs (Valder rama-Vasquez et al. 2024). There has been enough characterisation of attacks on cattle, and currently the need is to further the understanding of efficacy of the solutions across the spectrum of operations and settings (Hoogesteijn & Hoogesteijn 2011, Hoogesteijn & Hoogesteijn 2013, Quigley et al. 2015, Villal ba et al. 2016, Valderrama Vásquez et al. 2017). ...

The jaguar Panthera onca is widely distributed throughout South America with its stronghold in the Amazon. It is protected by law in all countries, but some countries have legal loopholes and all lack a strict enforcement of the laws in place. Jaguar killing is common, even in strictly protected areas, but detailed records are lacking. Jaguars have been historically hunted for their pelts, however, inclusion of the species in the CITES Appendix I proved effective to curtail the spotted cat trade in the 1960s and 70s. Over the last few decades, there exists little information on jaguar hunting for trade, but recently reports have surfaced showing increased illegal trafficking of body parts with evidence of domestic and Asiatic demand. Conservation of jaguars in South America has been relatively well-informed by research data. National parks and indigenous lands have been and still are the cornerstones for jaguar conservation throughout the continent, but are hampered, with a few exceptions, by underfunding, understaffing and a lack of governance and political will. Financing the operation of national parks and protected areas, while securing rights of indigenous lands should be a priority for funding agencies, especially in areas where most jaguar populations are restricted to protected areas like Argentina and south-eastern Brazil. In countries where jaguars are still widespread efforts should also be directed toward unprotected areas where threats like habitat loss and killing are higher. There the biggest management challenge is upscaling conflict prevention and mitigation measures. The Jaguar 2030 Roadmap marks a milestone for the species, aiming to join range governments, NGOs and private partners to advance conservation action for jaguars, but getting the initiative off the ground is the current challenge. It is noteworthy to highlight the importance and need for transboundary cooperation and action, especially among the trans-frontier population hotspots. The new, or emerging threats like jaguar part smuggling and man-made fires need extra attention and action to be curtailed. If jaguar conservation is to be effective despite increasing threats, it needs to be streamlined from high level agreements through scalable effects on the ground, combining protected areas, corridors, and local people buy-in.
... We constructed a "threat index" (TI) applied to each of the 447 protected areas using the above geospatial layers for both each PA ( in ) and each respective buffer polygon ( out ), which are weighted according to specialized literature on jaguar threats (see refs. 4,16,23,25,49,[91][92][93][94][95]. For instance, the major causes of jaguar declines is a synergistic effect of habitat loss, fragmentation, and killings (generally linked to human population density) (e.g., ref. 23 , ref. 91 , ref. 92 , ref. 93 , ref. 94 ), therefore, these variables received the largest weight in our TI, whose sum can be larger than 1.0 due to synergetic effect upon mammal populations 93 . ...

Jaguars (Panthera onca) exert critical top-down control over large vertebrates across the Neotropics. Yet, this iconic species have been declining due to multiple threats, such as habitat loss and hunting, which are rapidly increasing across the New World tropics. Based on geospatial layers, we extracted socio-environmental variables for 447 protected areas across the Brazilian Amazon to identify those that merit short-term high-priority efforts to maximize jaguar persistence. Data were analyzed using descriptive statistics and comparisons of measures of central tendency. Our results reveal that areas containing the largest jaguar densities and the largest estimated population sizes are precisely among those confronting most anthropogenic threats. Jaguars are threatened in the world’s largest tropical forest biome by deforestation associated with anthropogenic fires, and the subsequent establishment of pastures. By contrasting the highest threats with the highest jaguar population sizes in a bivariate plot, we provide a shortlist of the top-10 protected areas that should be prioritized for immediate jaguar conservation efforts and 74 for short-term action. Many of these are located at the deforestation frontier or in important boundaries with neighboring countries (e.g., Peruvian, Colombian and Venezuelan Amazon). The predicament of a safe future for jaguars can only be ensured if protected areas persist and resist downgrading and downsizing due to both external anthropogenic threats and geopolitical pressures (e.g., infrastructure development and frail law enforcement).
... Ranchers should also implement modified grazing practices and management such as housing newborn calves in maternity paddocks to reduce depredation risk (Hoogesteijn & Hoogesteijn, 2011). The application of control measures and antipredatory strategies can improve livestock production, supporting changes in the perception towards felids and sustainable management of productive systems, thus allowing the tolerance of areas of coexistence and conservation of big cats (Quigley et al., 2015). This is why alternatives and solutions for the inclusion and participation of producers in the conservation plans of these species is fundamental to mitigate the negative impacts on the populations of large carnivores and on local livelihoods (Hoogesteijn & Chapman, 1997;García-Anleu et al., 2016). ...

