From causes of conflict to solutions: Shifting the lens on human–carnivore coexistence research

AbstractHuman‐carnivore conflicts pose significant challenges in the management and conservation of carnivores across the globe. Abundant research has led to generalizable insights into the causes of such conflicts. For example, conflicts predictably occur when carnivores have access to human food resources, particularly when their natural foods are scarce. However, similar insights into the effectiveness of interventions aimed at coexistence remains comparatively scarce. We hypothesized that this disparity might be reflected in a bias toward research focused on causes of conflict rather than interventions to address it. To test our hypothesis, we evaluated the content of studies on human–carnivore conflicts and coexistence in Canada and the United States from 2010 to 2021. We found that studies disproportionately focused on causes of conflict, with that discrepancy increasing through our study period. We also found a disproportionate focus on black bears and wolves and western jurisdictions, and a disproportionate use of observational (vs. experimental) approaches. Studies on conflict interventions were primarily directed at the carnivores themselves (e.g., lethal approaches) versus human elements (e.g., attractant management, policies), despite evidence that the latter are more effective. We expect that a shift in focus toward solutions‐oriented research, integrating insights across geographies, taxa, social contexts, and disciplines, would facilitate effective interventions and foster coexistence, improving outcomes for people and carnivores alike.

A global assessment of large terrestrial carnivore kill rates.

Through killing and instilling fear in their prey, large terrestrial carnivores shape the structure and function of ecosystems globally. Most large carnivore species have experienced severe range and population declines due to human activities, and many are now threatened with extinction. Consequently, the impacts of these predators on food webs have been diminished or lost completely from many ecosystems. Kill rates provide a fundamental metric for understanding large carnivore ecology and assessing and comparing predation within and across ecological communities. Our systematic review of large terrestrial mammalian carnivore kill rates reveals significant positive geographic (North America, Europe, and Africa) and taxonomic (grey wolf Canis lupus, puma Puma concolor, lion Panthera leo, and Eurasian lynx Lynx lynx) bias, with most studies apparently motivated by human-carnivore conflict over access to ungulate prey and wildlife management objectives. Our current understanding of the behaviour and functional roles of many large carnivore species and populations thus remains limited. By synthesising and comparing kill rates, we show that solitary carnivores (e.g. brown bears Ursus arctos and most felids) exhibit higher per capita kill rates than social carnivores. However, ungulate predation by bears is typically limited to predation of neonates during a short period. Lower per capita kill rates by social carnivores suggests group living significantly reduces energetic demands, or, alternatively, that group-living carnivores defend and consume a greater proportion of large prey carcasses, or may acquire more food through other means (e.g. scavenging, kleptoparasitism) than solitary hunters. Kill and consumption rates for Canidae - measured as kilograms of prey per kilogram of carnivore per day - are positively correlated with body mass, consistent with increasing energy costs associated with a cursorial hunting strategy. By contrast, ambush predators such as felids show an opposite trend, and thus the potential energetic advantage of an ambush hunting strategy for carnivores as body mass increases. Additionally, ungulate kill rates remain relatively constant across solitary felid body sizes, indicative of energetic constraints and optimal foraging. Kill rate estimates also reveal potential insights into trophic structuring within carnivore guilds, with subordinate carnivores often killing more than their larger counterparts, which may be indicative of having to cope with food losses to scavengers and dominant competitors. Subordinate carnivores may thus serve an important role in provisioning food to other trophic levels within their respective ecosystems. Importantly, kill rates also clarify misconceptions around the predatory behaviour of carnivores (e.g. spotted hyaenas Crocuta crocuta and wolverines Gulo gulo are often considered scavengers rather than the capable hunters that they are) and thus the potential impacts of various carnivore species on their ecological communities. Despite the importance of kill rates in understanding predator-prey interactions, their utility is not widely recognised, and insufficient research limits our ability to fully appreciate and predict the consequences of modified predation regimes, justify current management actions affecting carnivores, or inform effective conservation measures. Together with other important research on predator-prey interactions, robust kill rate studies that address the research deficiencies we highlight will provide a deeper understanding of the foraging behaviours and potential ecosystem impacts of many of the world's carnivores, thus aiding effective conservation and management actions.

Dynamic primary resources, not just wild prey availability, underpin lion depredation of livestock in a savanna ecosystem.

