    Characterization of bone, ivory, Rhino horn and antler to deal wildlife offence cases.
    (Wildlife Institute of India, Dehradun, 2007) Singh, Rina Rani; Goyal, S.P.
    Species for this study were selected according to the endangered status of the species and since these products were difficult to identify mostly in processed form. Therefore, attempts were made to characterize bones of tiger (Panthera tigris) and leopard (Panthera pardus), greater one horned rhinoceros (rhinoceros unicornis) horn and antlers of chital (Axis axis), sambar (Cervus unicolor), swamp deer (Cervus duvauceli). Other than these species mentioned in synopsis, antlers of hog deer (Axis porcinus) and barking deer (Muntiacus muntajak) and ivory of Asian elephant (Elephas maximus) have also been characterized for comparison purposes. The present study is an effort to develop methods to characterize these items for conservation of the concern species and objectives of this study are as follows: 1. Determine morphological, crystallographic (XRD & XRF) and DNA characteristics of major bones of tiger and leopard, and 2. Determine morphological, crystallographic (XRD & XRF) and DNA characteristics of rhino horn and antler of chital, sambar and swamp deer species.

    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.

    Factors affecting habitat occupancy of tiger in the Terai Arc landscape, India
    (Wildlife Institute of India, Dehradun, 2009) Rajapandian, K.; Goyal, S.P.; Qureshi, Qamar
    The goal of this study, therefore, was to identify the factors affecting the distribution of tiger and assess the distribution of suitable habitat patches and the connectivity between these patches for successful dispersal in the Indian part of TAL. In the present study developed GIS probability models for tiger and its prey species and a spatially explicit individual-based dispersal model (SEIBM) for tiger in order to identify and assess the factors which are affecting the occupancy of tiger and subsequently predict potential suitable habitats and estimate the connectivity between the fragmented subpopulations in the Indian as well as between Indian and Nepal part of TAL. Data were collected on presence/absence of four wild ungulates (sambar Cervus unicolor, chital Axis axis, nilgai Boselaphus tragocamelus, and wild pig Sus scrofa), which are important prey species of tiger in two phases during the period between 2002 and 2006. The results of this study, in addition to contributing to the knowledge on factors affecting suitable habitat distribution and dispersal of tiger, have many implications for conservation of tiger in the Indian part of TAL. This study has also identified critical areas needed for management initiatives for functional unit of tiger conservation in the TAL.

    Status and ecology of leopard (Panthera pardus) in relation to prey abundance, land use patterns and conflict with human in Garhwal Himalaya.
    (Wildlife Institute of India, Dehradun, 2007) Chauhan, Devendra S.; Goyal, S.P.
    The problem of human-leopard conflict has recently been increased in the Indian Himalayan region due to change in land-use patterns. Leopard-human conflict as predation on human and livestock has been quite frequent in 16 districts of Uttarakhand state and Pauri Garhwal district is worst affected. Recent increase in such incidences has been reported from this region. The main goal of this research was to provide a base line information on status of leopard-human conflicts in Pauri Garhwal district and response of leopard in relation to prey abundance, land use patterns and human dimension in human dominated landscape. Present study was undertaken in Pauri Garhwal district of Uttarakhand to (i) determine distribution and current status of leopard in Pauri Garhwal (ii) to determine extent and severity of leopard-human conflict problems in relation to its ecological requirements, land use patterns and human life style. (iii) to study food habits in relation to prey abundance (wild and domestic) and habitat characteristics and (iv) to determine factor responsible for leopard-man conflict. A survey was carried from February 2000 to October 2001 in 15 administrative blocks of Pauri Garhwal district. Information was collected on distribution and extent and severity of leopard-human conflict.