La prevención y mitigación de los conflictos con el hombre son prioritarias para la conservación de los grandes carnívoros. La caza por venganza tras la depredación del ganado es una de las principales amenazas para el jaguar (Panthera onca) y el puma (Puma concolor) en América. Se consultaron registros de informes gubernamentales, agencias de recursos naturales, medios de comunicación y observaciones de campo para caracterizar el conflicto entre humanos y grandes felinos en el Parque Nacional Natural Paramillo de Colombia. Entre 2007 y 2022, se reportaron 37 eventos de depredación de grandes felinos sobre perros domésticos y ganado, de los cuales el 84 % correspondió a ataques de jaguares. Se encontró que los animales más depredados, en orden de ataques, fueron cerdos, perros, ovejas y vacas. Los excesos de matanza (es decir, > 1 animal atacado en un evento de depredación) representaron el 61 % de todos los eventos de depredación. Los principales obstáculos para el manejo son la insuficiencia de personal para verificar la depredación y la falta de protocolos operativos claros. Finalmente, se identifican estrategias para reducir el riesgo de depredación y mejorar la gestión actual.
... Conservation education conducted at the grammar school level is an effective way of lowering acceptance of killing protected species in rural areas (Baruch-Mordo et al. 2011, Marchini & Macdonald 2012, St. John et al. 2015, Engel et al. 2016. Education aimed at improving husbandry practices and implementation of protective methods that can reduce rates of cattle predation by jaguars (Hoogesteijn & Hoogesteijn 2010, Quigley et al. 2015, Castaño Uribe et al. 2016) is important in areas where jaguar range and cattle production are overlapping, e.g. in Colombian and Venezuelan Llanos, the Llanos de Moxos in Bolivia, as well as several lower elevations in the Andes and in Brazilian Amazon (SOM Table T2). A key factor for success in achieving all of these goals is international cooperation, especially important for monitoring jaguar popula-tions and controlling illegal trade. ...

We analysed the current conservation status of the jaguar Panthera onca in north- western South America (7.14 million km2 in total). The area is composed of habitats belonging to three eco-regions: the Andes, the Llanos, and the Amazon. Based on a large set of jaguar presence-absence data and a species distribution model, we estimated the current jaguar range at 4.98 million km2, which represents 78.6% of the historical jaguar range in this region. The countries where jaguar range has shrunk most are north-western Venezuela, Ecuador and Colombia. Across the region, protected areas cover 27% of the jaguar range and indigenous territories 25%, with Ecuador having the highest and north-west Venezuela the lowest percentage of jaguar range under protection. Jaguar densities vary across the region, from 0.3 jaguars/100 km2 in the driest or most degraded parts to 4.0–7.3 jaguars/100 km2 in humid, productive, and best- preserved habitats of the Amazon Basin and Venezuelan Llanos. Based on combined density and updated distribution models we estimate a total jaguar population at 105,000 jaguars (95% CRI: 81,200–128,800) for the region, with mean density of 2.1 jaguars/100 km2. Jaguar diet varies by habitat, from arboreal mammals and aquatic reptiles (mainly caimans) in the ‘varzea’ floodplain forests of Central Amazon, to large and medium- sized mammals in upland tropical forests and in the Llanos, with peccaries, capybaras, and occasionally livestock being the most important prey species. The main threats for jaguars in the region are deforestation and fragmentation of habitats, human-jaguar conflict, poaching (increasing due to the growing demand for jaguar parts from the Asian market), infrastructure expansion, and mining. The most important conservation goals are to halt deforestation, reduce the killing of jaguars for retaliation and trade, increase the number of protected areas, protect ecological connectivity, improve law enforcement, and implement a better system of environmental education.
... As many authors suggest, to reduce the negative impacts of wildlife, it is necessary to change the way owners manage their animals (Escobedo 2011;Hoogesteijn and Hoogesteijn 2014;Nyhus 2016;Polisar et al. 2003, Quigley et al. 2015. This study area, like many others in the world, is important for wildlife conservation because there is structural connectivity between wildlife and the cultural values and traditions of indigenous people that are also important to conserve. ...

Sáenz-Bolaños C, Fuller TK, Sievert L, Carrillo E. 2022. Human-wildlife conflict in indigenous communities of the Nairi Awari Indigenous Territory of East Central Costa Rica. Biodiversitas 23: 2238-2244. Human-wildlife conflict is essential for conservation because it is necessary to maintain the balance of requirements needed by humans and wildlife. Indigenous territories are not exempt from interactions with wildlife, and in this study, we focus on one indigenous territory of the Cabécar Indigenous Group of Costa Rica called Nairi Awari. We wanted to know which are the most common wildlife species, which interactions with these species the Nairi Awari consider negative, and what are the possible solutions to these interactions. To do this, we administered 24 semi-structured questionnaires to indigenous people from March-August 2019. The results showed 16 species as “problematic animals”, the jaguar (Panthera onca) being the most common, followed by hawks. Of the six problem categories identified, predation on poultry was the most cited category, but it raised fewer negative feelings among respondents than some other problems. Possible solutions to pig or cow predation, problems which most maddened respondents, included improved management (48%), scaring animals (12%), and killing big cats (16%). It is important to understand these perceptions in order to address future management to benefit conservation and human welfare. In particular, there is potential to work in the long term to improve the management of domestic animals.

