Multiscale spatially explicit modelling of livestock depredation by reintroduced tiger (Panthera tigris) to predict conflict risk probability

Understanding the causal factors associated with human/livestock-large carnivore conflict and distribution of conflict risk is key to designing effective preventative and mitigation strategies. Spatial modelling of human-carnivore conflict has recently gained traction, and predictive maps have become a great tool to understand the distribution of present and future conflict risk. However, very few such studies consider scale and use appropriate spatial modelling tools. We aimed to understand the ecological correlates of human-tiger (Panthera tigris) conflict, predict livestock predation risk by reintroduced tigers in Panna Tiger Reserve, Central India and understand the prey-predator dynamics behind the conflict. We modelled livestock kill as a function of various tiger relevant ecological variables at multiple scales employing spatially explicit statistical tools. As a first step, we used geostatistical modelling to create raster layers of covariates (prey, cover, human activities), following which we did univariate scaling. We then modelled livestock loss by tiger using a geoadditive model. Employing this model, we predicted and mapped conflict risk probabilities within our study site. It was found that prey and shrub cover both selected at a fine scale, were key ecological determinants of human-tiger conflict. Prey showed an inverse relationship while shrub showed non-linear relationship with livestock predation. Which lead us to conclude that in habitats where optimum ambush cover is available but prey presence is low at fine-scale, carnivores are more likely to depredate domestic livestock since livestock have lost most of their anti-predator behaviours. Livestock kill by tiger is thus a culmination of predator choice and foraging tactics, and prey vulnerability and defence mechanism. The spatially explicit predation risk map produced in this study can guide adequate human-tiger conflict prevention measures.

Knowledge of Wildlife, Hunting, and Human-felid Interactions in Maya Forest Communities of the Northern Yucatán Peninsula, Mexico

Human-wildlife impacts threaten large-felid persistence in the northern Yucatán Peninsula, triggered largely by livestock depredation. We aimed to explore knowledge and attitudes about local wildlife in relation to husbandry practices, hunting habits, and human-wildlife interactions, in three Maya Forest communities. A questionnaire survey of 30 long-established smallholdings, where livelihood depended on a private fenced plot and surrounding communal forest, found wide knowledge of local wildlife, perception biases for abundances of game species, and preference for living amongst wild herbivores over carnivores. Interviewees had concerns about perceived year-on-year decreases in local wildlife, attributed to regular subsistence hunting by their communities. The few interviewees reporting large-felid attacks on their livestock subsequently altered management practices to prevent further attacks. The region suffers from a poverty trap of subsistence hunting by smallholders needing protein supplement potentially exacerbating depredation on the livestock that sustain their economies by large felids deprived of their natural prey.

Negative interactions between humans and Asiatic black bears (Ursus thibetanus) in northern Pakistan

AbstractThe conservation of the vulnerable Asiatic black bear (Ursus thibetanus) in Pakistan is challenged by retaliatory killing, driven by negative interactions between people and bears, such as livestock depredation. We distributed a questionnaire among 369 individuals in rural communities within the Mansehra District, Pakistan, where bear retaliatory killings are often reported. We focused on human–Asiatic black bear negative interactions, such as livestock depredations, crop damage, and human injuries occurring between 2015 and 2019. Although the number of livestock depredation events was small in absolute terms (an average of 11.5 livestock heads reported to be killed annually), it had a large estimated economic impact in terms of local economies ($1367 per year, or a total of $5.469 between 2015 and 2019). Such annual estimated costs account for 93% of the per capita gross domestic product for Pakistan, roughly equivalent to $55,853 for a US citizen. Additionally, 30 incidents between people and bears were registered, where 6% human were fatal. We recommend awareness campaigns on different mitigating interventions, and training on how to use them, as well as behaviors to reduce the risk of negative interactions.

