Asiatic black bears (Ursus thibetanus) are a large carnivore, widely distributed in East, South, and Southeast Asia. However, they have experienced dramatic population decline across this range due to various anthropogenic threats. The great demand for bear parts in the black market exposes this species to intense pressure of being poached and then illegally traded. Meanwhile, the continuous expansion of anthropogenic land use results in the sharpening of human–bear conflicts. In this study, we conducted a comprehensive search and collected information of the poaching, illegal trade, and human–bear conflict events related to Asiatic black bears reported in China during 2010–2020. By systematically searching judicial adjudicative documents and news reports, we identified 351 (64 poaching, 221 illegal trade, and 90 conflict) events across the country. The results showed that Southwest China was a hotspot across all categories (41, 149 and 40 events, respectively). Bear paws were the most common type of bear parts found in illegal trade (52.1%), and the most frequently reported human–bear conflict form was human injury from bear attacks (at least 52 people injured and another 7 killed). By determining the status of black bears being poached, traded, and their conflicts with humans in China, these results will provide important insights into the further research and conservation of this iconic species.

Human activities significantly influence the changes in wildlife habitats and biodiversity, highlighting the necessity to enhance public knowledge, perceptions, and practices (KPP) to mitigate their consequences. Previous research suggests that many people in Bangladesh do not consider wildlife and biodiversity conservation a crucial issue. However, enhancing their KPP could be essential in developing effective and sustainable conservation efforts in Bangladesh. So, the current study aimed to evaluate the public’s KPP of wildlife conservation and biodiversity management in Bangladesh. A total of 3060 individuals’ data were collected from various sociodemographic backgrounds using a structured questionnaire followed by statistical analyses including Pearson’s chi-square, Spearman’s correlation, and logistic regression analysis, which were performed to assess the correlations and trends among variables using STATA and SPSS. The results revealed a significant heterogeneity in KPP across different sociodemographic groups. Importantly, the younger respondents (ages 21–30) indicated a high level of KPP, and respondents without formal education and belonging to older ages demonstrated markedly low levels of KPP. In the country’s divisional levels, respondents from Khulna and Rangpur revealed the highest and lowest KPP levels, respectively. Our study also revealed that students represented the major occupational demographic and displayed moderate levels of KPP. Notably, respondents highlighted the decline or absence of several wild animal species, including black bears, deer, vultures, wild cats, hanuman monkeys, and rhesus monkeys, from their local areas over the past decades. Public opinion on wildlife protection revealed 78.6% and 73.4% disapproving of hunting rejection and wildlife trading, respectively. Nonetheless, a lack of knowledge remained, as 16.89% of respondents were unaware of measures to alleviate human-wildlife conflict. The correlation analysis indicated a favorable association among KPP components, especially between knowledge and perception (correlation coefficient = 0.438), underscoring the essential influence of awareness on conservation actions. This study offers critical insights for developing interventions to enhance KPP among local communities and stakeholders, hence promoting sustainable wildlife conservation and biodiversity management in Bangladesh. Taken together, the findings provide baseline data for safeguarding biodiversity and fostering long-term wildlife sustainability in Bangladesh. Full article

Estimating the population density of vulnerable species, such as the elusive and nocturnal Asiatic black bear (Ursus thibetanus), is essential for wildlife conservation and management. We used camera traps and a Random Encounter Model (REM) to estimate the population density of U. thibetanus during the autumn and winter seasons in the Hindu Raj Mountains. We installed 23 camera traps from October to December 2020 and acquired 66 independent pictures of Asiatic black bears over 428 trap nights. Our results showed that the bears preferred lowland areas with the presence of Quercus spp. We estimated, using the REM, a population density of U. thibetanus of 1.875 (standard error = 0.185) per square kilometer, which is significantly higher than that in other habitats. Our results showed that during autumn and winter, the bear population density tends to concentrate at lower elevations. Forest cover showed a positive correlation with the rates of bear encounters unlike the Euclidean distance to human settlements, altitude, and aspect variables. The approaches used here are cost-effective for estimating the population density of rare and vulnerable species such as U. thibetanus, and can be used to estimate their population density in Pakistan. Population density estimation can identify areas where the bears live and human–bear conflicts occurred and use this information in future wildlife management plans. Full article

Our study assessed patterns of Asiatic black bear (Ursus thibetanus)–human conflicts within the Guthichaur rural municipality, Jumla, Nepal. Through semi-structured interviews with villagers, focus group discussions (FGDs), and key informant interviews (KIIs), we gathered black bear–human conflict information from 2009 to 2019. We identified three primary types of black bear–human interactions: crop damage, livestock depredation, and human injuries. Of these, crop damage (77.03%) emerged as the most prevalent issue. Notably, peak occurrences were observed during autumn (September–October) typically between 9 PM and 3 AM. Livestock depredations were more frequent during nighttime in April–August, with cows/ox (70.12%) being the most depredated animal. Our data also revealed five recorded cases of black bear attacks on humans, which transpired from September to October, primarily in farmland areas in varying years. Despite a prevailing negative perception of bears, a notable level of support exists for their conservation efforts among local communities. Furthermore, these conflicts could be mitigated by reinforcing indigenous crop protection methods and implementing targeted mitigation strategies, as observed in other regions with successful black bear–human interaction management.