As large predators, jaguars (Panthera onca) require vast expanses of well conservedland, abundant prey and few people. This study reviews three different ecological studieson jaguars living in unprotected lands. The first study focuses on Colombian jaguarsliving with indigenous peoples in Amazonia, while the second study examines aColombian jaguar population living in cattle ranches persecuted for depredation. Thethird study concerns jaguars surviving in the Rupununi savannahs of Guyana, wherecattle ranching is withering and tourism is gaining ground. All examples have five maincommon factors that enable jaguars to survive in unprotected lands: low human density,poor soils, inaccessibility, wild prey availability and closeness to large protected areas (>3,000 km2). We propose that the long-term conservation of jaguars will depend onconserving populations in unprotected lands as a complement to protected areas.

The conflict caused by large carnivore attacks on livestock constitutes a major threat to the conservation of carnivore species worldwide. The objective of this study was to determine what factors influence jaguar Panthera onca and puma Puma concolor attacks on cattle at a ranch in the Brazilian Pantanal. Cattle herds were monitored for 57 months, and data were collected for each recorded mortality event. The economic impact of predation was calculated. We parameterize a generalized linear model with negative binomial error distribution to model the influence of water levels of the Paraguay River, size of cattle herd and the age structure of the herd on the monthly number of cattle killed by big cats. Over half of all recorded herd mortality events were caused by large cat predation, resulting in a maximum 2.83% of the average annual herd size and representing an annual financial loss of US$22 400.00. A positive relationship was found between the frequency of monthly attacks and the water level of the Paraguay River, whereas a negative relationship was found between monthly attacks and proportion of adult cattle in the herd. Juveniles were taken more frequently than adults. Increased water levels caused the herd to concentrate on higher ground usually near forested areas, suggesting an increase in cattle vulnerability to predation. A greater proportion of adults in the herd may also increase the possibility for defensive behavior, likely resulting in greater protection of younger cattle. Understanding the factors that predispose cattle to predation by big cats contributes to the establishment of management strategies that may reduce losses and, ultimately, conflict.

The jaguar is one of the most mysterious and least-known big cats of the world. The largest cat in the Americas, it has survived an onslaught of environmental and human threats partly because of an evolutionary history unique among wild felines, but also because of a power and indomitable spirit so strong, the jaguar has shaped indigenous cultures and the beliefs of early civilizations on two continents. In An Indomitable Beast: The Remarkable Journey of the Jaguar, big-cat expert Alan Rabinowitz shares his own personal journey to conserve a species that, despite its past resilience, is now on a slide toward extinction if something is not done to preserve the pathways it prowls through an ever-changing, ever-shifting landscape dominated by humans. Rabinowitz reveals how he learned from newly available genetic data that the jaguar was a single species connected genetically throughout its entire range from Mexico to Argentina, making it unique among all other large carnivores in the world. In a mix of personal discovery and scientific inquiry, he sweeps his readers deep into the realm of the jaguar, offering fascinating accounts from the field. Enhanced with maps, tables, and color plates, An Indomitable Beast brings important new research to life for scientists, anthropologists, and animal lovers alike. This book is not only about jaguars, but also about tenacity and survival. From the jaguar we can learn better strategies for saving other species and also how to save ourselves when faced with immediate and long-term catastrophic changes to our environment.

The killing of jaguars by ranchers in Amazonia and the Pantanal is a major threat to the species. We used the Theory of Planned Behavior to examine the role of ranchers' perceptions, norms, attitudes and intentions concerning jaguar killing, in determining their jaguar-killing behavior. We also investigated the influence of: (1) descriptive norm and social identity on ranchers' intention to kill jaguars on their properties ; and (2) the effect of perceptions of jaguar impact on human livelihoods (livestock and human safety), and of property size, on the variables that influence intention to kill. Results based on interviews with 268 cattle ranchers indicated that the impact of jaguars on livestock is not the only predictor of a rancher's intention to kill jaguars. Fear, personal and social motivations, and internal and external barriers (e.g. lack of skills and force of law, respectively) to killing jaguars can also influence jaguar killing. The relative importance of these factors in determining intention to kill varies with region and affluence. We recommend ways of deterring jaguar killing behavior through communication interventions. In addition to the economic and legal incentives that have already been considered by conservationists, effective strategies to protect jaguars on privately owned land will need to address the social and psychological factors that determine the killing of jaguars by ranchers. Conservationists need to find and support ways to make jaguar killing not only unprofitable and illegal, but also socially and personally unacceptable.
