    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.