Awareness of urban communities on biodiversity conservation in Tanzania’s protected areas

This study used semi-structured interviews in two cities, Dodoma and Arusha, in Tanzania, to assess the difference in people’s conservation awareness between the two cities. Our results revealed that urban people were generally positive towards most statements related to biodiversity conservation in protected areas, and in a few cases, variations between people from different occupations and education levels were significant. For instance, 87% (n = 376) of our respondents agreed with the statement "The knowledge obtained through conservation education is very important in changing our attitude towards protected areas," as well as 71% (n = 376) of our respondents agreed with the statement that "It is important to involve school children in conservation education." We predicted that people in Arusha would be more positive toward all six conservation statements than people in Dodoma (the capital city) because Arusha is close to many protected areas and is a tourist hub. We also predicted that people in Arusha would have more knowledge and awareness of biodiversity conservation than those in Dodoma. However, this prediction was not supported as people from Dodoma were significantly more positive than people from Arusha. This indicates that people in Dodoma are more concerned about biodiversity conservation than people in Arusha. This variation might be influenced by the costs associated with conservation, as people in urban Dodoma live far from conservation challenges such as livestock depredation and/or crop raiding compared to people in urban Arusha.

Anthropogenic mortality of large mammals and trends of conflict over two decades in Nepal.

Wildlife conservation in human‐dominated landscapes faces increased challenges due to rising conflicts between humans and wildlife. We investigated the human and wildlife loss rates due to human–wildlife conflict between 2000 and 2020 in Nepal. We concentrated on Asian elephant (Elephas maximus), greater one‐horned rhino (Rhinoceros unicornis), tiger (Panthera tigirs), and leopard (Panthera pardus) mortality, as well as human mortality caused by these species. Over the 21‐year period, we recorded 1139 cases of wildlife mortality and 887 cases of human mortality. Leopard mortality was the highest, followed by that of greater one‐horned rhinos, tigers, and Asian elephants. Overall, the rate of wildlife mortality has been increasing over the years. Asian elephants were found to be more responsible for crop damage than greater one‐horned rhinos, while leopards were found to be more responsible for livestock depredation than tigers. The generalized linear model indicated that the mortality of wildlife in the districts is best predicted by the additive effect of human mortality, the proportion of agricultural land, and the literacy rate of the districts. Retaliatory wildlife mortality was the most challenging issue for wildlife conservation, especially for the large mammals. Findings from this study are important for mitigation of human–wildlife conflicts, controlling retaliatory killing, and conserving these threatened large mammals.

Ecology of Indian wolf Canis lupus pallipes in the Great Indian Bustard Sanctuary, Nannaj, Solapur, Maharashtra, India

The Indian wolf, Canis lupus pallipes is an endangered carnivore of India listed in Schedule-1 of the Indian Wildlife (Protection) Act, 1972. There is not much information available on the species and with this perspective, the present study was initiated in the Great Indian Bustard Sanctuary in Maharashtra. Direct and indirect evidences were used to assess its population status and distribution, habitat use, feeding ecology, denning behaviour and wolf-human conflict emanating due to livestock depredation. Intensive ecological and behavioural studies were conducted at Nannaj on one pack between 1991 and 1994. The wolf survives all over the Sanctuary, which is densely populated by humans as elsewhere in its distribution range in India where wolf-human conflicts are common arising either due to livestock depredation or child-lifting. Usually, large packs were present in Blackbuck Antilope cervicapra areas whereas smaller packs inhabited areas not supporting healthy populations of Blackbuck. In Blackbuck poor areas, the wolf survived mainly on livestock. The Sanctuary supports 40-58 wolves. The wolves had a seasonal pattern of habitat use related to movement of prey and livestock. Wolves selected those areas as rendezvous sites which had higher prey density, vegetation cover, minimum human disturbance and were located close to water source. On an average wolves consumed 3.68 (S.E.=0.17) kg/wolf/kill and kill periodicity was 3.65 days (S.E.=0.58). Wolves preyed largely on blackbuck during the non-breeding period and livestock during denning period. Predation was higher on male blackbuck than females despite female biased sex ratio. The average litter size of three packs was recorded to be 5 (range 4-6). The dominant male and female wolves guarded the dens more often than the helpers. They used multiple dens for raising pups that were excavated and/or renewed during denning period. Important conservation problems of wolf have also been discussed in the paper.

