Rosettes in a matrix: Predicting spatial variation in density of a large felid in a forest-production mosaic 多用途景观中的“玫瑰花纹”：预测森林-生产镶嵌区大型猫科动物密度的空间变化

Abstract

Large carnivores are keystone for ecosystems and flagships for conservation efforts but face severe threats globally. Protected areas are vital for the conservation of these charismatic species along with a host of ecological processes. However, the extent and scope of protected areas for conservation of all threatened species is limited, especially in the global south. Considering larger landscapes that can be compatible with large carnivore conservation goals is an alternative approach to ensure their persistence. This study explores the potential of multi-use landscapes for the persistence of a globally threatened large felid, the Indian leopard (Panthera pardus fusca). This study investigated the spatial variability of leopard densities across a land-use gradient using spatially explicit capture-recapture framework in a tea-plantation-dominated forest-production landscape mosaic in the Duars region of northeastern India. While the density of leopards in this landscape was estimated to be 7.96 ± 1.56 (SE) per 100 km², significant (p = .048, t = 2.02, df=61) differences in estimates were observed between tea-plantations (11.53 ± 2.72 (SE) leopards per 100 km²) and the forested habitats (4.67 ± 2.07 (SE) per 100 km²). Densities between tea plantations and protected areas (a subset of the forested habitat) were found to be comparable (9.19 ± 4.55 (SE) per 100 km²). The study posits that conservation-compatible land use in landscapes shared with people can host a higher density of adaptable large felids like leopard than forested areas and that conservation planning needs to move beyond the dominant PA-centric paradigm. The study also reinforces the importance of multi-use landscapes for wildlife conservation, especially for an adaptable large felid.