Because it can lead to retaliatory killing, livestock depredation by large carnivores is among the foremost threats to carnivore conservation, and it severely impacts human well-being worldwide. Ongoing climate change can amplify these human-wildlife conflicts, but such issues are largely unexplored, though are becoming increasingly recognized. Here, we assessed how the availability of primary resources and wild prey interact to shape large carnivore selection for livestock rather than wild prey (i.e., via prey switching or apparent competition). Specifically, we combined remotely sensed estimates of primary resources (i.e., water availability and primary productivity), wild prey movement, and 7 years (2015-2021) of reports for livestock depredation by African lions (Panthera leo) in the Makgadikgadi Pans ecosystem, Botswana. Although livestock depredation did not vary between wet versus dry seasons, analyses at finer temporal scales revealed higher incidences of livestock depredation when primary production, water availability, and wild prey availability were lower, though the effects of wild prey availability were mediated by water availability. Increased precipitation also amplified livestock depredation events despite having no influence on wild prey availability. Our results suggest that livestock depredation is influenced by the diverse responses of livestock, wild prey, and lions to primary resource availability, a driver that is largely overlooked or oversimplified in studies of human-carnivore conflict. Our findings provide insight into tailoring potential conflict mitigation strategies to fine-scale changes in resource conditions to efficiently reduce conflict and support human livelihoods.

Did we achieve what we aimed for? Assessing the outcomes of a human–carnivore conflict mitigation and coexistence project in Europe

Monitoring and evaluation practices, demanded by nature conservation project donors, often focus on practical outputs, leaving the assessment of intended short and medium‐term outcomes and long‐term impacts challenging. This study employs a merger of the conflict intervention triangle model (CITM) and its three dimensions relationship, substance, and process, together with the logical framework approach (LFA) within the context of a human–wildlife conflict and coexistence (HWCC) project (LIFE EuroLargeCarnivores) in order to assess project correlated outcomes on stakeholder level over time.Two stakeholder surveys were conducted across 14 project partner countries, capturing baseline perceptions in 2018 and assessing changes in 2021. To assess the actual influence of the project with its focus on conflict mitigation, we applied an ex post counterfactual analysis. Results indicate positive developments in all dimensions of the CITM. The influence of the project is demonstrated by statistically significant differences in response behavior between participants and non‐participants of project interventions. The overall outcome regarding beliefs in satisfactory future management of increasing large carnivore populations, is more intricate. Significant differences are observed among three selected main stakeholder categories over the project's timeframe. While nature conservationists maintain high confidence levels, confidence of hunters and livestock raisers declined. However, results for participants of project interventions depict a significantly lower decline in confidence compared to non‐participants. Based on our findings, we provide insights how to efficiently evaluate outcomes of HWCC projects, offering recommendations for wildlife conservation practitioners. We conclude that HWCC projects are important also and especially in times of unfavorable frame conditions. Rigorous evaluation methods are essential to ensure efficient use of resources in order to maximize the outcomes of HWCC projects. The study highlights the need for long‐term evaluation to assess broader impacts at country, regional, and sector levels.

Scaling issues in the study of livestock depredation by carnivores

ContextMany studies have documented the magnitude and socioecological drivers of livestock depredation, yet few have assessed how observations of depredation might vary with spatiotemporal scale. Understanding scaling relationships may allow for more accurate aggregation of observations collected across diverse extents and resolutions to better inform management actions.ObjectivesHerein we examine how reported metrics of livestock depredation varied by spatial and temporal scale (extent and resolution) after controlling for other drivers of differences among studies.MethodsFrom 213 published studies we extracted conflict metrics (i.e., number of animals killed, number of attack incidents, and percent annual loss of stock) and regressed each against spatiotemporal extent (i.e., size of study area, duration of study) and resolution (i.e., minimum mapping unit, frequency of observations) while controlling for potential biases.ResultsThe number of attacks or animals killed was positively related to spatial and temporal extent whereas percent annual loss of stock declined with extent. Further, the effects of scaling variables were modified through interactions with other factors (e.g., human density) known to influence human-carnivore conflict. The data available for spatiotemporal resolution were too sparse to draw conclusions. While scaling relationships were generally linear, they became increasingly noisy at broader extents.ConclusionsConsistent with other ecological investigations, the scale of observation influenced the observed outcomes in human-carnivore conflict metrics. Authors should report the spatiotemporal dimensions of their observations to improve robust inference in comparative studies. Enhanced understanding of scaling relationships in human-carnivore conflict metrics should improve strategic allocation of resources to better mitigate future conflict.