Pastoral practices, pressures, and human-wildlife relations in high altitude rangelands of eastern Himalaya: A case study of the Dokpa pastoralists of North Sikkim

The pastoral practices of the Dokpa herders of North Sikkim have been transforming in response to the geo-political and socio-economic changes in the region. Against the backdrop of these changes, this study aims to understand the current state of pastoralism in North Sikkim with three specific objectives: (i) to understand the current rangeland management practices of the Dokpa community; (ii) to examine the social, political and ecological stresses to continuity of traditional pastoral livelihoods; and (iii) to document the baseline on human-wildlife relations. We focused on one of the two subset populations of Dokpa herders of North Sikkim and, using a mixed-methods approach, conducted 12 semi-structured interviews, four key respondent interviews and two focused group discussions. The resource use by the Dokpas is unique, and unlike the rest of the Himalayan range, they access the high-altitude pastures in winters and the lower ones in summer. Pastures in the higher altitudes experience heavier winds, which leads to lower levels of snow deposition — thus ensuring access to dried pasture forage for livestock during the lean season. The decisions pertaining to resource management are taken by the head of the local institution Dzumsa, the Pipon. Primary stresses to the continuation of traditional pastoral practices are fragmentation of pastureland post-Sino-Indian war of 1962 and the consequent establishment of armed forces, livestock depredation by free-ranging dogs followed by wild predators and continued socio-economic marginalisation of the pastoralists under a supposedly egalitarian institutional regime. Extreme climatic events in the recent past have also contributed to significant livestock loss. Dokpa transhumant practices are on an overall decline, with most members of the younger generation shifting to non-herding livelihoods. The availability of alternate livelihood options with the improved connectivity, access to education and development of the tourism industry has led to changing aspirations of the younger generations. In only two of the twelve households we surveyed, the younger generation continues herding, while the rest have moved to the cities and towns. In terms of human-wildlife relations, the respondents mostly hold a positive attitude towards wildlife and conservation actions despite livestock predation by wild predators, since the free-ranging dogs cause the highest livestock loss. With the inputs from the Dokpas, we provide recommendations towards a facilitative environment for the continuation of the traditional herding in the region, which is critical for the survival of pastoralism in North Sikkim, presently hinged on less than two dozen of elderly Dokpas.

Blue sheep strongly affect snow leopard relative abundance but not livestock depredation in the Annapurna Conservation Area, Nepal

Large carnivores play key roles in their ecosystems, but their protection is a major challenge in biodiversity conservation due to conflicts with human interests. The snow leopard ( Panthera uncia ) is the top predator of Asian high-altitude landscapes and faces various threats including wild prey depletion and illegal killings as a consequence of livestock depredation. As the interactions between snow leopards, wild prey, and livestock are still insufficiently understood, we studied the effects of 1) wild prey (blue sheep Pseudois nayaur and Himalayan marmots Marmota himalayana ) and domestic prey on snow leopard relative abundance, and of 2) these ecological parameters and intervention applications on livestock depredation by snow leopards. In the Annapurna Conservation Area, Nepal, we monitored wildlife populations and livestock along transects (490.8 km) in 82 grid cells (4 ×4 km) in 2019 and 2021 and conducted questionnaire surveys to determine livestock depredation between 2018 and 2021 (n = 479 households). We applied generalized linear models (GLMs) and sample comparison testing to examine the effects of prey densities and other environmental and anthropogenic predictors on snow leopard relative abundance and livestock depredation. Blue sheep density strongly positively affected snow leopard relative abundance, which also increased with terrain ruggedness and decreased with increasing densities of livestock and the human population. The size of livestock holdings shaped depredation events of large livestock (yak, cattle and horse), whereas depredation events of sheep and goats, which accounted for most (68.6%) depredated animals, decreased with increasing human population density and marmot presence. The strong impact of blue sheep on snow leopard relative abundance supports demands for integrating this ungulate into conservation and management plans, including wild prey recovery and translocation. The rather weak evidence for effects of blue sheep on depredation events suggests that conflicts over livestock depredation by snow leopards would neither be inflicted nor solved by increasing wild prey abundance. This demonstrates the need to improve intervention strategies in the Annapurna region, such as predator-proofing corrals and optimizing daytime herding practices. We suggest further exploring the effects of marmots and other secondary prey on livestock depredation rates, and testing the suitability of additional interventions, e.g., dogs and deterrents, as conflict mitigation tools. Our results will support wildlife managers in setting conservation priorities to promote the long-term co-existence of local people and snow leopards. • Blue sheep strongly shape snow leopard relative abundance in the Annapurna region. • Livestock losses in the Annapurna region are mainly associated with husbandry factors. • Wild prey restoration and improved husbandry practices should benefit snow leopards.

