Item Monitoring prey dynamics and diet flucuations of leopard (Panthera pardus) in Dachigam National Park, Srinagar, J&K(Wildlife Institute of India, Dehradun, 2016) Zaffar, Rais MirLeopard (Panthera pardus) is known for its ecological flexibility and wide distribution range. However, like other large carnivores, leopards are declining throughout their range due to habitat conversion, prey depletion, intense persecution and poaching for trade. In Kashmir valley leopard is at the top of the food chain and an apex predator that aids in regulating prey populations. Conservation and management planning of the leopards in Kashmir valley is impeded by the paucity of reliable empirical ecological information. There has been an increase in the human leopard conflict in the valley which, if left unnoticed, will worsen the conservation prospects of this threatened felid. Hence, this study was initiated to investigate the feeding ecology of leopard in Dachigam National Park and the human carnivore conflict around the park. The objectives of the study were estimating seasonal density and spatial distribution of prey species of leopard, studying the food habits and prey selectivity of leopard and quantifying the nature and extent of human-carnivore conflict around Dachigam National Park. The population of wild prey species was estimated in Dachigam National Park on seasonal basis using Distance sampling techniqueItem Conserving Natural Heritage Through Genetic Assessment : The Case of Snow Leopards in Ladakh(Wildlife Institute of India, Dehradun, 2021) Vishnuvardhan; Jhala, Y.V.; Srinivas, YellapuNatural world heritage sites are landscapes that sustain rare ecological processes, provide crucial habitats for the survival of many iconic species of significance and provide a wealth of ecosystem services. A part of India’s natural heritage lies m its youngest landscape, the Himalayas. This natural heritage is an asset in itself due to its immense intrinsic values. Snow leopard, an elusive inhabitant of the cold desert represents an important cultural and ecological symbol of the Central and south Asian mountain systems and acts as a flagship as well as an umbrella species. This study has been designed to assess the genetic status of this vulnerable species distributed across the union territory of Ladakh using non-invasive genetic methods. The study site comprised of four distinct regions, Hemis-Leh, Kargil, Changthang and Nubra. Putative snow leopard scat samples (N=391) were collected from the study area. DNA was extracted from all the samples and a 148 bp Mt-DNA region was amplified with a carnivore specific primer. Successfully amplified samples were sequenced for species identification. From the 95 snow leopard positive samples 56 individuals were identified using a panel of 10 microsatellites. Sex identification was also done by using AMELY gene and results showed male biased sex ratio in Ladakh. PIDsib value was 3.8x1 O’4 was indicative of sufficient power of the microsatellite panel to discriminate between siblings in a population of 10,000 snow leopards. This study provides a baseline for future comparisons since increased anthropogenic development projects may fragment this contiguous population. Genetic integrity and large gene pools are essential for long term viability of species especially in the advent of climate change and anthropogenic modifications. This study using genetic markers on the snow leopard exemplifies the use of this important tool for natural heritage management and conservationItem Tiger and leopard: Population ecology and resource portioning of sympatric carnivores in Kanha Tiger Reserve. M.P.(wildlife Institute of India, Dehradun, 2020) Kumar, Ujjwal; Jhala, Y.V.; Qureshi, QamarLarge investment in the form of protected areas, human resettlement, law enforcement-patrols and habitat management are made to conserve tigers and reap their benevolent umbrella role to secure India’s biodiversity. The objectives of present study are (i) the trend of tiger and leopard population (ii) demography of tigers and leopards and mechanism of their co existence. The study area was Kanha tiger reserve (area 2074 km2), a major stronghold for both species in central Indian landscape. Study investigate the estimated vital parameters of tiger demography through robust design based classical open population models in which population was open to demographic process. This study used both camera trap based mark-recapture and continuous monitoring known fate information to estimate reproductive parameters along with age specific survival and dispersal probability of tigers.Item Status and spatio-temporal ranging behavior of leopard (Panthera pardus) in Dachigam National Park, Srinagar, J&K.