Item A study on sympatric carnivores (Tiger, leopard and wild dog) in Mudumalai Tiger Reserve, Tamilnadu, India : final report(Wildlife Institute of India, Dehradun, 2011) Sankar, K.A detailed long-term study on prey selection, food habits and population status of sympatric large carnivores (tiger, leopard and dhole) was documented in Mudumalai Tiger Reserve, Tamil Nadu from January 2008 to April 2010.The objectives of the study were to estimate density, group size and composition for prey species of sympatric carnivores, study the food habits and prey selectivity of sympatric carnivores and to estimate the population of sympatric carnivores. The study area was divided into 3 x 3 km2 grids for line transect sampling. In each grid, a line transect (1.5 to 3.13 km) was laid (n = 33) along which the prey density was estimated for two successive years (January 2008 to December 2010). Prey species availability was estimated using line transect method in an intensive study area of 180 km2 comprising dry thorn, deciduous and semi-evergreen forests. The total length of line transects was 41.3 km. Each line transect was walked thrice in the dry season (January to April) and wet season (May to December) yielding a total effort of 369.45 km. Vehicle transects were used to estimate group size and composition of prey species in the intensive study area. Five vehicle transect routes ranging from 15 to 23 km were monitored. Total transect length of 93.5 km was monitored twice a month resulting in a total effort of 3740 km.Item Ecology of leopard (Panthera pardus) in Sariska Tiger Reserve, Rajasthan : Executive summary(Wildlife Institute of India, Dehradun, 2013) Sankar, K.; Qureshi, Q.; Jhala, Y.V.; Mondal, K.; Gupta, S.; Chourasia, P.Item Ecology of leopard Panthera pardus in relation to prey abundance and land use pattern in Kashmir Valley(Wildlife Institute of India, Dehradun, 2014) Habib, Bilal; Gopi, G.V.; Noor, Athar; Mir, Zaffar RaisGlobally, leopard (Panthera pardus) is the most widely distributed and persecuted cat amongst large cat species. In India, it largely coexists with other feline species like the tiger (Panthera tigris) across much of its distribution range and with lion (Panthera leo) and clouded leopard (Neofelis nebulosa) in certain areas of its distribution range. Owing to its very high adaptability for surviving in varieties of habitats and opportunistic feeding behavior, it is often found to be at the center of the human-wildlife conflict. Retaliatory persecution, poaching, habitat loss and declining natural prey are some of the factors which lead to its population decline, despite being accorded protection through national and international legislations. In Kashmir Himalayas it is at the top of the food chain and an apex predator that aids in regulating prey populations. However, there has been an increase in the human-leopard conflicts in the valley which, if left unnoticed, will worsen the conservation prospects of this threatened felid. Hence, this long term study was initiated to address two major issues: 1. Conservation and management planning of the leopards in the valley is impeded by the paucity of reliable empirical ecological information and 2. Current threat levels will have to be assessed to understand and predict the impacts of anthropogenic pressure on leopards. The objectives of the study were to estimate leopard population and prey abundance, to study the leopard feeding habits and to determine the ranging behavior of leopards. Dachigam National Park was selected to undertake ecological studies on leopards. Only the lower Dachigam was chosen as an intensive study area as the upper reaches of Dachigam are mostly high alpine areas where leopards do not inhabit. In order to study prey abundance, line transect methodology was adopted. Transects (n = 13) were laid and monitored in the study area to obtain seasonal prey abundance. In order to estimate smaller prey (rodents) abundance, Sherman traps (n = 49) were used to estimate density. Feeding habits of the leopards were studied by collecting leopard scats (n = 714) which were later analysed using standard protocols. The population of leopard in the study area was estimated using camera traps (n = 12 pairs), deployed in 2x2 km grids in the study area to individually identify leopards with their unique coat patterns. The ranging pattern of leopards was studied by tracking the leopards (n = 3) fitted with Vectronics GPS collars. Amongst large prey, Himalayan grey langur and Hangul were sighted with enough records to be amenable to analysis in program DISTANCE version 6.0. In total 170 groups of langur comprising of 2679 individuals and 206 groups of hangul comprising of 829 individuals were sighted across different seasons in the study area. Overall density (±SE) of langur was estimated to be 16.32 ± 1.87 km ² and of hangul 5.11 ± 0.51 km-² in the study area. Langur density was highest (22.05 ± 5.12/km²) in winter season and lowest (9.35 ± 3.03/km²) in summer season whereas, Hangul density was found to be highest (9.51 ± 1.71/km²) in spring season and lowest (2.31 ± 0.51/km²) in summer season. In case of rodents, the density was found to be highest during summer season (2014 ± 830.71/km²) and lowest during winter season (1172.6 ± 442.74/km²). In case of dietary spectrum of leopard in Dachigam, small rodents contributed the maximum (48.05%) in terms of percent frequency of occurrence followed by langur (14.04%). Hangul contributed 2.05% while Himalayan serow contributed only 0.20% and rhesus macaque contributed the least (0.10%) to the diet of leopard. Minimum sample size required to study food habits of leopard varied from 66 to 86 scat samples in different seasons. Jacobs' index calculated from biomass availability and biomass consumption indicates that small rodents and langur were preferred in all the four seasons. Preference of hangul was slightly higher (-0.79) during winter season as compared to summer season (-0.90). A total of 396 trap nights resulted in a total of 14 leopard photographs with 3 individual leopards. Amongst the three individuals, 2 males and 1 female was photo-captured. Although, the Null (M ) model 0 was selected based on highest criterion score, we selected the Heterogeneity (M ) model because h leopards are territorial animals and it accounts for heterogeneous capture pobabilities between individuals. The density estimate produced by average home range radius (HHR) was 2.11 ± 1.06 2 individuals per 100 km which was found best as density of the leopard in the study area. The relative abundance index of the leopard in the sampling duration turned out to be 3.5 per 100 trap nights. The maximum home