Chinkara (Gazella bennettii), the Indian gazelle, is a widespread antelope in the arid and semi-arid regions of the Indian subcontinent; however, the species has been relatively unexplored to the south of its distribution range. In 2016, with indefinite evidence of chinkara presence in Yadahalli Reserved Forest, Karnataka, India, the Forest Department notified the area as a Wildlife Sanctuary (WLS). We conducted a study to explore their possible existence and population status at Yadahalli WLS using a novel approach. We laid 2 sq. km grid cells in the Yadahalli WLS and divided it into four replicated sub-grids using GPS. We walked the grid cells and recorded the chinkara midden and deployed camera traps for direct detection and individual identity. We recorded site covariates, i.e. tree density, tree diversity, basal area, food tree density, cattle dung, goat and sheep droppings and distance from the boundary, and detection covariates, i.e. trail length. We performed occupancy modelling based on midden recordings using PRESENCE ver. 5.3. Through the effort of 62 grids with four spatial replicates, the detection probability of chinkara was found to be 0.68 ± 0.03SE, and the estimated averaged occupancy was 0.51 ± 0.37SE. The present study reveals a potential population of ~85 individuals in the Yadahalli WLS, which is the known southernmost population of the species in India. This study establishes the use of novel methods for monitoring of chinkara populations which will help in the development of a conservation action plan for the species and its habitat.Keywords