Increasing human–bear conflicts are a growing concern, and managers often assume bears in developed areas are food-conditioned. We examined the relationship between human–bear conflicts and food conditioning by analyzing isotopic values of hair from black bears (Ursus americanus floridanus) involved in research (n = 34) and conflicts (n = 45). We separated research bears into wild and developed subgroups based on the impervious surface within their home ranges and separated conflict bears based on observations of human food consumption (anthropogenic = observations; management = no observations). We initially assumed wild bears were not food conditioned and anthropogenic bears were. However, using isotopic values, we classified 79% of anthropogenic bears and 8% of wild bears as food conditioned. Next, we assigned these bears to the appropriate food conditioned category and used the categorizations as a training set to classify developed and management bears. We estimated that 53% of management bears and 20% of developed bears were food conditioned. Only 60% of bears captured within or using developed areas showed evidence of food conditioning. We also found that δ13C values were a better predictor of anthropogenic foods in a bear’s diet than δ15N values. Our results indicate that bears in developed areas are not necessarily food conditioned and caution against management actions based on limited observations of bear behavior. Full article

Human wildlife conflict (HWC) impacts the livelihood of many rural communities worldwide. This study investigated the impact of HWC on people living near community forests (CF) in Nepal. Using databases provided by the Division of Forest Offices and data obtained from surveys between October 2019–March 2020, we quantified the financial loss of HWC to the local people. Between 2015 and 2019, 3315, or 27%, of the livestock owned by the survey respondents were killed by wild predators in the Kaski and Tanahun Districts. Chicken (Gallus spp.) was the most common prey taken (80%), followed by sheep (Ovis spp.) and goats (Capra spp.) (15%), cows (Bos spp.) (2%), pigs (Sus spp.) (2%), and buffalo (Bubalus spp.) (1%). Leopards (Panthera pardus) were the primary predators, followed by golden jackals (Canis aureus), jungle cats (Felis chaus), yellow-throated martens (Martes flavigula), and Himalayan black bears (Ursus thibetanus). The financial loss of livestock during this period was USD $115,656.00, equivalent to USD $142.61 per household. Crops were also damaged and eaten by wildlife, and 2165 crop-raiding events were recorded between 2015 and 2019. Rice (Oryza sativa), followed by maize (Zea mays), millet (Panicum miliaceum), and potatoes (Solanum tuberosum) were the main crops lost. Rhesus monkeys (Macaca mulatta) were the most common crop raiders, causing 74% of the damage, followed by Indian field mice (Mus booduga) (12%). From 2015 to 2019, crop losses equated to USD $83,424.00. Forest regeneration on abandoned agricultural land expanded wildlife habitats, enabling wild animals to come within reach of human settlements, which increased the likelihood of HWC events. Although the success of the community forest restoration program resulted in increased forest-cover, marginally increasing biodiversity, the reduced distance between human settlements and wildlife habitat, compounded by a lack of natural prey, may have unwittingly exacerbated HWC in this region. We recommend surveying predator and prey populations in the forest habitat, and implementing a habitat management program to improve prey populations within the community forests. Meantime, we propose establishing a financial relief and insurance program for crop and livestock losses at the local community level to alleviate any financial difficulties to the local communities caused by HWC.

Connectivity and wildlife corridors are often key components to successful conservation and management plans. Connectivity for wildlife is typically modeled in a static environment that reflects a single snapshot in time. However, it has been shown that, when compared with dynamic connectivity models, static models can underestimate connectivity and mask important population processes. Therefore, including dynamism in connectivity models is important if the goal is to predict functional connectivity. We incorporated four levels of dynamism (individual, daily, seasonal, and interannual) into an individual-based movement model for black bears (Ursus americanus) in Massachusetts, USA. We used future development projections to model movement into the year 2050. We summarized habitat connectivity over the 32-year simulation period as the number of simulated movement paths crossing each pixel in our study area. Our results predict black bears will further colonize the expanding part of their range in the state and move beyond this range towards the greater Boston metropolitan area. This information is useful to managers for predicting and addressing human–wildlife conflict and in targeting public education campaigns on bear awareness. Including dynamism in connectivity models can produce more realistic models and, when future projections are incorporated, can ensure the identification of areas that offer long-term functional connectivity for wildlife.

The “pot bears” received international media attention in 2010 after police discovered the intentional feeding of over 20 black bears during the investigation of an alleged marijuana-growing operation in Christina Lake, British Columbia, Canada. A two-phase random digit dialing survey of the community was conducted in 2011 to understand local perspectives on bear policy and management, before and after a summer of problem bear activity and government interventions. Of the 159 households surveyed in February 2011, most had neutral or positive attitudes towards bears in general, and supported the initial decision to feed the food-conditioned bears until the autumn hibernation. In contrast to wildlife experts however, most participants supported relocating the problem bears, or allowing them to remain in the area, ahead of killing; in part this arose from notions of fairness despite the acknowledged problems of relocation. Most locals were aware of the years of feeding but did not report it, evidently failing to see it as a serious form of harm, even after many bears had been killed. This underscores the importance of preventive action on wildlife feeding and the need to narrow the gap between public and expert opinion on the likely effects of relocation versus killing.
