Leopard density and interspecific spatiotemporal interactions in a hyena-dominated landscape.

Scavenging is widespread in the carnivore guild and can greatly impact food web structures and population dynamics by either facilitation or suppression of sympatric carnivores. Due to habitat loss and fragmentation, carnivores are increasingly forced into close sympatry, possibly resulting in more interactions such as kleptoparasitism and competition. In this paper, we investigate the potential for these interactions when carnivore densities are high. A camera trap survey was conducted in central Tuli, Botswana, to examine leopard Panthera pardus densities and spatiotemporal activity patterns of leopard and its most important competitors' brown hyena Parahyaena brunnea and spotted hyena Crocuta crocuta. Spatial capture–recapture models estimated leopard population density to be 12.7 ± 3.2 leopard/100 km2, which is one of the highest leopard densities in Africa. Time‐to‐event analyses showed both brown hyena and spotted hyena were observed more frequently before and after a leopard observation than expected by chance. The high spatiotemporal overlap of both hyena species with leopard is possibly explained by leopard providing scavenging opportunities for brown hyena and spotted hyena. Our results suggest that central Tuli is a high‐density leopard area, despite possible intense kleptoparasitism and competition.

Leopard (Panthera pardus) Food Habits in Shared Landscapes: A Case Study of Two Watersheds

Leopard ( Panthera pardus ) food habits was investigated in the human-used landscape of Dabka and Khulgarh Watershed areas of Kumoan Himalayan, Uttarakhan, India between September 2007 and June 2009. In total, 91 and 118 leopard scats were collected from Dabka and Khulgarh respectively. Prey items were identified using non-digested material isolated from scats, as well as a reference collection of hairs and bones from potential prey. Faecal analysis revealed that leopards preyed on 11 and 12 species in Dabka and Khulgarh, respectively. Total diet diversity of leopard was 2.98 in Dabka and 3.00 in Khulgarh. Sambar (53.41%) in Dabka and domestic dog (36.23%) in Khulgarh constituted the bulk of leopards diet both in terms relative prey biomass consumed. Comparison of the observed and expected frequency of occurrence of prey species in leopard diet rejected the hypothesis of non-selective predation in both the study sites. This study showed the survival strategies of leopard by switching diet according to the prey composition of the study area indicating that leopard can survive anywhere. The study highlights the wide dietary width of leopards identified in other research but rarely investigated in shared spaces. Such studies are crucial to the successfull management of "potentially harmful" wildlife in human-use areas. In particular, our result suggest that there is no single key for the existence of the leopard, which should rather depend upon on ecological features of the study area for example, abundance, prey composition, habitat condition and human settlement.

Food habit of Tiger (Panthera tigris) in Tropical Moist Deciduous Forest of Dudhwa National Park, Uttar Pradesh, India

Tiger ( Panthera tigris ) is an endangered felid on the IUCN list. Habitat loss, landscape fragmentation, prey depletion, and poaching have contributed to the decline of the tiger in its entire range in Asia. In India also, it survives only in well-protected tiger reserves and gone or decreased drastically in less-protected areas. The same situation is seen in the terai arc landscape. Thus, accurate knowledge of a species' diet is essential for effective conservation and is vital for conservation initiatives like habitat prioritization, protection, and restoration. Scats analysis was used to determine the food habit of tigers in the tropical moist-evergreen forest of Dudhwa National Park, northern India. A total of 116 scats were collected and analyzed. Scat contents were analyzed in terms of the relative frequency of occurrence and the relative prey biomass consumed. A minimum of 14 prey species were identified. In terms of frequency of occurrence and biomass, the most important prey species were barasingha ( Rucervus duvaucelii) and spotted deer ( Axis axis ), making up to 55% of biomass consumed. Domestic livestock contributed almost 10% to the diet of the tiger. The study revealed that tiger and leopard ( Panthera pardus ), the two main predators in Dudhwa Tiger Reserve, differentiate their niches by segregating the available resources as 55% of the tiger diet comprises barasingha and spotted deer. On the other side, leopard mainly feeds on spotted deer and rodents and may avoid direct competition from the tiger by shifting the space and diet, as revealed by another study in the same area.

