The main cause of the global threat to large carnivore populations living in high-altitude areas is human pressure. Himalayan brown bear ( Ursus arctos isabellinus , hereafter bear) listed as a critically endangered species, and it dominates higher altitudes North Western landscapes. Here, we used species distribution modelling landscape connectivity find bears’ suitable habitats corridors Deosai National Park (DNP) surrounding areas. Species models detected bear’s habitat 1,125 km 2 which ca. 73% was covered by DNP. most crucial predictors determining were elevation—particularly if between 3,500 4,500 meters above sea level—as well distance from rivers, cattle, DNP borders. We discovered robust among presence points core study area, particularly within boundaries, using electrical circuit theory models. Landscape values indeed low some outside close confines. Based on our findings, imperative protect that allow bears migrate patches, beyond park’s improve conservation.

Abstract Habitat fragmentation and loss are considered primary threats to common leopards ( Panthera pardus ) across their geographical range. We investigated anthropogenic environmental factors influencing the habitat suitability of in northern Pakistan using an ensemble model direct indirect leopard signs during 2014–2022. Using location data from 206 sightings model's performance was good (true skill statistic, TSS = 0.52). highest forest cover negatively related density settlements roads. peaked at intermediate elevations (about 1000–2000 m). Based on model, we estimated 4543 km 2 Pakistan, which 3144 (69%) occurred six contiguous patches least 58 (range 65–951 ), minimum size support one female leopard. There patch within a protected area, overall, 36% total areas were as suitable. Our findings suggest that current network does not adequately represent suitable for leopards; increasing expanding area could improve suitability.