Farmers’ perceptions of coexisting with a predator assemblage: Quantification, characterization, and recommendations for human-carnivore conflict mitigation

Human-Carnivore Conflicts (HCC) are a critical concern for the conservation of both species and habitats, as well as the livelihoods of farmers. This underscores the need for comprehensive research that examines how farmers perceive their interactions with wildlife. Our study aims to present three strategies for dealing with HCC to policymakers, state or regional authorities, and farmers. These strategies are based on a thorough examination and categorization of how farmers view their interactions with a diverse group of predators. Due to an ongoing HCC between farmers at northern Israel and local carnivore species we conducted an online survey with 46 farmers from this region and utilized an in-depth Exploratory Factorial Analysis to identify potential solutions to mitigate conflicts between humans and carnivores. Our findings unveiled the complex nature of these interactions from the farmers’ perspective. They stressed the importance of achieving a delicate equilibrium between wildlife conservation and farmers’ requirements. Through our analysis, we identified three key strategies that farmers perceive as effective in reducing Human-Carnivore conflicts: 1. The implementation of compensation schemes and improved collaboration between farmers and authorities; 2. Advancements in Research and Development (R&D) and the utilization of technological solutions; 3. A preference for simple, low-tech solutions. These strategies offer a valuable framework for authorities and policymakers to assess conflict mitigation options. Furthermore, our study shed light on the relatively low level of trust that farmers have in major wildlife management authorities and governmental offices. This highlights the significance of incorporating farmers’ perspectives and strategies into human-wildlife interaction management plans, while also building trust, to foster stronger relationships that benefit both wildlife conservation and farmers’ livelihoods.

Predictions & perceptions: A social-ecological analysis of human-carnivore conflict in Botswana

Human-carnivore conflict in agrarian landscapes poses a significant threat to both large carnivore populations and human livelihoods. Conservation strategies aimed at mitigating conflict often rely primarily on ecological, landscape-scale factors. However, assessing the influence of microhabitat, as well as local variation in human perceptions, can offer valuable insights into the spatial patterns of human-carnivore conflict. The objectives of this study were to identify landscape predictors of livestock depredation risk, characterize microhabitat vegetation patterns at kill sites, and assess the spatial alignment between ecologically-predicted and human-perceived depredation risk. Through use of predation risk modeling, microhabitat pattern analysis, and participatory mapping exercises, we provide insight into the spatial patterns of livestock depredation risk from a multi-carnivore guild in an agrarian landscape located in the Makgadikgadi region of Botswana. We identified 170 depredation events and conducted 63 participatory mapping exercises across community lands situated between two wildlife protected areas. Results indicated anthropogenic landscape variables as the primary drivers of general depredation risk. Notably, distinct spatial patterns emerged between African lion (Panthera leo) and African wild dog (Lycaon pictus) depredation, underscoring the need for species-specific conservation strategies. Microhabitat analysis indicated a preference for lower vegetation cover within the multi-predator guild, suggesting livestock microhabitat risk-mitigation behaviors outweigh predator hunting strategies. While human perceptions generally aligned with ecologically predicted risk, identified divergences emphasize the importance of tailored conflict mitigation strategies to accommodate varying influences. Overall, the findings advocate for species-specific depredation risk analyses and the inclusion of human perceptions for a comprehensive spatial understanding of livestock depredation risk.

Livestock Depredation by Large Carnivores and Human-Wildlife Conflict in Two Districts of Balochistan Province, Pakistan.

