英文摘要	Wolves play a crucial role in shaping ecological communities as an apex predator in the thy-open forests of semi-arid landscapes in India. Large scale habitat loss pertaining to human expansion and retaliatory killing by human caused severe decline in the wolf population across its range. The estimated wolf population size is close to 2000-3000 individuals in India; however, these estimates were decades old and the present status of the wolf in the semi-arid landscape is largely unknown. We assessed the distribution of wolves in Kailadevi Wildlife Sanctuary, Rajasthan using occupancy models and identified important factors associated with habitat-use by wolves. Occupancy modelling shifts the focus from individual animal to a site, while accounting for detection probability. To assess the habitat-use we used sign-based surveys that rely on data collected from adjacent sampling sites (replicates). The habitat-use was assessed across 672.82 km(2) surveying 48 grid cells, each measuring 14.44 km(2). Estimated habitat-use Psi (SD) was found to be 0.82 (0.14). Our findings suggested that availability of agriculture land had the significant positive influence on the habitat-use of wolves. Other factors such as availability of water, scrubland, and wild prey (nilgai and chinkara) also had a positive effect on the habitat use of wolves, but it was not significant. Forest cover has a negative influence on the habitat use of wolves. This study is the first rigorous assessment of the Indian grey wolf habitat-use at the level of wildlife reserve with potential conservation value that can be applied to other areas in India.