Human-Leopard Panthera pardus (Linnaeus, 1758) Conflict in Godawari Municipality, Lalitpur, Nepal

Leopard (Panthera pardus) is a globally vulnerable large cat, widely distributed in Nepal. It occurs in different protected and outside protected areas in the human-dominated landscape. We used semi-structured questionnaires to know the Human-Leopard Conflict (HLC) and people’s perception towards Leopard conservation in the conflict-prone areas of Godawari, Lalitpur. The signs survey was conducted to know the presence of Leopards in the study area. Households were sampled using the snowball sampling technique. The presence of signs such as scats, pugmarks, and scents marks in the forest and nearby settlement areas indicated that there was a frequent occurrence of leopards in the study area. The Leopard frequently attacked livestock and pets and sometimes humans. Local people believed that the major reasons behind HLC were insufficient prey species and human disturbances in the habitat of Leopards. The majority of the respondents were against the conservation of Leopards because of the frequent depredation of domestic animals in the study area. The research findings will be useful in making a conservation action plan for Leopards and conflict mitigation strategies in such human-dominated semi-urban and urban landscapes.

Fecal glucocorticoid metabolite levels in captive Indian leopards (Panthera pardus fusca) housed under three different enrichment regimes.

Environmental enrichment improves the health and wellbeing of zoo animals. To test this hypothesis, we used Indian leopards (Panthera pardus fusca), one of the popular zoo animals, as a model organism to understand effects of active and passive enrichment elements on stress hormone levels of captive individuals. We included three enrichment categories, category 'A' (having both active: cage size of 1204 m3 with raised platforms and earthen flooring, and passive: controlled temperature, playback of forest sounds and sound proof glass to filter visitors' noise, enrichment elements), category 'B' (active enrichment type I, cage size of 264 m3 with air coolers), and category C (active enrichment type II, cage size of 517 m3 without air coolers) for leopards (n = 14) housed in two Indian zoos. We used a group-specific enzyme immunoassay to measure fecal glucocorticoid metabolites (fGCM) in captive leopards. For comparison, we analysed samples from free-ranging leopards, as well. fGCM levels (Mean±SEM) were 10.45±2.01 and 0.95±0.003 μg/g dry feces in captive and free-ranging leopards, respectively. Our results revealed that fGCM levels of leopards in categories B and C were significantly (P<0.05) different from each other, thus, indicating cage size (an active enrichment element) as an important factor in influencing the physiology of the sampled animals. Overall, the findings of the study will contribute towards informed policies for management of captive Indian leopards.

Habitat thresholds for successful predation under landscape change

ContextHabitat loss and alteration affect wildlife populations worldwide. Bush encroachment alters landscapes and threatens arid and semi-arid grasslands, but its effects on predator–prey relationships and carnivore community ecology are not well understood. Predation strategies of large predators, for example high-speed pursuits versus ambush from short distances, are likely to be affected differently by bush encroachment.ObjectivesWe assessed how bush encroachment affects overall predation success of cheetahs (Acinonyx jubatus) and leopards (Panthera pardus) in a savanna landscape under variable fractional woody cover (FWC). We tested if predation success remained relatively unchanged for leopards across a gradient of FWC, and whether cheetah predation was most successful at low to intermediate cover and varied seasonally.MethodsBelly scores of predators were measured from camera-trap images collected over 7 years in north-central Namibia and used to index predation success. We derived predicted belly score probabilities as a function of FWC, which was measured using a Synthetic Aperture Radar (SAR)-derived satellite data layer.ResultsPredicted leopard predation success was highest at 0.27–0.34 FWC in the dry season, potentially due to lower prey density in highly covered areas and decreased prey catchability in low cover. Predicted cheetah predation success was highest at 0.24–0.28 FWC in the wet season, potentially due to increased landscape openness, high availability of habitat margins for visualising and stalking prey, and decreased kleptoparasitism by leopards. These results highlight optimal habitat cover thresholds that favour lower FWC for cheetah than for leopard.ConclusionsThe findings indicate that landscape heterogeneity is important for predation success of cheetahs and leopards, suggesting that habitat management should focus on bush control efforts to maintain intermediate levels of bush cover.

