Poisoning of endangered Ara-
bian leopard in Saudi Arabia
and its conservation efforts
Many killings of leopards can be attributed to livestock protection. When catching
goats, sheep, young camels or other domestic animals, leopards interfere with hu-
man activities and are seen as straight competitors. With the decrease of natural
prey species, they have to more and more shift their diet to livestock, which increas-
es their unpopularity. In most cases, they are also considered as a threat for human.
As a result, leopard is hunted across its range, with different methods (trapping, poi-
soning, shooting). Poisoning using anticoagulant rat killer was common in the eight-
ies, which was stopped in 1985 unlike trapping. A total of only five known incidences
of poisoning of Arabian leopards Panthera pardus nimr have been recorded in Saudi
Arabia between 1965 and 2014. Shepherds poisoned the carcasses of sheep, goats,
camel thought to have been killed by a predator such as Arabian wolf Canis lupus
arabs, striped hyena Hyaena hyaena or stray dogs and unfortunately, the predator in
these instances was the elusive Arabian leopard.
The Arabian leopard is Saudi Arabia’s flag-
ship predator and is listed as Critically En-
dangered by the IUCN (Mallon et al. 2008,
Boug et al. 2009, Islam et al. 2011), with an
effective population of 100-250 across its en-
tire range in the Arabian Peninsula (Islam et
al. 2011). It is also considered to be a geneti-
cally distinct subspecies (Mallon et al. 2008).
Known locally as Al nimr al-arabi, this leop-
ard subspecies is small, adapted to desert
habitats and endemic to the Arabian Penin-
sula. It once occupied the mountainous rim of
the Arabian Peninsula, albeit at low densities
given the harsh environment and limited prey
base (Fig. 1).
Historically much of the leopard’s range was
located within the Kingdom of Saudi Arabia
(Fig. 1), which decreased by about 90% since
the 19th Century (Judas et al. 2006, Boug et
al. 2009). Primary threats to the species are
habitat degradation and fragmentation re-
sulting from road or track construction (and
which facilitate access for poachers), over-
grazing by sheep and goats, construction of
new houses (especially in rural areas), urban-
ization along the Asir Range on the Biljurashi
Plateau, and mining or gravel extraction de-
velopment. Depletion of the leopard’s prey
base and retributive killing are the greatest
threats. Excessive illegal hunting has greatly
depleted key prey populations like the Nubian
ibex Capra nubiana, Hyrax Procavia capensis,
and Cape hare Lepus capensis (Al Johany
2007). As a consequence, the leopard has be-
come increasingly dependent upon domestic
stock for its subsistence, in turn leading to
retaliation by those herders losing animals.
Carcasses are poisoned and traps set to kill
the predator whenever it is encountered (Ju-
das et al. 2006). Although legally protected,
the current law enforcement is ineffective (Al
Johany 2007, Judas et al. 2006). Finally, there
are reports of the sale of furs and rarely live
animals sold in the market. For example one
cat was sold for $4,800 in the Al Khawbah
market in 1997 (Judas et al. 2006). Leopard
fat is valued by some locals for its perceived
medicinal properties (Judas et al. 2006).
Incidences of leopard poisoning
A total of only five known incidences of
poisoning of Arabian leopards have been
recorded in Saudi Arabia between 1965 and
2014 (Fig. 1, Table 1). Shepherds poisoned the
carcasses of sheep, goats, camel thought to
have been killed by a predator such as Ara-
bian wolf, striped hyena or stray dogs. Unfor-
tunately, the predator in these instances was
the elusive Arabian leopard (Fig. 2).
One of the first known poisoned leopards was
in Fiqrah mountain in Hijaz range in Madinah
province, where one leopard was found dead
in 1992; the Saudi Wildlife Authority team
investigated and confirmed the carcass was
a leopard (A. Boug, pers. comm.). Al Johany
(2007) interviewed local people who con-
firmed the presence of leopard some decades
before in the Jabal Radwa. The Fiqrah moun-
tain which is at about 1,800 m is barren and
sparsly vegetated. Recent camera trap studies
have confirmed the presence of wolf, striped
hyena, Blanford’s fox Vulpes cana, honey
badger Mellivora capensis, honey collectors
and hunters (Jackson et al. 2010).
