Sloth bears (Melursus ursinus) rely on dens for reproduction, cub-rearing and shelter. Yet their denning ecology remains poorly studied, particularly in Gujarat – India. This new project by the WCB Research Lab and funded by Bears in Mind since 2025, aims to investigate sloth bear den site selection in northern Gujarat, encompassing both protected areas Jessore and Balaram-Ambaji Wildlife Sanctuaries (WLS) and human-disturbed forests (Polo Forest and surrounding areas of sanctuaries).
By examining habitat characteristics, terrain features, and human disturbances, this study will identify key factors influencing den selection. Data collection will include field surveys, sign identification and camera trapping to confirm den usage. Environmental parameters such as slope, aspect, vegetation type, and forest cover will be recorded, along with spatial proximity to water sources, roads, and settlements. Mapping and statistical analyses, including Generalized Linear Mixed Models (GLMM), will be used to evaluate habitat suitability.
The findings will contribute to conservation planning by identifying critical denning habitats and assessing risks posed by human activities. This research will provide science-based recommendations for habitat management and conflict mitigation, supporting long-term conservation efforts for sloth bears in Gujarat.
All species of bears are threatened by illegal trade for their parts, used as trophies, for consumption and for use in traditional medicines. The experts at Monitor Conservation Research Society (Monitor) have carried out research and enforcement support to counter the illegal trade in bears, especially, but not limited to, Asia, over the past few decades. One of the greatest obstacles in countering the illegal international trade in bear parts and derivatives is the lack of effective use of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). With 185 members, CITES is the world’s leading convention in place to regulate and control the international trade in wildlife – including all eight species of bears. Conf. 10.8 (Rev. CoP14) in 2007, noted that
“the continued illegal trade in parts and derivatives of bear species undermines the effectiveness of the Convention and that if CITES Parties and States not-party do not take action to eliminate such trade, poaching may cause declines of wild bears that could lead to the extirpation of certain populations or even species”
and recognised that
“long-term solutions for the protection and conservation of bears require the adoption of substantive and measurable actions.” It further urged parties to carry out a number of actions and recommended that Parties “review and strengthen measures, where necessary, to enforce the provisions of the Convention relating to specimens of species included in Appendices I and II, where bear parts and derivatives are concerned and further that Parties and States not-party, as a matter of urgency, address the issue of illegal trade in bear parts and derivatives.”
Monitor has found that at least some Parties to the Convention involved in illegal and/or unsustainable trade in bear parts and derivatives have not taken significant actions to address this problem or to follow up on the recommendations of Conf. 10.8 (Rev. CoP14). There has been no systematic review of the actions taken by Parties on this matter and therefore no accountability. The team has secured funds from Bears in Mind to allow them, working with partners, to investigate this issue and to carry out a review of actions prior to the coming Conference of the Parties of CITES, which will be held in Uzbekistan in November 2025.
We believe that the effective implementation of Conf. 10.8 (Rev. CoP14), and the continued monitoring of progress on this issue is absolutely essential to making CITES an effective tool for bear conservation and that the lack of implementation not only undermines the Convention but also undermines efforts and opportunities to ensure international illegal and unsustainable trade is not a threat the conservation of bears.
The Sloth bear population is declining across their distribution range due to habitat degradation, habitat loss, and facing conflicts with humans. These threats are expected to accelerate with increasing urbanization and demand for natural resources. Over the past decade, human interference in their habitats has led to a rise in Human-Sloth bear conflict in India.
Rajasthan, the largest state in India, has limited scientific data on Sloth bears. Existing studies focus mainly on distribution, diet within a single protected area, and local perceptions of the species. These studies highlight the urgent need for further research due to increasing poaching and habitat degradation. This study, supported by Bears in Mind since 2024, aims to investigate occupancy, genetic variability, and population structure across southern Rajasthan in the known distribution range of Sloth bear with an aim to identify local, landscape and genetic data and also contribute to the IUCN Bear Specialist Group’s project on Asian bears range mapping.