A Model for Iberian Wolf (Canis lupus signatus, Cabrera 1907) Predation Risk Assessment on Cattle in the Central System (Spain)

As a consequence of the exponential increase of the demographic and technological development of the human being, conflicts with the natural environment are accentuated. Pollution or the loss of biodiversity represent examples of problems that we must face to maintain the balance between the evolution of human beings and the conservation of nature. However, there are conflicts whose origin is not as modern as those mentioned, and we return to the Neolithic to find the origin of the conflict of man with the great predators. This condition has existed since then and at this point in history, is reaching very high levels of tension in developed countries, as a result of the depredation of livestock. Wolf is one of the species that generates more conflict and is currently suffering a slight demographic expansion. Although current laws mostly seek their recovery and conservation, the wolf is experiencing great difficulties due to the poor social perception it has. Faced with this situation, a model has been developed using geographic information systems which categorizes the areas according to their probability that the cattle could suffer a wolf attack. Based on natural and anthropogenic variables of the environment, the areas with a greater or lesser probability of attack were evaluated, with the objective of designing a prevention plan to reduce or eliminate the attacks. Since different authors demonstrate that population control measures on the species are not effective in reducing attacks on livestock, the solution to the conflict should be based on preventive measures. The use of the designed model will enable the competent authorities to apply these measures optimally, reducing expenses and allowing to anticipate future areas of conflict.

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.

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.

Spatial Determinants of Livestock Depredation and Human Attitude Toward Wolves in Kailadevi Wildlife Sanctuary, Rajasthan, India

Gray wolves are capable of adapting to human-dominated landscapes by utilizing domestic prey as a source of food. Livestock depredation by wolves incurs a heavy economic loss to the villagers, resulting in negative attitudes toward the species and leading to increased conservation conflict. We used multi-state occupancy modeling on the interview data to assess the ecological factors governing livestock depredation by wolves. We also assessed the socio-demographic factors that may govern the attitude of villagers toward the wolf using ordinal regression. Over the past year, 64% of respondents reported a loss of livestock, in which goats (63%) comprised the major share, followed by sheep (22%) and cattle calves (15%). Wolves tend to hunt medium-sized domestic prey (sheep and goats) that commonly graze in open agricultural areas. The estimated livestock depredation probability of wolves was 0.84 (SD = ± 0.23). Depredation probability was influenced by habitat use by wolves, the extent of agricultural areas, scrubland area, and settlement size. Respondents with prior experience of livestock loss held more negative attitudes. Shepherds held more negative attitudes than other occupations. Increases in the respondent’s age and education level reflected a positive shift in attitudes toward the wolf. High economic loss caused by livestock depredation by wolves can lead to retaliatory persecution of wolves. Adequate compensation for livestock loss, along with better education and awareness can help lead to coexistence between wolves and humans in multi-use landscape of Kailadevi Wildlife Sanctuary, Rajasthan, India.

Multispecies study of patterns and drivers of wildlife impacts on human livelihoods in communal conservancies

AbstractFarmers in developing countries often work in challenging environments with poor infrastructure, marginal agricultural potential, and limited economic opportunities. These challenges are exacerbated when wildlife impact human livelihoods. Here, we analyze data quantifying the type and frequency of human‐wildlife impacts within communal conservancies across Namibia and explore possible drivers of temporal and spatial variation of these data. A total of 112,165 human‐wildlife impacts were reported between 2001 and 2019 at the national level, with livestock depredation the most common. Marked regional variation was however evident with crop raiding and attacks on humans more prevalent in the mesic North‐East, and both livestock depredation and infrastructure damage highest in the arid north‐western regions. Elephant, jackal, hyena, cheetah, and leopard (in descending order) were the species most frequently linked to reported damage. Distance to the nearest protected area and river, terrain ruggedness, conservancy size, and annual rainfall (amongst others) all had a significant impact on both the distribution and extent of human‐wildlife impact reports. Reports did not vary significantly with years but were significantly influenced by average monthly rainfall. Understanding spatial and temporal patterns of human‐wildlife impacts at a national scale, in addition to their potential drivers, allows for the identification of conflict hotspots and the allocation of resources and expertise to mitigate them. Ultimately, mitigating negative interactions between people and wildlife will allow for the continued sharing of space and with that the sustainability of a model that has seen a dramatic increase in both the distribution and abundance of wildlife in Namibia.