The second site is An Namas in the South-
western Highlands in Asir mountain, which
was identified as a globally important bio-
diversity hotspots by Conservation Interna-
tional. The hills are above 2,000 m and the
vegetation is dominated by thick juniper for-
est and rich in animal diversity that include
Nubian ibex, mountain gazelles Gazelle ga-
zella cora, hyraxes, Blanford’s fox and red
foxes Vulpes vulpes, caracal Caracal caracal,
Arabian wolves, striped hyenas and Arabian
leopard (Nader 1996, Jackson et al. 2010).
The carcasses of two leopards were found
in January 2007. Since 2010, more than 70

camera traps were installed in An Namas and
nearby areas.
Bani Saad was the third site where a male
leopard was found dead in April 2011. The
site is 65 km from Taif city in the south, where
25 camera traps were installed and key spe-
cies recorded were Arabian wolves, striped
hyenas, caracal Caracal caracal and foxes as
well as local people and honey collectors.
A male leopard was found dead at the fourth
site, Wadi Al-Nauman village near Al Hada,
Taif. The complete skin along with head of
the leopard was obtained on 23 February
2014 and 30 camera traps were installed
in the mountains. Besides people, Arabian
wolves, striped hyenas, honey badgers and
Blanford’s fox were pictured.
Poisoning of Arabian leopard in Saudi Arabia
According to the wildlife laws of the coun-
try, it is illegal to poison or threatened any
animal. In the cases mentioned above, shep-
herds found dead livestock and poisoned
them to reduce the incidence of livestock
depredation. On finding the dead leopards,
the shepherds were surprised as they ex-
pected wolves or stray dogs and were not
aware of the presence of leopards in those
areas. These incidents were acts of blind kill-
ing because shepherds were not targeting a
specific species.
Saudi Wildlife Authority is working hard to
save the Arabian leopard from extinction
through a three-pronged initiative (Islam et al.
2011): (1) the captive breeding program where
the National Wildlife Research Centre NWRC
has 11 leopards (Boug et al. 2009); (2) mea-
sures involving research and wildlife studies
including workshops, to learn more about the
Arabian leopard and identify ways and means
to protect it. This includes installing infra-red
camera traps to monitor them and their move-
ments; and (3) Public awareness where the
National Wildlife Authority with its National
Wildlife Research Center based in Taif visits
schools, universities and other educational
institutions to spread awareness about this
Critically Endangered cat.

The Critically Endangered Arabian Leopard (Panthera pardus nimr) has declined to near extinction in Saudi Arabia over the last fifteen or so years. In this paper we provide a time-series assessment of changes in the rate of leopard records since the 1930’s and provide a values-based plan for the management of the species in Saudi Arabia. The number of leopard records rose sharply in the 1960’s, peaking in the early 2000s, a time where human population growth and expansion across Saudi Arabia was also increasing. However, by 2014, the number of leopard records decreased to zero where it has remained. Based upon a clear need for effective conservation of the species, we developed a values-based management plan. In applying the planning framework, we defined the management system and its elements in their current state and the required state by the year 2050. From this work, a value-based goal was established, and four key management activities were recognised (and are expanded upon in the main text). We recommend that work is done to: (1) Ensure sufficient and suitable (in terms of required habitat and prey availability) areas are protected. (2) Reduce the level of human-based predation upon leopards to ensure sustainable mortality rates. (3) Manage the species metapopulation structure in terms of genetic makeup through natural and/or facilitated movement. (4) Continue to build community capacity and willingness to manage and protect the species. If these activities can be successfully completed, a population of Arabian Leopards can exist in Saudi Arabia if it is adaptively managed to deal with any additional and/or emerging threatening processes.
... Tourism development may also constrain and further fragment Blanford's fox populations in the country. Hunting, poisoning Islam et al., 2014), and adverse interactions with more abundant carnivores such as feral dogs (Canis lupus familiaris), red foxes and Arabian wolves (Canis lupus arabs) may also contribute to their decline . Previous observations suggest that lethal interactions between Blanford's foxes and Arabian wildcats (Felis lybica lybica) may occur (Faure et al., 2021). ...