Only about 17% of the estimated 17,000 km2 of Sloth bear (Melursus ursinus) habitat in Nepal is effectively protected. The unprotected Sloth bear populations are largely confined to the forests of the Churia hills. In the eastern part of the Churia range lies the Trijuga forest which was once a stronghold for Sloth bears, but now faces unprecedented threats.
The team of WILD CARE (Wildlife Conservation and Research Endeavour Nepal) has gained extensive knowledge over the past three years in this area, and it revealed high levels of human disturbance, resulting in low bear density, patchy distribution, and intense conflicts, pushing bears to the brink of local extinction. Having obtained baseline data, the challenge now is improving locals’ awareness, perceptions and ability to coexist harmoniously with sloth bears and foster support for conservation.
This project, supported by Bears in Mind since 2024, is developed to address this challenge through (i) extensive awareness campaigns in local communities and schools, (ii) sensitization of local-level decision makers to include the needs of Sloth bears in forest use/management guidelines, and (iii) empowerment of community forest members on Sloth bear monitoring. By bridging the gap between scientific research and community engagement, the project offers hope for the long-term survival of Sloth bears in this critical habitat.
Sloth bears (Melursus ursinus) are one of the umbrella species that play an important role for the ecosystem, and is now considered as Vulnerable as per IUCN. The major reason for the continuous decline in its population is habitat degradation and fragmentation due to human settlements and anthropogenic pressures. This has resulted in loss of genetic exchange and hence functional connectivity. If it continues at the same rate, there will only be groups of isolated populations of Sloth bears with very low genetic diversity and high risk of inbreeding depression, ultimately resulting in extinction.
An earlier study by Thatte et al. (2019) highlighted the negative impact of human settlements and landscape features on Sloth bear functional connectivity. Another study by Dutta et al. (2015) also highlighted the importance of corridors for Sloth bears in Satpura-Maikal Landscape. In this project, the team wishes to investigate genetic diversity, gene flow and population structure in the western part of Maharashtra that will include three protected areas; Melghat Tiger Reserve, Yawal Wildlife Sanctuary and Gautala Wildlife Sanctuary. There has been information to connect these areas through corridors based on movement of tigers, but none of the studies have been carried out to identify the functional connectivity in this region.
This study, co-funded by Bears in Mind and the IBA since 2024, investigates the effect of landscape features on functional connectivity among Sloth bear populations in the Melghat landscape, India.
Gut microbial diversity of Asian bears is poorly studied; most studies have been conducted on brown bears and other European and American bear species. The goal of this research project by the Wildlife and Conservation Biology (WCB) Research lab is to study the gut microbial diversity of wild and captive Sloth bears in order to understand and compare microbial diversity.
The scat samples of wild sloth bears will be collected from Jessore wildlife sanctuary, in Gujarat state, which is known for the high density of Sloth bears in India. The samples of captive sloth bears will be collected from various zoos and bear rescue facilities in India. Fresh scats will be collected in a sterile bottle containing normal saline solution, and the microbial isolation will be carried out by conventional microbiological methods. Further identification will be done using Vitek-2 compact, an automated rapid identification system used for microbial identification. Genotypic analysis will be performed using 16s rRNA analysis by Sanger sequencing, followed by data analysis using BLASTN.
Microbiome biology is currently a relatively unexplored subject in conservation biology, but it has immense promise for understanding the effects of habitat degradation and nutrient availability. The findings will help to the zoos worldwide where the Sloth bears are kept and the State Forest Department to understand the health status of wild Sloth bears and their seasonal nutritional requirements.
Criminals use the Netherlands to operate a network of illegal trade in traditional Chinese medicines (TCM) that contain endangered animals and plants. This is shown in a joint project and investigation by Dutch foundations SPOTS, IUCN NL, Bears in Mind and internationally-known Earth League International (an authority on criminal networks behind illegal wildlife trade). The findings of their investigation is shocking.
IUCN NL, stichting SPOTS, Bears in Mind and Earth League International (ELI) initiated a project to establish whether there is a market in the Netherlands for TCM containing illegally used and traded (wild) animal parts and, if so, how these (wild) animal parts are smuggled into the Netherlands. On behalf of these organizations ELI was commissioned to investigate this trade. The intelligence-led operations started in September 2021 and ended in December 2022 and aimed to compile and analyze information on the trafficking routes, the main destinations, modus operandi and the key drivers. These findings were shared with the Netherlands Food and Consumer Product Safety Authority (NVWA) in 2023. They started a follow-up investigation, several warehouse searches were done, seizures made and an arrest took place. The investigation is still ongoing.

