Abstract
Abstract Quantitative ecological data needs to inform management of the endangered, endemic Sri Lankan leopard. Estimating habitat-specific leopard density and prey availability provides important baselines and improved understanding of the island-wide population. We used remote cameras in a spatially explicit capture-recapture framework to estimate leopard density (11.7 adult individuals/100 km2) and distance sampling to estimate prey density, within Horton Plains National Park. Sambar density was 178/km2 within the central grasslands, which represent a spatially anchored resource for sambar and in turn, a highly clumped, abundant resource for leopards. This study represents the first robust estimate of leopard density in Sri Lanka’s montane zone.
