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.