range (100% MCP) of the 2 female F74 was ~ 74 km which was recorded during summer season. The summer home range (100% MCP) of the male was 1.96 times larger than the female leopard. The least home range (~ 41.4 2 km ; 100% MCP) came up during the winter season. The increasing trend represented by the ranges (100% MCPs) of this female was winter < spring 2 2 (48.42 km ) < autumn (67.9 km ) < summer. The leopards showed large variation in daily distances moved during the lean season of summer. Daily displacements of the leopards were not normally distributed Kolmogorov-Smirnov Test) for the male: M73 (D = 0.119, df = 105, p = 0.001), female: F71 (D = 0.191, df = 105, p = 0.000) and female: F74 (D = 0.092, df = 105, p = 0.029). Daily displacement was longer for the male leopard (median displacement = 588 m) than the female leopard (median displacement = 367.44 m). The total distance travelled by the male leopard (398.71 km) was greater than the female leopards: F74 (374.16 km) and F71 (62.91 km). In case of female leopard F74, the median daily distance travelled was highest during the winter season (0.664 km) followed by autumn (0.528 km), spring (0.506 km) and summer (0.367 km) Findings of this study indicate that leopards are facing prey scarcity in the area, thus making them to rely upon suboptimal prey and occupy home ranges larger than other studies in the subcontinent. Leopards being opportunistic feeders have also started feeding on domestic prey in absence of sufficient wild prey, thereby elevating the human - leopard conflict in the region. Human - animal conflict being the major threat to large carnivores all across their distribution range is a big impediment in leopard conservation in he study area as well. 1.

Study movement pattern, home range size and social organization of leopards across different sitesItem Status of leopards in India 2018 : Summary report(Wildlife Institute of India, Dehradun, 2018) Jhala, Y.V.; Qureshi, Qamar; Yadav, S.P.Item Human wildlife conflict: Assessment of Socio-psychological perspectives and actual threat from Leopard in Motichur range, Rajaji Tiger Reserve(Wildlife Institute of India, Dehradun, 2019) Yadav. S.; Mohan, M.; Sandilaya, D.; Boro, P.; Sharma, A.; Sanatan, S.; Ramesh, K.As the proverbs go, “the deeper the roots, the greater the fruits” & “the devil is in the details”, for conservation management to be successful, one must look at multiple aspects and require comprehensive approach. Human-wildlife conflict is not a singular issue of management since it has wider implications and more so, in cases where species restoration in the form of conservation is involved, because social acceptance and better preparations are keys for success of such programs. In this report, information gathered from three different but linked studies carried out under the larger and long-term framework are synthesized, providing an overview of (1) socio-economic conditions and Quality of Life of people, (2) temporal landscape change and people perception on the conflict and (3) comparative status of leopard behavior in the conflict versus non-conflict zones. By studying “Quality of Life”, one can assess the impact of forest resources on the living conditions of people and vice versa. Chapter 1 shows the results of “QOL” study conducted within the villages falling under the 1 km buffer in the Eco-sensitive zone villages of Rajaji Tiger Reserve, Uttarakhand from January 2019 to June 2019. This study evaluates the socio-economic dimension of people and focused on demographic status, human dependency on utilization of forest resources and the role of people in management actions. The utilization of forest resources was found to be high in the three districts and there is hardly any participation of the people in the management inputs. The qualitative wellbeing assessment revealed that people are less satisfied with their living condition. The global environment change is increasingly forcing the already dwindled wildlife areas to be even more susceptible to disturbances. Localisation, shifting or disappearance of resources can severely impact wildlife and can even lead to local extinctions. There are many evidences to support this narrative. A study analysing the “changes in landscape” from 1995 to 2018 was also undertaken, which showed an increase in barrenness. Because “Human-Wildlife Conflict” explicitly revolves around the costs of sharing land with dangerous wild animals, it is important to understand the patterns of landscape change. While highlighting the landscape changes over a 20 years period, the second study also focused on the damages done by wild animals, the compensatory schemes, and most importantly the perception of people about wild animals. Though one can never truly eradicate human-wildlife conflict completely, any conflict is a situation of paramount importance to be solved, because any conservation effort does require the support of public at large, particularly the local people who share the space with wildlife. Any spike or change in trend of conflict requires further investigation not for the sole reason saving human fatalities but also for building better human relationships between wildlife managers and public. Since 2014, Motichur range of Rajaji Tiger Reserve has experienced 31 attacks on humans by the resident leopard (Panthera pardus) population. It resulted in 19 human deaths and grievous injuries to 12 people. The epicenter of the conflict is the space surrounding national highway 58, connecting the cities of Rishikesh and Haridwar. Rajaji forest department has been deploying camera traps in the conflict space to reckon the leopard movement patterns and to circle out any suspect animals responsible for the conflict. We intensified the camera trap study focusing on entire Motichur range (excluding the conflict locations) from November 2018 to February 2019. In addition, we visited each conflict site with the forest department officials, and collected information on various attributes related to the site. We found an extremely high leopard count for the winters i.e. 47, with a very high density of 45 animals per 100 square kilometers. We listed down the most suspected leopards involved in conflict based on 3-point criteria. The results of our work will increase our understanding of the adaptability of leopards. The results also reiterate the imperative to shift from a PA centric to a landscape level conservation approach, analyzing the source and drivers of conflicts, including the carrying capacity analysis. There is also an urgent need to include engage communities more closely and develop a short-term and long-term conservation programs.