Livestock herding is a vital practice in Balochistan, contributing to the economy and culture. The livestock sector is significant in Balochistan, providing 20% of the national stock. Large predators and their prey species, including livestock, have coexisted in these mountainous landscapes for centuries. The aim of the present research is to investigate the impacts of livestock depredation by large predators on livelihoods and predator conservation in two districts of Balochistan, Pakistan. A human-carnivore conflict survey was conducted from July to September 2019, collecting data from 311 residents in a selected study area. Large predators in the study area preyed on a total of 876 livestock during a one-year period, including 560 goats, 292 sheep, 19 cows, and 5 donkeys. The gray wolf is the leading predator, responsible for 66.3% of livestock depredation, followed by the caracal (24.3%), Asiatic jackal (8.9%), and striped hyena (0.6%). The total economic loss was USD 78,694. Overall, 80% of respondents had a negative perception of wolves compared to 24.4% for caracals. Only 20.6% of respondents knew about the importance of conserving carnivores. Livestock depredation by carnivores in the study area created a negative perception of these animals among people. There is a lack of awareness about the importance of conserving carnivore species and their role in the ecosystem. This lack of understanding has ultimately led to detrimental effects on predator populations. It is imperative to raise awareness among people about the ecological significance of carnivores through community meetings, seminars in educational institutions, and providing basic education to herders about effective livestock guarding practices.

Social-ecological predictors of spotted hyena navigation through a shared landscape.

Human-wildlife interactions are increasing in severity due to climate change and proliferating urbanization. Regions where human infrastructure and activity are rapidly densifying or newly appearing constitute novel environments in which wildlife must learn to coexist with people, thereby serving as ideal case studies with which to infer future human-wildlife interactions in shared landscapes. As a widely reviled and behaviorally plastic apex predator, the spotted hyena (Crocuta crocuta) is a model species for understanding how large carnivores navigate these human-caused 'landscapes of fear' in a changing world. Using high-resolution GPS collar data, we applied resource selection functions and step selection functions to assess spotted hyena landscape navigation and fine-scale movement decisions in relation to social-ecological features in a rapidly developing region comprising two protected areas: Lake Nakuru National Park and Soysambu Conservancy, Kenya. We then used camera trap imagery and Barrier Behavior Analysis (BaBA) to further examine hyena interactions with barriers. Our results show that environmental factors, linear infrastructure, human-carnivore conflict hotspots, and human tolerance were all important predictors for landscape-scale resource selection by hyenas, while human experience elements were less important for fine-scale hyena movement decisions. Hyena selection for these characteristics also changed seasonally and across land management types. Camera traps documented an exceptionally high number of individual spotted hyenas (234) approaching the national park fence at 16 sites during the study period, and BaBA results suggested that hyenas perceive protected area boundaries' semi-permeable electric fences as risky but may cross them out of necessity. Our findings highlight that the ability of carnivores to flexibly respond within human-caused landscapes of fear may be expressed differently depending on context, scale, and climatic factors. These results also point to the need to incorporate societal factors into multiscale analyses of wildlife movement to effectively plan for human-wildlife coexistence.

The behaviours of different carnivore and livestock species shape spatial patterns of human–carnivore conflict

Abstract Understanding the ecological and human factors that shape the loss of livestock to wild carnivores can help target conservation efforts. We used 5 years of livestock depredation records (2009–2013, n = 1147) alongside Hwange National Park, Zimbabwe, to investigate how spatial patterns vary by carnivore and livestock species. Dominant patterns across all species and seasons included an increased likelihood of depredation closer to protected areas (core carnivore habitat) and in more open areas closer to human settlements (where livestock are most abundant). Lions were less likely than spotted hyenas to attack livestock further from protected areas, while goat and donkey depredation was more concentrated around homesteads compared to cattle depredation. Leopards were more likely than other predators to attack livestock in areas of higher human density and nearer water sources, likely reflecting their preference for goats and sheep which generally remain near homesteads unless taken to watering holes. Carnivores make trade‐offs between attacking livestock where it is most available (near human settlements) and where the risk of detection and retaliation by humans is lower (nearer protected areas, in more wooded habitats, and further from human activity). These results have helped target local mitigation strategies. They may also inform human–wildlife conflict mitigation at other sites globally by highlighting the need to understand species‐specific differences in conflict patterns and tailor solutions accordingly.

