Large carnivores utilize human areas, resulting in frequent conflict with humans. We aimed to identify the factors affecting the habitat use of leopards and sloth bears in human-dominated areas of the proposed Jawai Leopard Community Conservation Reserve, Rajasthan, western India. Within the 1 km(2) grid framework, the presence of species was recorded (84 events - leopards and 71- sloth bears) and modeled using the maximum entropy algorithm concerning terrain and land-use pattern-related covariates. Also, we modeled the potential movement areas using the least-cost pathway approach. Outcomes informed that suitable habitats for leopards (126.1 km(2); 40.8% of study area) were more widely distributed than sloth bears (103.7 km(2); 33.5%). Models suggested that elevated-rugged hillocks were positively related to both species' habitat use, followed by scrub and water resources. Leopards showed more adaptability towards human set-tlements than sloth bears. Thirty potential movement pathways (between 15 core habitats) for leopards and 19 for sloth bears (between 11 core habitat nodes) were identified; out of these, 45% and 48% of pathways for leopards and sloth bears, respectively, are facing threats by the movement barriers such as railway tracks and human settlements. Conserving highly and moderately centralized pathways can be a better approach for sustainable landscape conservation in parallel.