The hunter and the hunted: Using web‐sourced imagery to monitor leopard (Panthera pardus pardus) trophy hunting

AbstractSustainable offtake of any threatened species and objective monitoring thereof relies on data‐driven and well‐managed harvest quotas and permit compliance. We used web‐sourced images of African leopard (Panthera pardus pardus) trophy hunts to determine whether online photographs could assist in monitoring and documenting trophy hunting in Africa. Of 10,000 images examined, 808 (8%) showed leopard trophy hunts and could be contextualized by date and country. From a subset of photos (n = 530), across six countries between 2011 and 2020, we extracted information on the leopards killed and hunter demographics. We found no significant differences in leopard sex, age, or shot wound position between countries, and most trophy leopards were in good physical condition. Most hunters were White (96%) and estimated at over 40 years old (82%), with the proportion of women hunters in younger age classes significantly higher than in older classes. Rifles, bows, and hounds were used in all countries, except Tanzania and Zambia, where rifles were exclusively used. Online images could not be reasonably compared to the CITES trade database, but in South Africa, more than half (57%) of all nationally registered leopard trophy hunts in the last decade (2010–2020) have been posted online. Online images also reveal hunting violations, including non‐permitted hunting of female leopards and illegal hounding. Such monitoring methods may become increasingly useful as social media usage grows and provide valuable insight into this multi‐million dollar industry.

Evidence for a critical leopard conservation stronghold from a large protected landscape on the island of Sri Lanka

The decline and extirpation of large carnivore populations can lead to cascading effects in natural ecosystems. An understanding of large carnivore population densities, distribution and dynamics is therefore critical for developing effective conservation strategies across landscapes. This is particularly important in island environments where species face increased extinction risk due to genetic isolation coupled with local losses of finite habitat. The Sri Lankan leopard Panthera pardus kotiya is one of two remaining island-living leopards on Earth and the only apex predator in Sri Lanka. Despite its iconic status in Sri Lanka, robust research on the species has been limited to only a handful of scientific studies, limiting meaningful scientific recommendations for the species’ conservation and management. In this study, we conducted a single season camera trap survey in Sri Lanka’s largest protected area, Wilpattu National Park (1317 km 2 ), located in the country’s northwest. Our objective was to estimate key ecological state variables of interest (density, abundance, sex-specific movement and spatial distribution) of this leopard subspecies. Our results indicate that Wilpattu National Park supports a density of 18 individuals/100 km 2 (posterior SD=1.5; 95% HPD interval=16–21) with a mean abundance of 144 (posterior SD=15) individual leopards and a healthy sex ratio (f:m=2.03:1). The estimated activity range for male leopards > 2 years old was 49.53 km 2 (Posterior SD=3.43; HPD interval=43.09–56.41) and for female leopards > 2 years old was 22.04 km 2 (Posterior SD=1.82; HPD interval=18.34–25.65). This density falls at the higher end of published estimates for the species anywhere in its global range, based on similar methods. Given Sri Lanka’s limited size, this national park system should be considered as a critical stronghold that maintains a source population of leopards, contributing to the long-term population viability of leopards in the larger landscape.

Maximum Entropy Niche-Based Predicting of Potential Habitat for the Anatolian Leopard (Panthera pardus tulliana Valenciennes, 1856) in Türkiye

The Anatolian leopard (Panthera pardus tulliana Valenciennes, 1856) is the largest surviving cat species in Türkiye. Despite the adversity they face, leopards still exist in Türkiye. In this study, using the maximum entropy model (MaxEnt), potentially suitable habitats for the Anatolian leopard in Türkiye was surveyed. When evaluating leopard habitat preference, the fact that the species can easily adapt to its habitat and live anywhere with sufficient vegetation and sufficient prey animals was taken into account; only data on climate which affects the geographic distribution patterns and population structures of flora and fauna were examined before. When the climatic variables affecting leopard’ distribution were examined, the following had the highest values: isothermally, seasonal temperature, average temperature of the coldest season, minimum temperature of the coldest month, and annual precipitation. Except for the Central Anatolia Region and coastal areas, almost every region in Türkiye contains habitats suitable for the leopard. There are scarce data on leopards’ populations and habitats in Türkiye. Therefore, even though ecological niche modelling (ENM) may generate important results when determining potentially suitable habitats, it is clear that this model cannot yield accurate results without considering the areas that the species is known to inhabit but in which no studies were previously conducted. The results that were obtained in the present study can also provide background information related to the long-term conservation of this species.