... However, these areas were subjected to extensive pastoralism, and consequently human-carnivore conflict ). Human-carnivore conflict often results in indiscriminate predator control methods, such as poisoning and cage trapping (Islam et al., 2014) being used which can affect numerous non-target species. In addition, urban development in mountainous areas further threatens their populations as roads are built into previously inaccessible areas, increasing the risk of road collisions as well as accessibility for hunters and other anthropogenic-related disturbances (Alagaili et al., 2011). ...

The Blanford's fox (Vulpes cana) is a small canid species classified as Least Concern by the IUCN Red List. They predominantly inhabit mountainous regions in arid ecosystems across the Arabian Peninsula, Central Asia and North Africa. In the Kingdom of Saudi Arabia (KSA), the species has been recorded only in limited localities and its population is believed to be in decline. We present data from camera trapping surveys conducted between March 2020 and December 2022 to update and confirm the species' known distribution in KSA. We captured 470 independent captures of Blanford's fox at 21 survey sites, representing 191 spatially independent locations. We used ensemble species distribution modelling to predict areas of suitable habitat within their IUCN Red List distribution range. Our results suggest that the most favourable habitats for the Blanford's fox in KSA are in the rugged, mountainous areas along the southwestern Asir range. These findings provide insights into the species' distribution and may support future conservation efforts to maintain viable populations of Blanford's fox in KSA.
... Fragmentation from urbanisation and roads, and degradation from construction, mining, and gravel extraction contribute to habitat deterioration and decreases in leopard populations (Judas et al., 2006;Islam et al., 2017Islam et al., , 2018. Despite being legally protected across their range, illegal hunting, trapping, and poisoning are also a significant factor in declining leopard numbers (Islam, Boug, As-Shehri, & Al Jaid, 2015;2018). While there are no official records of the level of leopard poaching, 52 individuals were confirmed to have been killed since 1883 (Islam et al., 2018), demonstrating that there is historical leopard hunting in the region. ...
... In Oman, leopards hunt prey such as Arabian gazelle (Gazella arabica), Nubian ibex (Capra nubiana), Cape hare (Lepus capensis), and rock hyrax (Procavia capensis) (Muir-Wright, 1999) but in Saudi Arabia overgrazing by domestic animals such as sheep, goats, donkeys and camels, alongside poaching for meat has led to a rapid decline in wild prey species (Islam et al., 2018). Under these circumstances, leopards commonly prey upon domestic livestock and consequentially evoke retaliatory killings by herders, expediting their population decline (Islam et al., 2015). Understanding these environmental, biological, and anthropogenic factors that affect Arabian leopard habitat suitability is critical to inform species survival strategies and distribution mapping. ...

Camera trapping can detect and monitor rare species in landscapes spanning thousands of square kilometres but placement of cameras in areas where the animals most likely occur will increase detection success. This vital information is lacking for the critically endangered Arabian leopard (Panthera pardus nimr) that has undergone a 90% decline across its range in Saudi Arabia. We aimed to identify suitable Arabian leopard habitat and potential population capacity in Saudi Arabia using data from leopards living in ecologically analogous habitat in South Africa and Oman. We developed a resource selection function (RSF) from 14 leopards’ GPS data in the Cederberg, South Africa, and validated the model using three leopards in the Little Karoo, and two Arabian leopards in Oman. We then projected the model to the historical range of Arabian leopards in Saudi Arabia to estimate likely leopard locations and potential population sizes based on home range metrics. The RSF successfully discriminated between used and available locations (specificity=96.7%) and had high predictive ability (Rho>0.9). Leopards selectively used areas away from human settlements and roads, with high enhanced vegetation index, and intermediate slopes and elevations. Saudi Arabia could theoretically host 4 distinct populations totalling 162-362 Arabian leopard females, depending on home range size. Camera traps deployed in the south-western mountains of Saudi Arabia may be most likely to detect remnant populations of Arabian leopards. Further research is needed into the local abundance of prey species and human activity to ensure the persistence of suitable leopard ranges and inform conservation actions.