Tradeoffs between resources and risks shape the responses of a large carnivore to human disturbance

Wide-ranging carnivores experience tradeoffs between dynamic resource availabilities and heterogeneous risks from humans, with consequences for their ecological function and conservation outcomes. Yet, research investigating these tradeoffs across large carnivore distributions is rare. We assessed how resource availability and anthropogenic risks influence the strength of lion (Panthera leo) responses to disturbance using data from 31 sites across lions’ contemporary range. Lions avoided human disturbance at over two-thirds of sites, though their responses varied depending on site-level characteristics. Lions were more likely to exploit human-dominated landscapes where resources were limited, indicating that resource limitation can outweigh anthropogenic risks and might exacerbate human-carnivore conflict. Lions also avoided human impacts by increasing their nocturnal activity more often at sites with higher production of cattle. The combined effects of expanding human impacts and environmental change threaten to simultaneously downgrade the ecological function of carnivores and intensify human-carnivore conflicts, escalating extinction risks for many species.

Straight from the coyote's mouth: genetic identification of prey through oral swabs of predators

Human–carnivore conflicts often involve the depredation of domestic livestock. These depredation events are rarely observed, yet mitigation typically involves identifying the species or individual involved for removal or relocation. We tested a molecular method to identify individuals involved in depredation events using mouth swabs to determine if prey DNA could be detected, and for how long. We fed mule deer Odocoileus hemionus meat to captive coyotes Canis latrans and swabbed their mouths at five predetermined intervals between 2–72 h after consumption of the deer meat. We assessed two different molecular forensic methods to analyze the saliva swabs: qPCR for species identification and microsatellites for individual prey identification. We found that qPCR analysis was highly effective, detecting the deer DNA in the coyote saliva for up to 72 h post‐deer consumption. Our results suggest that if an individual carnivore suspected of livestock depredation is captured within 72 h of a depredation incident, it is possible to confirm their potential involvement with a buccal swab and qPCR analysis. Utilizing this method could aid in more targeted and effective removal of individual problem carnivores as opposed to widespread removal of involved species.

Dog in sheep’s clothing: livestock depredation by free-ranging dogs may pose new challenges to wolf conservation

Livestock depredation is a common cause of human-carnivore conflicts. In Portugal, free-ranging dogs are increasingly abundant and overlap endangered Iberian wolf territories, with reports of livestock depredation. However, the lack of awareness about dogs’ possible role as predators leads to bias against wolves in cases of damages. Our goal was to assess and compare wolf and free-ranging dog’s diet composition at southern wolf range in Portugal, to offer insights on dogs’ predatory role on livestock and its implications for the conservation of an endangered wolf subpopulation. We assessed diet composition from 107 to 95 genetically confirmed wolf and dog scats, respectively, and complemented the analysis with data from 40 attacks on livestock with successful genetic predator assignment. Scat analysis highlighted goats as the most consumed dog prey in all analysed regions, with lagomorphs, small mammals, and wild boars as second most consumed in each region, respectively. Wolves mainly relied on goats and wild boars in the west, whereas in the central region they mostly fed on birds. The dietary overlap between both canids was very high (Pianka’s index O = 0.93), showing potential for competition. Additionally, we found that dogs were the sole predators detected in most attacks (62%). Our findings highlight dogs’ role as predators of livestock, and possibly also wild species, posing a further challenge to wolf conservation. Alongside adequate husbandry practices, we emphasise the need for a stronger enforcement of the legislation on dog ownership and an effective management of the stray population to reduce human-wolf conflict.

Assessing human–carnivore conflict and the identification of hotspot areas to prioritize mitigation efforts

ABSTRACT Human‒carnivore conflict (HCC) is a worldwide conservation challenge. A multi-method approach was used to assess the perceived threats posed to human life or property by carnivores and determine the effects of socio-demographic and environmental factors on HCC in south-western Iran. Results showed that red foxes, gray wolves and honey badgers were the main species responsible for the conflict. People with higher education were less likely to kill carnivores or report negative attitudes toward them. Human alterations of natural habitats are responsible for the majority of HCC, with an anthropogenic factor (distance to cropland) as the top predictor. Villages with the highest probability of conflict were located in proximity to national parks. The presence of landfill sites in proximity of human settlements and improper waste disposal methods may increase HCC. Focusing mitigation measures on high-risk areas can potentially reduce conflicts and lead to a decrease in retaliatory killings of predators.