(Wildlife Institute of India, Dehradun, 2021) Noor, Athar; Habib, Bilal; Gopi, G.V.This study was initiated by Wildlife Institute of India, Dehradun with support funding from the Department of Science and Technology (DST), Government of India, in December 2010 to December 2013 to estimate leopard population and prey abundance, to study the leopard feeding habits and to determine the ranging behavior of leopards in Dachigam National Park. This thesis is an outcome of the main study and has three main objectives. The first objective being to determine the population status of leopards; second is to study the ranging behaviour and habitat use by leopards and lastly to model habitat suitability for leopards in Dachigam National Park. This study also provides basic information about co-occurrence of mammalian species in the community of the moist temperate forest of the Kashmir Himalaya, IndiaItem Habitat suitability evaluation for leopard (Panthera pardus) using remote sensing and GIS in and around Chitwan National Park, Nepal(wildlife Institute of India, 2011) Thapa, Tej Bahadur; Mathur, V.B.; Goyal, S.P.The leopard Panthera pardus is one of the large felid of Asia and Africa that is threatened by habitat loss and direct conflicts with humans. Owing to low population densities and cryptic habits leopard has remained little studied. This study evaluated landscape characteristics; determined distribution and relative abundance of leopards, analyzed diets of leopards and assess the extent, nature of human leopard conflicts and examined habitat use and preference in and around the Chitwan National Park and Buffer Zone (CNPBZ), Nepal. Methodologies used to accomplish these objectives included remote sensing, geographic information system (GIS), ecological field work (line transect sampling for prey, camera trapping for leopard and scat collection), social surveys and lab work for diet determination using micro histological technique. Abundance and density information forms the baseline for conservation planning. Camera-trap surveys were carried out during winter 2008/09 and 2010. This study provided much needed baseline information on habitat characteristics of CNPBZ, abundance of leopard and prey population, feeding ecology and prey selection by leopard, leopard- human conflicts and habitat use of leopards.Item Ecology of leopard (Panthera pardus) in Sariska Tiger Reserve, Rajasthan(Wildlife Institute of India, Dehradun, 2011) Mondal, Krishnendu; Shankar, K.; Qureshi, QamarThe present study estimated the prey availability and prey consumption, population and survival rate and the home ranges and resource selection of leopard in Sariska Tiger Reserve. The Sariska Tiger Reserve (STR) (N27o05’ to N27o45’ and E76o15’ to E76o35’) is situated in the Aravalli Hill Range and lies in the semi-arid part of Rajasthan for four consecutive years from 2007 to with these objectives: 1. To estimate the prey availability of leopard 2. To study the food habits and prey selection of leopard 3. To estimate the population of leopard and 4. To study the home range and habitat use of leopard. In the present study, food habits and prey selection of leopard were examined during the study period following scat analysis method and kill records. Radio-telemetry technique was followed to estimate the home range and habitat use of leopard as this technique is found to be the most updated and useful practice to gather information on home range, daily and seasonal movement pattern of big cats. The result of this study presented the abundance of prey species of leopard and their consumption by leopard in Sariska TR. The study also estimated the population and survival rate of leopard in Sariska TR. Home range and habitat use of leopard was estimated in the present study and a habitat suitability model for leopard was generated in and around Sariska TR.Item Prey selection and food habits of large carnivores: tiger (Panthera tigris), leopard (Panthera pardus) and dhole (Cuon alpinus) in Mudumalai Tiger Reserve, Tamil Nadu.(2010) Ramesh, T.; Sankar, K.; Qureshi, QamarA detailed long-term study on prey selection, food habits and population status of three sympatric large carnivores (tiger, leopard and dhole) was documented during the present study. To supplement the current basic information, the present study was conducted in Mudumalai Tiger Reserve, Tamil Nadu from January 2008 to April 2010. The objectives of the study include estimating density, group size and composition of prey species of sympatric carnivores, to study the food habits and prey selectivity of sympatric carnivores and to estimate the population of the sympatric carnivores. Prey selection and food habits of large carnivores were studied using two methods i.e by evaluating kills and analyzing scat. Data on population estimation of dhole was collected between January 2008 and December 2009. Five vehicle transect routes ranging from 15 to 23 km were monitored to record dhole sightings. Camera-trap and vehicle transect studies have showed that high densities of large carnivores in the study area of the Tiger Reserve.Item Study of leopard menace, food habits and habitat parameters in Mandi Distrcit, Himachal Pradesh.