... The International Union for Conservation of Nature (IUCN) documents that out of the eight subspecies of leopard (Panthera pardus), the majority are listed as Endangered or Critically Endangered (Kitchener et al. 2017;Jacobson et al. 2016). Of these subspecies, the Arabian Leopard Panthera pardus nimr is listed as Critically Endangered (Mallon et al., 2008), where its population size has been estimated at 150-200 across its entire range in the Arabian Peninsula Spalton & Al Hikmani, 2014;Breitenmoser et al., 2006;Islam et al., 2015;2018). This is the smallest leopard subspecies well adapted to desert habitats in the Arabian Peninsula. ...
... Sets of presences and absences used to train our distribution model were far apart: presences in Oman and absences in western Saudi Arabia. However, we do not think that the geographic gap between the samples might affect the ecological sense and usefulness of our model, given that both sets of locations are parts of the species distribution range (Breitenmoser et al., 2006;Mallon et al., 2008;Islam et al. 2015;2018). Initial analyses to cover this spatial gap and derive distribution models using either all or various subsets of 256 confirmed historical presence records via both presence-only and presence/absence methods showed much poorer results than those based on our training presence/absence locations. ...

This study attempts to link the distribution and movement rate of the critically endangered Arabian Leopard (Panthera pardus nimr) to environmental and anthropogenic features, and to identify environmental constraints and priority areas for the recovery of leopard in Arabian Peninsula. Generalized linear and additive models were used to fit leopard presence/absence locations to environmental and anthropogenic variables. Movement rates between the polygons of modeled leopard presence were inferred and mapped using the isolation-by-resistance model, where probability values of the species distribution model were treated as those of conductance. Our results suggest that currently the Arabian Leopard prefers to live and move in terrain that has high values of normalized difference vegetation index (NDVI) and is difficult for humans to reach. The current network of protected areas largely under-represents the species suitable habitat only covering its 11%, and most of the survey effort to detect and ensure the survival of the leopard in the peninsula has taken place outside the polygons identified by our models as core areas for the species. Our models coupled with existing data suggest the following scenario of the species biogeography: The Arabian Leopard accumulated genetic and phenotypic differences from its conspecifics at a series of glacial maxima during the last glacial period in the Yemeni refugium, from where it expanded elsewhere in the Holocene warming following the expansion of suitable landscape types. Humans expanded too, eventually restricting the source populations of the leopard to an area intersecting eastern Yemen and western Oman today. Our models may serve as a tool for planning future research and conservation for Arabian Leopard.
... Historically, the Arabian leopard roamed diverse regions from the Sinai Peninsula in Egypt, through Israel, the West Bank, and Jordan, all the way to the mountainous areas of Saudi Arabia, Yemen, Oman, and the UAE (Jacobson et al., 2016;Spalton, and al Hikmani, 2006). However, since the 19th century, its range has been more than decimated, primarily due to habitat loss and fragmentation caused by human encroachment, declining prey populations, as well as direct hunting, retaliatory killings provoked by livestock losses, and poisoning (Jacobson et al., 2016;Islam et al., 2015Islam et al., , 2018Breitenmoser et al., 2006). ...

The Arabian leopard (Panthera pardus nimr) has experienced dramatic range and population contractions over the last century. Conservation efforts for this felid focused on captive breeding and identification of suitable conditions for reintroductions. With this study, we unravelled historical collaring and direct observations data to understand the spatial use of the last leopards recorded in the region of Israel and the West Bank (IWB). Through datasets of leopard occurrence, we characterised suitable habitats, assessed niche overlap with the Arabian leopard's main prey, the Nubian ibex (Capra nubiana), and evaluated their distributions with respect to currently protected habitats. We estimated home-ranges employing area-corrected density kernel methods and investigated suitable conditions through multiple scales habitat modelling. Average home ranges for the population were 73.24 ± 47.91 km2 and 77.46 ± 54.94 km2, depending on the time lag adopted. Ecological response to predictors highlighted reliance by both predator and prey on the same habitat characteristics, suggesting they occupied essentially identical niches. These characteristics were intermediately rugged topographic conditions and high indices of vegetation in scarcely populated desert environments, mostly encompassed within protected areas. The distribution of leopard and ibex overlapped substantially according to several metrics. Notably, more than half of potential habitat for both species is encompassed by protected areas and military zones. Given the coincidence in their ecological requirements, and highly congruent distributions, an important step towards future reintroduction of Arabian leopards will include gaining a better understanding of ibex populations, alongside attention to the practicality of enforcing habitat protection.