Spatio-temporal patterns of human-carnivore conflict and mitigation in Pakistan

Human-carnivore conflict is a noteworthy rural livelihood issue as livestock of local communities living around protected areas are depredated by wild carnivores, which are the persecuted by local communities, in response. The current study aimed at investigating the patterns, perception, economic losses, and mitigation of human wildlife conflict in Pakistan through meta-analysis of published literature and using the questionnaire survey method. We retrieved data from the published and unpublished sources, and from records of provincial wildlife departments. In addition, we also collected empirical data from different households falling in the range of targeted carnivore species and filled 331 semi-structured questionaries. Based on the activities and home range of the predator species, conflict density maps for each predator species were developed. Our analysis revealed that five major carnivore species are involved in the human-wildlife conflict, namely Asiatic black bear (Ursus thibetanus), Himalayan brown bear (Ursus arctos), common leopard (Panthera pardus), grey wolf (Canis lupus) and snow leopard (Panthera uncia). About 7214 livestock heads were reportedly lost during past two decades because of these five carnivore species. The domestic goat depredation was maximum (51.08 %, n = 3685), followed by sheep (27.09 %, n = 1954), cow (11.37 %, n = 820), buffalo (2.34 %, n = 169), dogs (2.05 %, n = 148), poultry (0.87 %, n = 63), donkey (4.28 %, n = 348), and horse (0.37 %, n = 27), causing a total financial loss of USD 1.87 million. Maximum livestock depredation occurred in summer season (50.79 %), at night (59.92 %) time and outside the village (51.22 %). Majority of the people showed negative attitude towards the predators, and they did not know about the conservation status and the authorities to report for conservation of the predator species. Most of the respondents were unaware about the possible management of the predator species for the co-existence of human and wildlife in the same landscape. However, majority of respondents (38.3 %) thought that livestock depredation by carnivore species can be controlled through payment of insurance compensation to the person who lost its livestock during carnivore attacks, followed by restoration of natural habitat (20.1 %), translocation of predator (16 %), and improved husbandry practices like predator proof corals (8 %). The study concludes that buffer zones of the protected areas are the hotspots for human- wildlife conflict and to avoid such conflict in future, special mitigation measures should be adapted, and regulations should be developed to minimize the niche overlap of the livestock and wildlife prey species, thereby to avoid any competition for food resources.

The influence of superstitions and emotions on villagers' attitudes towards striped hyena in southwestern Iran.

The intensity of human-carnivore conflict in socio-ecological systems may primarily be determined by people's attitudes and perceptions of carnivore-related threats. Direct or indirect threats posed by large carnivores to human interests may eventually lead to negative attitudes that can trigger retaliatory bahaviour against them. We studied local people's attitudes towards striped hyena (Hyaena hyaena), the nature and extent of the human-hyena conflict, and the socio-cultural drivers of the conflicts in 19 rural communities in southwestern Iran. We employed structural equation modelling to assess socio-cultural factors affecting attitudes towards striped hyenas. The findings of 300 interviews showed significant differences in local people's superstitious attitudes regarding gender, age, and education. More than 40% of the participants had encountered hyenas, and on average, each respondent lost 0.44 livestock in the past five years due to hyena attacks. However, livestock depredation by the hyena was low (13.3%) compared to the damage inflicted by all carnivores (73%). While the respondents indicated some degrees of fear, hatred to hyena was relatively low and they generally showed positive attitudes towards the species. Women and older people expressed the highest and respondents with higher education the least superstitious beliefs. Attitude score of respondents toward hyenas was correlated negatively with hatred for hyenas and positively with knowledge about them, but socio-demographics effects on attitudes towards hyenas were not statistically significant. Self-reported livestock loss was a relatively good predictor of hatred and fear. Herders who had not protected their livestock reported carnivore attacks at least once. We conclude that superstitions can potentially negatively affect hyena persistence, but can be reduced by improving the educational level of local people.