Vulnerability of land use/cover associated with human-wildlife conflicts in Mullaitivu District, Sri Lanka

Human-wildlife conflict has increased over the decades and is now considered one of the most severe challenges to the survival of threatened species and the livelihood of communities worldwide. In Sri Lanka, population growth, fragmentation of land, and conversion of natural wildlife habitats into settlement and agricultural areas are the leading causes of human-wildlife conflict. This study seeks to characterise the conflict pattern in the Mullaitivu District by identifying land use/cover changes and assessing the vulnerability of land use/cover. Primary data were collected through a field survey using a structured questionnaire and direct observation methods, and secondary data on land use/cover changes were obtained from remote sensing images. These data were analysed statistically and on the Geographic Information System (GIS) platform. The study reveals land use/cover vulnerability status over the twenty-six years. Dense forests are on the decline, and wild animals migrate into human settlements and agricultural sites, resulting in different types of human-wildlife conflict such as crop damage, livestock depredation, and loss of life and/or injuries to both people and wildlife in the Mullaitivu district. People employ various wildlife mitigation strategies. However, they cannot safeguard their crops or livestock from these animals. By implementing appropriate management measures to avoid wildlife infiltration into human settlements, the human-wildlife conflict in the Mullaitivu district can be minimised.

Living with a large predator: Assessing the root causes of Human-brown bear conflict and their spatial patterns in Lahaul valley, Himachal Pradesh.

Brown bear‐mediated conflicts have caused immense economic loss to the local people living across the distribution range. In India, limited knowledge is available on the Himalayan brown bear (HBB), making human–brown bear conflict (HBC) mitigation more challenging. In this study, we studied HBC in the Lahaul valley using a semi‐structured questionnaire survey by interviewing 398 respondents from 37 villages. About 64.8% of respondents reported conflict in two major groups—crop damage (30.6%) and livestock depredations (6.2%), while 28% reported both. Conflict incidences were relatively high in summer and frequently occurred in areas closer to the forest (<500 m) and between the elevations range of 2700 m to 3000 m above sea level (asl). The dependency of locals on forest resources (70%) for their livelihood makes them vulnerable to HBC. The “upper lower” class respondents were most impacted among the various socioeconomic classes. Two of the four clusters were identified as HBC hot spots in Lahaul valley using SaTscan analysis. We also obtained high HBC in cluster II with a 14.35 km radius. We found that anthropogenic food provisioning for HBB, livestock grazing in bear habitats, and poor knowledge of animal behavior among the communities were the major causes of HBC. We suggest horticulture crop waste management, controlled and supervised grazing, ecotourism, the constitution of community watch groups, and others to mitigate HBC. We also recommend notifying a few HBB abundant sites in the valley as protected areas for the long‐term viability of the HBB in the landscape.

Population size, density, and ranging behaviour in a key leopard population in the Western Cape, South Africa.

Globally, leopards are the most widespread large felid. However, mounting anthropogenic threats are rapidly reducing viable leopard populations and their range. Despite the clear pressures facing this species, there is a dearth of robust and reliable population and density estimates for leopards across their range, which is particularly important in landscapes that consist of protected and non-protected areas. We conducted a camera trapping survey between 2017 and 2018 in the Western Cape, South Africa to estimate the occupancy, density, and population size of a leopard population. Leopards were recorded at 95% of camera trapping sites, which resulted in a high occupancy that showed no significant variation between seasons, habitat types, or along an altitudinal gradient. Our results indicated a low leopard density in the study area, with an estimated 1.53 leopards/100 km2 in summer and 1.62 leopards/100 km2 in winter. Mean leopard population size was therefore estimated at 107 and 113 individuals in the winter and summer respectively. Leopard activity centres for female ranges were centred in the core study area and could be predicted with good certainty, while males appeared to move out of the study area during winter which resulted in a higher uncertainty in locations of activity centres. Interestingly, livestock depredation events in the surrounding farmlands were significantly higher in winter, which coincides with male leopards moving outside the core protected area into the surrounding farmlands. To reduce livestock losses and retaliatory leopard killings, we suggest that human-carnivore conflict mitigation measures be intensely monitored during the winter months in the study area. We also suggest that future leopard conservation efforts should focus on privately-owned land as these non-protected areas contain the majority of the remaining suitable leopard habitat and may provide important dispersal corridors and buffer zones on which the long-term sustainability of leopard populations depends.