... The humancarnivore battle is a common issue, and this is due to leopards' proteinrich diet [115] . Species undergo a high risk since in many landscapes of the NCL, no matter whether livestock offtake due to leopards is low, they may become victims even when there was attack by other carnivores, specifically if poisoning is used as leopards will scavenge their prey [180,181] . Some herders knew the NCL's habit of coming back to eat unfinished prey in Heshun County, and a few leopards have died of poisoning in this area [132] . ...

Carnivores have always undergone interspecific and intraspecific threats that seem tough to detect since carnivore studies often rely on passive sampling when investigating spatiotemporal threats or interactions with human activities. Studies on carnivores’ niche have been an important ecological topic for a long time as carnivore species are crucial in the functioning of ecosystems. This study focused on analysing the coexistence patterns of the North China leopard (Panthera pardus japonensis), the leopard cat (Prionailurus bengalensis) and the red fox (Vulpes vulpes) in a human-dominated landscape, the Tieqiaoshan Natural Reserve (TNR), and to provide insights for implications of carnivores conservation. The objectives of the study were: 1) to make insights on the North China leopard in distribution, threats, conservation and population status; 2) to characterize the spatiotemporal coexistence of the North China leopard, the leopard cat and the red fox in one season of data collection and depict effects of environmental factors on species’ site occupation; 3) to make a multi-year assessment of occupancy, detection and coexistence across three years and evaluate anthropogenic disturbances on carnivores estimates; 4) to analyse the threats of invasive species, including humans, livestock, and domestic dogs, on native carnivore in spatiotemporal patterns. We used the documentary method to bring out results related to the first objective. For the three remaining objectives, in the spatial patterns, we performed the occupancy models, the single-season single-species and single-season two species (where 589 independent photographs from 81 camera traps were analysed), multi-season single-species and multi-season two species (where 81, 62 and 62 camera traps were respectively used in season one, two and three, with 589, 496 and 472 independent photographs respectively) from 2017 to 2019. We estimated three carnivores' site occupation, the environmental factors’ and human disturbances effect on species’ occupancy and detectability. In the last objective, we also estimated the site occupation of invasive species (humans, livestock, and domestic dogs). On the other hand, we calculated the temporal overlap between species using the Kernel Density Estimate through the overlap package in the temporal patterns. The mainly results of this study are followings: 1) We suggested that the North China leopard's current distribution has drastically changed and only 2 % of its historical distribution remains occupied. Extant patches are in continual danger as the proximity index of patches was small which implying lack of connectivity. Habitat fragmentation, retaliation, and decline in prey species are the main threats. However, there is hope in conservation and long term existence in the area for this leopard sub-species for its survival because new management policies are being undertaken and will eradicate or reduce threats. 2) Our study revealed extensive and simultaneous presence, implying high overlapping for space and activities during a broad time period (dawn-morning, and crepuscular) between fox and leopard. The North China leopard and the leopard cat avoided each other. The leopard cat and the red fox independently co-occurred with an overlap in nocturnal time. There was true coexistence between the North China leopard and the red fox. The vegetation continuous cover degree was found to be the most important factor in candidate models for site occupation. 3) In a multi-year pattern, the North China leopard occupancy probability did not markedly change with time as the occupancy equilibrium was constant or slightly enhanced. The occupancy of the leopard cat decreased with time. The occupancy equilibrium of the red fox alternately increased and decreased. However, all species presented a slight level of occupancy stability due to their small values of rate of change in occupancy. Environmental factors and anthropogenic disturbances slightly influenced the occupancy of all species across the years. The colonisation and local extinction for all species were relatively more strongly affected by the distances to villages and roads. Moreover, elevation increased the colonisation and decreased the extinction of the leopard cat. Species interaction factors increased with time for all species. 4) In the invasive and carnivore species’ encroachement, the invasive species did not show substantial changes in the occupancy rate and were well detected. Still, invasive species depicted higher values of occupancy equilibrium than carnivores in both interseasons. Domestic dogs directly co-occur with native carnivores (SIF > 1) while humans and livestock presence have direct (SIF > 1) and indirect (SIF not very high than 1) co-occurrence respectively with the North China leopard and leopard cat and red fox. The leopard cat was the least spatially affected carnivore by the invasive species interactions. In temporal patterns, the North China leopard depicted real temporal activities overlap (high Δ4) with all invasive species compared with the leopard cat and red fox (low Δ4). 5) This research confirmed that environmental factors and human perturbations are vital factors to wild carnivores' coexistence. It also exposes the negative impact of free-ranging invasive species across this protected area on native wild carnivores. An evaluation of how a carnivore species is studied and its coexistence with sympatric and invasive species across diverse protected areas management regimes is crucial to develop robust landscape-scale conservation strategies.