First record of organochlorine pesticides in blood of wild and captive African leopards, Panthera pardus pardus (Linnaeus, 1758)

Compared to aquatic ecosystems, limited information exists on organochlorine accumulation in terrestrial ecosystems, and this is specifically true for terrestrial carnivores that have received limited attention in terms of studies on pollutant bioaccumulation. The African Leopard, Panthera pardus pardus (Linnaeus, 1758), is a popular focal species for research by ethologists and ecologists, but a noticeable knowledge gap exists with regards to toxicological aspects. To address this gap, the aim of this study was to determine baseline organochlorine pesticide (OCP) concentrations in blood of live wild and captive leopards in South Africa, and to explore the relationship between OCP levels and different conservation management strategies. Peripheral blood samples of seven captive and seven wild leopards, representing regular and melanistic individuals within the captive population, were collected while under sedation. The ΣOCP concentrations in blood serum were detected by means of GC-ECD. Statistical relationships among pesticide content in leopards from three geographical areas, different sexes, age groups and conservation status were examined. Captive leopards from this study had a slightly higher mean ΣOCP concentration (901 pg/ml) than wild leopards (768 pg/ml), and captive females had lower mean levels of ΣOCPs (797 pg/ml) than males (1,058 pg/ml). OCPs accumulated in the following order DDTs (27%) &amp;gt; HCHs (21%) &amp;gt; Heptachlors (15%) &amp;gt; CHLs (15%) &amp;gt; Drins (14%) &amp;gt; HCB (8%). Differences in OCP composition profiles of resampled captive individuals were also found. The sources of OCPs in the leopards can be attributed to the historic and current use of, e.g., DDT and HCHs, for malaria vector control and in insecticides/avicides in South Africa. For the captive leopards in this study the main source is possibly contaminated chicken that formed the major portion of their diet. This is the first report on OCP concentrations from leopards in Africa and highlights the need for this parameter to be considered in terms of the conservation management of healthy populations.

Patterns of predation and meat-eating by chacma baboons in an Afromontane environment

Abstract Meat-eating among non-human primates has been well documented but its prevalence among Afromontane baboons is understudied. In this study we report the predatory and meat-eating behaviours of a habituated group of gray-footed chacma baboons (Papio ursinus griseipes) living in an Afromontane environment in South Africa. We calculated a vertebrate-eating rate of 1 every 78.5 hours, increasing to 58.1 hours when unsuccessful predation attempts were included. A key food source was young antelopes, particularly bushbuck (Tragelaphus scriptus), which were consumed once every 115 observation hours. Similar to other baboon research sites, predations seemed mostly opportunistic, adult males regularly scrounged and monopolised prey, there was no evidence they used an active kill bite, and active sharing was absent. This is the first baboon study to report predation of rock python (Python sebae) eggs and likely scavenging of a leopard (Panthera pardus) kill (bushbuck) cached in a tree. We also describe several scramble kleptoparasitism events, tolerating active defence from antelope parents, and the baboons inhibiting public information about predations. In the latter case, baboons with meat often hid beyond the periphery of the group, reducing the likelihood of scrounging by competitors. This often led to prey carcasses being discarded without being fully exploited and potentially providing resources to scavengers. We also highlight the absence of encounters with numerous species, suggesting the baboons are a key component of several species’ landscapes of fear. Given these findings it seems likely that their ecological role in the Soutpansberg has been undervalued, and such conclusions may also hold for other baboon populations.

Chromosome-level Genome Assembly of the High-altitude Leopard (Panthera pardus) Sheds Light on Its Environmental Adaptation.

The leopard (Panthera pardus) has the largest natural distribution from low- to high-altitude areas of any wild felid species, but recent studies have revealed that leopards have disappeared from large areas, probably owing to poaching, a decline of prey species, and habitat degradation. Here, we reported the chromosome-scale genome assembly of the high-altitude leopard (HL) based on nanopore sequencing and high-throughput chromatin conformation capture (Hi-C) technology. Panthera genomes revealed similar repeat composition, and there was an appreciably conserved synteny between HL and the other two Panthera genomes. Divergence time analysis based on the whole genomes revealed that the HL and the low-altitude leopard differentiate from a common ancestor ∼2.2 Ma. Through comparative genomics analyses, we found molecular genetic signatures that may reflect high-altitude adaptation of the HL. Three HL-specific missense mutations were detected in two positively selected genes, that is, ITGA7 (Ala112Gly, Asp113Val, and Gln115Pro) and NOTCH2 (Ala2398Ser), which are likely to be associated with hypoxia adaptation. The chromosome-level genome of the HL provides valuable resources for the investigation of high-altitude adaptation and protection management of the vulnerable leopard.