Factors affecting the recovery of Mexican wolves in the Southwest United States

Abstract Recovering and maintaining large carnivore populations is a global conservation challenge that requires better knowledge of the factors affecting their populations, particularly in shared landscapes (i.e. non‐protected areas where people occupy and or utilize the land). The Mexican wolf (Canis lupus baileyi) is an endangered wolf subspecies being recovered on shared landscapes in the Southwest United States and Mexico. We used data from the U.S. program to model population growth, evaluate the impact of management removal and illegal killing relative to other demographic factors, and test hypotheses about factors influencing rates of management removal and illegal killing. From 1998 to 2019, the population growth averaged 12% per year. Rates of natural reproduction, illegal killing and other mortality remained consistent over the 22 years; while releases, translocations and management removals varied markedly between two time periods, phase 1:1998–2007 and phase 2:2008–2019. The number of wolves removed for conflict management was higher during phase 1 (average ~ 13 per year, rate = 24.8%) than phase 2 (average of ~5 per year, rate = 5.2%). This decrease in management removal resulted in the wolf population resuming growth after a period of population stagnation. Two factors influenced this decrease, a change in policy regarding removal of wolves (stronger modelling support) and a decrease in the number of captive‐reared adult wolves released into the wild (weaker modelling support). Illegal mortality was relatively constant across both phases, but after the decrease in management removal, illegal mortality became the most important factor (relative importance shifted from 28.2% to 50.1%). Illegal mortality was positively correlated with rates of reintroduction and translocation of wolves and negatively correlated with the rate of management removal. Synthesis and applications. Using management removal to reduce human–carnivore conflict can have negative population impacts if not used judiciously. Recovering and maintaining carnivore populations in shared landscapes may require greater tolerance of conflict and more emphasis on effective conflict prevention strategies and compensation programs for affected stakeholders.

Post-conflict movements of polar bears in western Hudson Bay, Canada

Human–carnivore conflicts have increased as habitat has been affected by development and climate change. Understanding how biological factors, environment, and management decisions affect the behaviour of animals may reduce conflicts. We examined how biological factors, sea ice conditions, and management decisions affected the autumn migratory movement of polar bears ( Ursus maritimus Phipps, 1774) from 2016 to 2021 following their capture near Churchill, Manitoba, Canada, and release after a mean of 20 days (SE 2) in a holding facility. We deployed eartag satellite transmitters on 63 bears (26 males, 37 females), with 49% adults (>5 years old), 48% subadults (3–5 year old), and 3% <2-year old. We compared variation in on-ice departure of bears released post-conflict (conflict) to adult females without a conflict history (non-conflict). Conflict bears departed 89 km further north (mean = 59.7°N, SE 0.2) of non-conflict bears (mean = 58.9°N, SE 0.1). Bears released later during the migratory period were less likely to re-enter a community at a rate of 5.9%–6.4% per day. Of 69 releases (6 individuals requiring multiple releases), 12 bears re-entered Churchill and 13 entered Arviat, Nunavut. We suggest that the holding facility was effective at preventing additional conflicts and individuals with a high likelihood of recidivism should be held longer.

Fencing affects movement patterns of two large carnivores in Southern Africa

The erection of peripheral fences around protected areas has been shown to adversely affect the movement behavior, genetic connectivity and long-term viability of animal populations. However, fencing is also used extensively to reduce human encroachment, limit poaching activities, and mitigate human–wildlife conflicts. Limited information on the movement behavior of carnivores is available along the periphery of protected areas, particularly in semi-arid environments. To quantify the potential effects of the 824 km perimeter fence surrounding the Etosha National Park (Etosha, Namibia) on the movement and space use of carnivores, we collected GPS movement data from 36 lions (Panthera leo) and seven spotted hyenas (Crocuta crocuta) over a 14-year period. For these two apex carnivores, we measured the impact of the Etosha fence on their movements (step lengths and path straightness), calculated the likelihood of fence crossings, and evaluated the spatial–temporal characteristics of these crossings. Our results indicated that lions and hyenas moved faster (longer step lengths) when closer to the fence. Lions showed no variation in path straightness with respect to the fence but hyenas had straighter movement paths when closer to the fence. When moving within the vicinity of the fence, lions had a 9% likelihood of crossing the fence, while hyenas were much more likely (18%) to do so, which suggests that the Etosha fence was more permeable for hyenas than for lions. Fence crossings predominantly occurred at night for both species. Lions were more likely to cross the fence during the cold dry season (May–August) whereas hyenas crossed more often during the warm wet season (December–April). Female and adult lions had a higher probability of crossing the fence than males and subadults. These findings could be useful in the development of appropriate strategies to mitigate human–carnivore conflicts and thus promote the conservation of carnivores in multiple-use areas along the periphery of the park. Further research is needed to better elucidate the impact of perimeter fences on a broader suite of carnivores and other large mammals, including species-specific variation in the response to fences, as well as the economic benefits of fencing provided to local communities.