... The human-carnivore battle is a common issue, and this is due to leopards' proteinrich diet (Treves and Karanth, 2003). Species undergo a high risk since in many landscapes of the NCL, no matter whether livestock off-take due to leopards is low, they may become victims even when there was attack by other carnivores, specifically if poisoning is used as leopards will scavenge their prey (Myers, 1976;Islam et al., 2014). Some herders knew the NCL's habit of coming back to eat unfinished prey in Heshun County, and a few leopards have died of poisoning in this area (Mobgabay . ...

China has four sub-species of leopard throughout the country. One of them is the North China leopard (Panthera pardus japonensis, Gray, 1862) which experiences a wide range of threats. It remains at the centre of interest for recent research and new management policies within its natural habitat. Due to limited studies for a long time, its current distribution, and population size remain vague without accurate information. Using existing literature, we synthesized information on this endemic and endangered subspecies. We used research engines such as Google scholar, Baidu and China National Knowledge Internet (CNKI) to find any available literature about the sub-species. By reviewing 39 published documents, nine national and international web news, and asking questions to some specialists in leopard and wildlife managers; we have concluded that the species' current distribution has drastically changed, only 2 % of its historical distribution remains occupied by around 174-348 individuals. Extant patches are in continual danger as the Proximity Index previously found was small. Habitat fragmentation, retaliation, and decline in prey species are the main threats. However, there is hope for its survival, since the mega project launched in 2015 "Bring Leopards Home" and new management policies are being undertaken in protected areas that will annihilate or reduce threats. In addition, many researchers or governmental organisations are currently carrying out studies on this sub-species. These studies will fill information gaps on the North China leopard based on scientific evidence.

The Arabian leopard Panthera pardus nimr is categorized as Critically Endangered, with < 200 individuals estimated to remain in the wild. Historically the species ranged over an extensive area of western Saudi Arabia but, with no confirmed sightings since 2014, investigating potential continued presence and distribution is of critical conservation importance. We present the results of a comprehensive survey designed to detect any remaining Arabian leopard populations in Saudi Arabia. We conducted 14 surveys, deploying 586 camera-trap stations at 13 sites, totalling 82,075 trap-nights. Questionnaire surveys were conducted with 843 members of local communities across the Arabian leopard's historical range to assess the presence of leopards, other predators and prey species. Predator scats were collected ad hoc by field teams and we used mitochondrial DNA analysis to identify the originating species. We obtained 62,948 independent photographs of animals and people, but none were of Arabian leopards. Other carnivores appeared widespread and domestic animals were numerous, but wild prey were comparatively scarce. Three questionnaire respondents reported sightings of leopards within the previous year, but targeted camera-trap surveys in these areas did not yield evidence of leopards. Of the 143 scats sent for analysis, no DNA was conclusively identified as that of the leopard. From this extensive study, we conclude there are probably no surviving, sustainable populations of Arabian leopards in Saudi Arabia. Individual leopards might be present but were not confirmed. Any future Arabian leopard conservation in Saudi Arabia will probably require reintroduction of captive-bred leopards.

NWRC has started a captive-breeding programme to secure the Arabian leopard and provide animals for future restocking or reintroduction. The establishment of a captive breeding programme is an important step in preventing the extinction of the Arabian leopard, even though not all leopards held in captivity on the Arabian Peninsula have yet been integrated into the breeding programme. In the meantime, most remnant populations will probably continue to decline. We do not know how much time we have left to save the Arabian leopard from extinction in the wild.