According to the latest TRAFFIC report on seizures of CITES-listed wildlife in the EU in 2022, the most frequently seized commodity type was medicinals (plant-and animal-derived medicinals which comprises medicines, extracts and cosmetics); accounting for 1,058 seizure records (29% of the total 2022 seizures). Animal-derived medicinals in 2022 accounted for 17% of the medicinals trade. Trade continued in medicinal products containing i.e. seahorse, venomous snakes, musk deer and sturgeon. But also bears Ursidae spp. (App. I,II/ Annex A,B). With 18% of the total seizures in CITES-listed wildlife in the EU, the Netherlands takes the second position after Germany (25%).
IUCN NL, stichting SPOTS, Bears in Mind and ELI also wish to raise awareness among politicians and the wider public in the Netherlands about the issues and impact this trade of illegal TCM has on specific species.

Sloth bears (Melursus ursinus) are distributed across the lowlands of Nepal. Despite being categorized as vulnerable, this species still does not receive sufficient attention for its conservation. Furthermore, sloth bears can play a significant role in balancing ecosystems by consuming harmful insects.
The aim of this study by the Environment Protection and Study Center (ENPROSC) is to address the lack of information about Sloth bears, focusing on areas with high bear populations but inadequate research. To collect field data, a grid of 2×2 square kilometres will be established within the forest. 30 camera trapping grids will be chosen using an alternate grid layout for 15 days. This technique will be set up for three times more in different grids, resulting in a total coverage of 120 grids for camera trapping in the study area. Additionally, a questionnaire survey will be conducted in Lamahi, Rapti, Rajpur and Gadhawa. Further analysis will be conducted using appropriate model and techniques.
The project’s expected outputs include baseline study report, a human-bear conflict status and a management plan to the conservation of sloth bear. This project endeavours to bridge knowledge gaps, provides new insights besides the protected areas, and contribute to the overall ecological well-being of the study area. Bears in Mind has financially contributed in the project.
The status of Sloth bears (Melursus ursinus) outside of protected areas in Nepal is unclear. This new project supported by Bears in Mind aims to investigate Sloth bear distribution, habitat use and conservation threats for the first time in a critical corridor of Lumbini Province.
Anecdotal records of bear signs, seizure of bear skin and bile, and very recent capturing of a bear cub in retaliation to a conflict event suggest a threatened Sloth bear population. Therefore, this project seeks to break barriers to Sloth bear conservation by initiating bear-specific research and conservation activities using camera traps, sign surveys, and evaluation of habitat and conservation threats.
The project also seeks to bring awareness and ignite bear monitoring and conservation through community outreach activities. Outputs from the project will be valuable for local-level conservation and development planning and for formulating a national bear conservation strategy and action plan for Nepal.
Sloth bear (Melursus ursinus) habitat is being degraded and fragmented in the Indian sub-continent. More than 85% of the Sloth bear population occurs in India, which is facing multiple threats such as habitat fragmentation, degradation and human-sloth bear conflict. While protected Sloth bear habitats are studied well, Sloth bear ranges in unprotected area have a lack of information and research. It is very important to understand the status and movement of Sloth bears in non-protected areas for conservation actions.
Previous studies also reveal that most of the Sloth bear attacks are prevailing in the non-protected areas and in the villages on the fringes of forests. The present research, carried out by WCB Lab, Department of Life Sciences, Hemchandracharya North Gujarat University, aims to study habitat quality, movement of Sloth bear and Human-Bear Conflicts in non-protected areas of Gujarat state of western India. It is felt that the findings of this research study would be lighten up status of Sloth bear and its habitat in Gujarat and would be also helpful in preparing conservation and management plans for such non-protected forest areas of the state, focusing on Sloth bear conservation and mitigating Human-Bear Conflicts.
Bears in Mind financially supports the research by WCB Lab in India since 2022.
