The peri-urban leopards of Kathmandu: assessing determinants of presence and predation on domestic animals A SHISH B ISTA,PRANAV C HANCHANI N ARESH S UBEDI and S IDDHARTHA B. BAJRACHARYA Abstract The conservation of large carnivores in human- Introduction dominated landscapes needs to be reconciled with the safety of humans and domestic animals. This is especially true for umans and large carnivores co-occur extensively where the leopard Panthera pardus, which occurs extensively in Hurban areas expand into or surround wildlife habitats agricultural landscapes and remnant forest tracts embedded (Zérah, ). Although large mammals do not always persist within peri-urban areas such as Kathmandu district in in areas with high anthropogenic pressure (Woodroffe, ; Nepal. We carried out interviews in households in this Ripple et al., ), they sometimes adapt to human-modified district to determine the extent of leopard habitat use and habitats including the edges of populous towns and farm- predation on domestic animals (dogs and goats) during lands, often sheltering, feeding and breeding in such areas October –April . We used multi-state occupancy (Gehrt, ; Beckmann & Lackey, ; Bateman & models, and estimated probabilities of leopard habitat use Fleming, ; Athreya et al., ; Odden et al., ). The conservation of large carnivores presents a conundrum (Ψ) and predation on domestic animals (Ψ) as a function of covariates, while accounting for imperfect detection. Our for wildlife managers and local administrators who are findings indicate that the rapidly urbanizing outskirts of tasked with protecting wildlife and ensuring the safety of Kathmandu city are used extensively by leopards.

There are many drivers for leopard igation plan that includes educational activities to raise occurrence in human-dominated landscapes, including habi- awareness, measures to address grievances of affected local tat fragmentation, wild prey depletion, attraction to domestic communities, interventions to prevent attacks on livestock, animals as easy prey and competitive displacement as a compensation programmes, and rapid response teams to result of inter- or intra-species interactions (Seidensticker, ensure human and animal welfare in conflict-prone areas. ; Odden et al., ; Ripple et al., ). Several studies Land-use planning in these peri-urban landscapes needs show that home ranges of leopards sometimes overlap to facilitate the safe sharing of space between people and partially or completely with human-use areas (e.g. Odden ’ leopards. et al., , ), which is facilitated by the species dietary plasticity.
