The suitability of the camera trap–retrap method was explored for identifying territories and studying the spatial distribution of leopards (Panthera pardus fusca) in the Jhalana Reserve Forest, Jaipur, India. Data from two years (November 2017 to November 2019, N = 23,208 trap-hours) were used to provide estimates of minimum home-range size and overlap. We conducted home-range analysis and estimation, using the minimum convex polygon (MCP) method with geographic information system (GIS) tools. We are aware of the limitations and advantages of camera trapping for long-term monitoring. However, the limitations of the research permit allowed only the use of camera traps to estimate the home ranges. A total of 25 leopards were identified (male = 8, female = 17). No territorial exclusivity was observed in either of the sexes. However, for seven females, we observed familial home-range overlaps wherein daughters established home ranges adjacent to or overlapping their natal areas. The median home range, as calculated from the MCP, was 305.9 ha for males and 170.3 ha for females. The median percentage overlap between males was 10.33%, while that between females was 3.97%. We concluded that camera trapping is an effective technique to map the territories of leopards, to document inter- and intraspecific behaviors, and to elucidate how familial relationships affect dispersal.

The ecology and predator–prey dynamics of large felids in the tropics have largely been studied in natural systems where wild ungulates constitute the majority of the prey base. However, in tropical countries where communities are primarily agrarian, the high density of domestic animals in human-dominated landscapes can be a potential prey source for large carnivores. We demonstrate almost complete dependence of the Vulnerable leopardPanthera pardus fuscain the Jhalana Reserve Forest in Jaipur, north-west India on domestic animals as prey. We analysed 132 leopard scats collected during the dry season of November 2017–April 2018. Domestic animals comprised the majority of the leopards' prey (89.5% frequency of occurrence): dogsCanis lupus familiaris(44%), catsFelis catus(13%), goatsCapra aegagrus hircus(16%) and cattleBos taurus(15%). Wild species, which occurred in the leopards' diet at a relatively low frequency, were rodents, the hareLepus nigricollis, small Indian civetViverricula indica, rhesus macaqueMacaca mulatta, northern plains grey langurSemnopithecus entellusand mongooseHerpestes edwardsii. Diet is also a function of availability of potential prey, but no data are available on the density of the leopard's wild prey species in Jhalana Reserve Forest. Nevertheless, our results suggest that abundance of domestic prey around Jhalana Reserve Forest sustains the c. 25 known leopards. We conclude that these leopards, by preying on feral dogs in an urban environment, could be considered as suppliers of a service to the human population amongst whom they thrive, although this potentially exposes the leopards to the canine distemper virus.

The intensity and frequency of human-animal conflicts has escalated in recent decades due to the exponential increase in the human population over the past century and the subsequent encroachment of human activities on wilderness areas. Jhalana Forest Reserve (JFR) presents the characteristics of island biogeography in the heart of Jaipur, which is a city of 3.1 million people. The leopard (Panthera pardus fusca) is the top predator in this newly declared sanctuary of 29 km². We surveyed people in the 18 villages that engulf this sanctuary. We questioned the villagers’ (n = 480) perceptions about conservation. As much as 93% (round figure) of the population has encountered leopards, and 83% were fully aware of its role in the ecosystem. In addition, 100% stressed the necessity of conservation to save the forests and 91% supported the efforts to a wall in the reserve in order to prevent human encroachment. Most of the population is Jains and Gujars, which are communities that believe in non-violence. We conclude that the villagers support conservation efforts. The authorities that manage JFR view the villagers favorably and, as stakeholders, are the basis for continued human-leopard coexistence.

Although Land Surface Temperatures (LSTs) are on the rise globally, the distribution of LSTs varies depending on the land cover type. Urban Heat Island and Urban Cool Island effects act differently, especially in semi-arid regions. Therefore, we identify demi-decadal, seasonal, and zonal differences in LSTs in a semi-arid region in the city of Jaipur, where zones include rural and urban areas that encircle the Jhalana Reserve Forest (JRF). After deriving LSTs from remotely sensed thermal bands of Landsat satellites’ Multi-spectral datasets, we found that there is a significant difference in LST (p < 0.01) among the zones. In addition, LSTs were found to be significantly lower in JRF compared to Urban and Rural areas in all seasons and all study years, which indicates the urban cooling effect due to the presence of the forest. Nevertheless, summer LSTs have warmed with a mean difference of 4.8 °C between 2000 and 2020. Therefore, our study supports the promotion of Urban Forests, especially in semi-arid zones, for inculcating LST regulation ecosystem services to enrich and enhance the standard of living of the human population.