(Wildlife Institute of India, Dehradun, 2012) Kumar, Devender; Chauhan, N.P.S.This study deals status, distribution and relative abundance of leopard in relation to habitat characteristics of leopard. Estimation of status of leopard population and its distribution become more important in an area when a species is highly threatened due to continuous habitat degradation and loss of habitat due to the increasing human population. Many carnivore species are rare or elusive, and documenting their distribution is difficult. Habitat requirement is also one of the most important factors which influence the distribution and abundance of a species, therefore habitat evaluation is a vital step in the formulation of carnivore management in an area. Large carnivores need large areas of relatively wild habitat. The assessment of nature and extent of man leopard conflict in relation to land use pattern. Carnivores exert a profound influence on biological communities via predation and interspecific competition. Human-carnivore conflict is considered to be a major conservation and rural livelihood issue because many carnivore species have been heavily persecuted due to elevated conflict levels with communities. Present study documented about the enormity of the problem, problem areas and human casualties and livestock depredation with respect to places of occurrence, season, time and circumstances of attack. It would help plan mitigation of leopard problem, besides conservation and future scientific management of the species in Mandi district, Himachal PradeshItem Understanding aspects of demography and resource partitioning mechanisms of large felids among with abundance and spatial distribution of prey in Similipal Tiger Reserve, Odisha(Wildlife Institute of India, Dehradun, 2024) Rathore, Harshvardhan Singh; Pandav, Bivash; Jhala, Y.V.This study investigates the crucial aspect of coexistence for large predators like tigers and leopards sharing the same landscape and delves into the population dynamics of these animals by identifying the mechanisms of resource partitioning. By acting as a window into the inner workings of the ecosystem, the study reveals how tiger and leopard populations function alongside each other. Identifying the factors that influence their ability to share the resources successfully is vital for developing more effective conservation strategies. This knowledge ultimately contributes to ensuring the long-term survival of both tigers and leopards in this landscape. A precise assessment of several demographic parameters is necessary to make informed management decisions for their conservation within this unique habitat. These parameters include population density, sex structure, recruitment, and survival rates. With this background, the study comes with the following objectives. (1) To assess the abundance and spatial distribution of prey in STR.(2) To assess the various demographic parameters of large felids (tiger and leopard) in STR. (3) To determine the mechanisms of resource partitioning of the tiger and the leopard in STR. Similipal Tiger Reserve is located in the Mayurbhanj district of Odisha, between86˚06' and 86˚36' East longitude and 21˚31' and 22˚02' North latitude. The study was carried out over three years (2019–2021) across eight ranges in the core area of STR: Chahala, Nawana North, Nawana South, and Pithabata South Wildlife in the northern core, and UBK, Jenabil, Bhanjabasa, and National Park in the southern core.Item A Countryside carnivore: aspect of leopard ecology at Jawai, Rajasthan(Wildlife Institute of India, Dehradun, 2017) Sharma, Ravi Kumar; Qureshi, Qamar; Das, Abhijit1.Increasing human population and habitat fragmentation has impacted the large carnivore population across India. Leopard among pantherine is more tolerant to human disturbance and co-occur with humans in the wide variety of habitats. 2. Study was undertaken to understand status of leopard and factors responsible for its survival in human-dominated landscape. 3. Study was conducted in Jawai Dam Community Conservation Reserve from December 2016 to April 2017 in a semi-arid region of Pali, Rajasthan, India We examined villager's perception towards leopard by taking out the percentage of each response of respondents. Tolerance and religious view toward leopards was found significantly similar with each other, villagers has higher economic losses (livestock loss by leopards) than benefits (tourism activities) generated by hotel lobby. Villagers were examined to have minimal loss of human life and injuries by leopards, so it's easy to say about existence than co-existence or co-occurrence of both leopard and human in Proposed lawai Leopard Community Conservation Reserve.
