There is increasing evidence of the importance of multi-use landscapes for the conservation of large carnivores. However, when carnivore ranges overlap with high density of humans, there are often serious conservation challenges. This is especially true in countries like India where loss of peoples’ lives and property to large wildlife are not uncommon. The leopard (Panthera pardus) is a large felid that is widespread in India, often sharing landscapes with high human densities. In order to understand the ecology of leopards in a human use landscape and the nature of human-leopard interactions, we studied (i) the spatial and temporal distribution and the characteristics of leopard attacks on people, (ii) the spatial variability in the pattern of habitat use by the leopard, and (iii) the spatial relationship between attack locations and habitat use by leopards. The study site, located in northern West Bengal, India, is a densely populated mixed-use landscape of 630 km2, comprising of forests, tea plantations, agriculture fields, and human settlements. A total of 171 leopard attacks on humans were reported between January 2009 and March 2016, most of which occurred within the tea-gardens. None of the attacks was fatal. We found significant spatial clustering of locations of leopard attacks on humans. However, most of the attacks were restricted to certain tea estates and occurred mostly between January and May. Analysis of habitat use by leopards showed that the probability of use of areas with more ground vegetation cover was high while that of areas with high density of buildings was low. However, locations of leopard attacks on people did not coincide with areas that showed a higher probability of use by leopards. This indicates that an increased use of an area by leopards, by itself, does not necessarily imply an increase in attacks on people. The spatial and temporal clustering of attack locations allowed us to use this information to prioritize areas to focus mitigation activities in order reduce negative encounters between people and leopards in this landscape which has had a long history of conflict.

There is increasing evidence of large carnivores using human-use areas, but our understanding of their ecology in such landscapes is limited. The role of wild and domestic prey in sustaining populations of carnivores in human-use landscapes could be significant but is currently poorly documented. We studied the prey composition and diet selection of leopards (Panthera pardus) in a forest and tea-garden landscape in northeastern India where the population density is greater than 700 people per km 2 and average domestic animal density is 340 animals per km 2. Wild prey density in the landscape was 56 animals per km 2. Both wild and domestic prey were used by leopards in proportion to their availability with no selectivity toward either (2 ¼ 87.17, p ¼ .99, SE ¼ 0.001). Among wild prey, Rhesus macaque (Macaca mulatta) was found in high densities (24 animals per km 2) and was preyed by leopards more frequently that the proportional availability. High use of domestic prey by leopard, with 60% of the prey biomass comprising cattle and goats has the potential for negative impact on conservation support for the species. While on one hand, there is great scope for the persistence of large cats in dense human-use landscapes due to the availability of domestic prey, on the other hand, the study highlights the problems of livestock loss especially to poorer sections of the society which need to be reconciled for achieving long-term and sustainable conservation goals.