Detection of SARS-CoV-2 in a free ranging leopard (Panthera pardus fusca) in India.

We report an incidence of natural infection of SARS-CoV-2 in free-ranging Indian leopard (Panthera pardus fusca). The case was detected during routine screening. Post-mortem and laboratory examination suggested virus-induced interstitial pneumonia. Viral genome could be detected in various organs including brain, lung, spleen, and lymph nodes by real-time PCR. Whole-genome sequence analysis confirmed infection of Pango lineage B.1.617.2 of SARS-CoV-2. Till now, only Asiatic lions have been reported to be infected by SARS-CoV-2 in India. Infections in animals were detected during peak phase of pandemic and all the cases were captive with close contacts with humans, whereas the present case was observed when human cases were significantly low. No tangible evidence linked to widespread infection in the wild population and the incidence seems to be isolated case. High nucleotide sequence homology with prevailing viruses in humans suggested spillover infection to the animal. This report underlines the need for intensive screening of wild animals for keeping track of the virus evolution and development of carrier status of SARS-CoV-2 among wildlife species.

A pattern of livestock depredation by snow leopard to the yak herding pastoralist in western Bhutan

The pastoralists co-exist with wild predators and livestock depredation by predators causes an immense impact on the livelihood of the herders and instigates a negative attitude towards the conservation of these wild predators. Yak herders in western Bhutan move from place to place for herding on pasture and they face challenges with livestock predation by top predators like snow leopard (Panthera uncia) and dhole (Cuon aplinus). To investigate patterns of livestock depredation by the snow leopard and determine the attitude of herders towards snow leopard conservation, we conducted a household interview with all 56 itinerant yak herders in the west of Bhutan. Each herd was keeping a mean of 84 (± 29) yaks per herd. Yaks were mainly kept for milk and bulls for breeding and bullocks for meat to sustain their family livelihood. Predation of livestock by predators (42.9%) was among the top problems faced by the yak herders. A total of 398 yaks were lost to snow leopards (78.86%) followed by dhole (18.3%), Himalayan black bear (Ursus thibetanus) (2.7%), and common leopard (Panthera pardus) (0.2%) in the past 5 years (2015–2019). The majority (87.22.8%) of the kills by snow leopards were young yak and most (60.5%) kills were recorded during summer. Snow leopards are considered harmful (73.2%), and herders (71.1%) are not in favour of snow leopard conservation. Herders’ conflict with snow leopards is severe in the current study site, and we recommend social development for conservation programmes like livelihood alternatives for the herders, compensation and insurance schemes, and conservation awareness programmes for the yak herders as an intervention to create harmonic co-existence between the yak herder and the snow leopard.

Importance of non-journal literature in providing evidence for predator conservation

The literature other than scientific journals (non-journals) is a valuable, but scattered and rarely used, source of evidence of the effectiveness of interventions applied for protection from mammalian predators. This study describes how journals and non-journals differ in relation to study designs, types of interventions, predator species, countries, and publication bias. I collected 411 journal cases (226 publications) and 97 non-journal cases (64 publications) covering the period 1955–2020, five study designs, six interventions, 28 species and 50 countries. Non-journals were important for two predators (leopard Panthera pardus and snow leopard P. uncia) and four countries (Canada, India, Russia and Sri Lanka). These species and countries have been affected by human-predator conflicts and the use of non-journals should become a habitual practice to mitigate conflicts. Information on other species and countries, and all study designs and interventions, was provided mostly or only in peer-reviewed journals. This study helps make the use of non-journals easier for researchers and conservation practitioners by providing and explaining a list of relevant literature and online resources.

Habitat use of and threats to African large carnivores in a mixed-uselandscape.