Drivers of predator-proof boma disrepair in the Amboseli Ecosystem, Kenya

AbstractAs natural habitats continue to shrink in Kenya's Amboseli Ecosystem, livestock depredation by lions Panthera leo threatens both the livelihoods of pastoralist communities and the lion populations affected by retaliatory killings. Finding ways for people and carnivores to coexist at the landscape scale is crucial to the long-term persistence of many threatened animal populations. The fortification of existing traditional bomas to make them predator-proof reduces night-time depredation of livestock. However, the sustainability and cost-effectiveness of such an initiative rely on boma owners taking responsibility for the upkeep and repair of their bomas. In August 2018 we surveyed 88 predator-proof bomas constructed during 2012–2018 and recorded their characteristics and levels of damage. We examined which variables influence disrepair, using a series of statistical analyses, including generalized linear mixed models. Our results reveal there was more disrepair in bomas constructed with wooden posts, confirming the benefit of using recycled plastic posts; in bomas with lower livestock density, suggesting that fewer animals could cause more damage or that such damage is not repaired; and in bomas located further away from a neighbouring predator-proof boma, suggesting a social element in encouraging or enabling boma owners to carry out maintenance. We recommend the consideration and further investigation of this social influence in guiding and improving the sustainability of conservation programmes that use predator-proof bomas, with a view to reducing negative interactions between pastoralists and lions.

Assessment of traditional techniques used by communities in Indian part of Kailash Sacred Landscape (KSL) for minimizing human-wildlife conflict

Communities living in Kailash Sacred Landscape India are often receiving damage from wildlife in the form of property damage, crop loss, and livestock depredation. This study was conducted to assess the use and effectiveness of traditional practices for minimizing human-wildlife conflict (HWC) by communities in KSL India. The fieldwork was carried out in four forest ranges in the Indian part of KSL where 584 respondents participated in interviews. The finding indicates that there are 16 types of traditional methods used by the KSL community in the area including guarding, fencing, night vigilance, scarecrow, and making noise. Around 61% of the respondents in KSL-India identified vigilance as an effective measure to mitigate HWC, while 14% of the people interviewed consider that vigilance by humans is not fully effective. A total of 36% of the respondents reported that the use of a guardian dog an effective measure to mitigate HWC while 47% of the respondents claimed that the use of a guardian dog is not fully effective. According to the respondents, only 20% said that fencing is effective to mitigate HWC while 10% disagreed, 15% neither agreed nor disagreed, 12% agreed while 42% strongly disagreed. Around 34% of the respondents agreed that the use of multiple deterrents is effective in mitigating HWC while 51% strongly disagreed, 0% agreed and 6% disagreed. The study underlines the importance of traditional practices used in KSL-India in mitigating human-wildlife conflict. It also found that traditional knowledge is being lost due to out-migration, reduced social cohesion and erosion of interest in traditional techniques.

Predicting carnivore habitat use and livestock depredation risk with false-positive multi-state occupancy models

The cycle of livestock depredation and retaliatory killing constitutes a major threat to large carnivores worldwide and imposes considerable hardships on human communities. Mitigation efforts are often undertaken with little knowledge of ecological underpinnings and patterns of depredation, limiting conservationists' ability to develop, prioritize, and evaluate solutions. Carnivore detection and depredation data from interviews in affected communities may help address this gap, but such data are often prone to false-positive uncertainty. To address these challenges in the Pamir Mountains of Tajikistan we collected snow leopard, lynx, wolf, and bear detection and depredation reports from local communities via semi-structured interviews. We used a novel hierarchical multi-species multi-state occupancy model that accounted for potential false-positives to investigate carnivore site use and depredation concurrently with respondents' apparent vulnerability to that risk. Estimated false-positive probabilities were small, but failure to account for them overstated site use probabilities and depredation risk for all species. Although individual vulnerability was low, depredation was nonetheless commonplace. Carnivore site use was driven by clear habitat associations, but we did not identify any clearly important large-scale spatial correlates of depredation risk despite considerable spatial variation in that risk. Respondents who sheltered livestock in household corrals reinforced with wire mesh were less likely to report snow leopard depredations. Reducing depredation and retaliation at adequately large scales in the Pamirs will likely require a portfolio of species-specific strategies, including widespread proactive corral improvements. Our approach expanded inference on the often-cryptic processes surrounding human-carnivore conflict even though structured wildlife data were scarce.