Large carnivores increasingly inhabit human-affected landscapes, which exhibit heterogeneity in biotic resources, anthropogenic pressures, and management strategies. Understanding large carnivore habitat use in these systems is critical for their conservation, as is the evaluation of competing management approaches and the impacts of significant land-use changes. We used occupancy modeling to investigate habitat use of an intact eastern African large carnivore guild across the 45,000 km2 Ruaha-Rungwa landscape in south-central Tanzania. We determined the relative impact on five large carnivore species of biotic, anthropogenic, and management factors at the scales of home range selection and short-term use within home ranges. We also specifically tested the effect of abandonment of trophy hunting areas on large carnivore occurrence. Patterns of habitat use differed among species. Lions (Panthera leo) appeared affected by top-down limitation, as their occurrence was significantly negatively associated with illegal human activity (β = -0.63 [SE 0.28]). African wild dogs (Lycaon pictus), instead, were limited by biotic features; the species was negatively associated with riverine areas of high sympatric predator density (β = -1.00 [SE 0.43]) and used less-productive habitats. Spotted hyaena (Crocuta crocuta) and leopard (Panthera pardus) persisted in more disturbed areas and across habitat types. Large carnivore occurrence was not affected by whether an area was used for photographic or trophy hunting tourism; regular law enforcement was instead a better predictor of occurrence. All species fared better in actively managed hunting areas than those that had been abandoned by operators. Overall, our findings highlight the divergent habitat requirements within large carnivore guilds and the importance of adopting an integrated approach to large carnivore conservation planning in modern systems. We also identified a novel threat to African conservation areas in the form of decreased management investments associated with the abandonment of trophy hunting areas.

Generalization of threats attributed to large carnivores in areas of high human-wildlife conflict.

Fear-induced generalization of threats to noninimical stimuli is a behavioral tendency of humans to minimize exposure to potential threats. In human-carnivore conflict zones, people often generalize their fear of predation by obligate carnivores to nonobligate carnivores despite differences in species' predation rates. We investigated the effect of a perceived threat of large obligate carnivores to livestock on tolerance and perception of striped hyena (Hyaena hyaena) in an area of high human-carnivore conflict. We surveyed 197 households through asemistructured questionnaire to determine people's perception and tolerance of striped hyenas in Sathyamangalam and Mudumalai Tiger Reserves after identification of the current distribution range of hyena determined through camera trap and sign surveys. Through the random forest algorithm, we modeled the level of tolerance of striped hyena as a function of loss of livestock to predation and from disease, the perceived threat of predation by hyena, and other socioeconomic attributes. Animal husbandry was a major source of income but was severely affected by livestock loss due to predation and disease. Sixty-nine percent of people were uncertain about predatory behavior of hyena; out of that, 23% reported a negative conservation attitude. Only 6 instances of hyena depredation on livestock and 2 on dogs were reported. Our model confirmed that economic instability associated with increased loss to predation and disease, livestock dependency, and a decrease in family annual income negatively affected people's tolerance of hyena. Perceptual uncertainty related to predatory behavior of hyena also negatively affected people's tolerance. In our study area, economic instability and perceptual uncertainty led to generalization of fear of large carnivores to a nonobligate predator. Such generalization may affect the attitude of people toward many other species. Understanding the role of economic instability and perceptual uncertainty should facilitate conservation of species, such as the hyena, that are vulnerable to false generalization.

Diversity, distribution and conservation of land mammals in Mauritania, North-West Africa

Detailed knowledge about biodiversity distribution is critical for monitoring the biological effects of global change processes. Biodiversity knowledge gaps hamper the monitoring of conservation trends and they are especially evident in the desert biome. Mauritania constitutes a remarkable example on how remoteness and regional insecurity affect current knowledge gaps. Mammals remain one of the least studied groups in this country, without a concerted species checklist, the mapping of regions concentrating mammal diversity, or a national assessment of their conservation status. This work assessed the diversity, distribution, and conservation of land mammals in Mauritania. A total of 6,718 published and original observations were assembled in a spatial database and used to update the occurrence status, distribution area, and conservation status. The updated taxonomic list comprises 107 species, including 93 extant, 12 Regionally Extinct, and 2 Extinct in the Wild. Mapping of species distributions allowed locating concentrations of extant mammal species richness in coastal areas, along the Senegal River valley, and in mountain plateaus. Recent regional extinction of large-sized Artiodactyla and Carnivora has been very high (11% extinct species). From the extant mammals, 11% are threatened, including flagship species (e.g., Addax nasomaculatus and Panthera pardus). Species richness is poorly represented by the current protected areas. Despite the strong advances made, 23% of species categorise as Data Deficient. Persisting systematics and distribution uncertainties require further research. Field surveys in currently unexplored areas (northern and south-eastern regions) are urgently needed to increase knowledge about threatened mammals. The long-term conservation of land mammals in Mauritania is embedded in a complex web of socioeconomic and environmental factors that call for collaborative action and investment in sustainable human development. The current work sets the baseline for the future development of detailed research studies and to address the general challenges faced by mammals and biodiversity in the country.
