    Ecological investigation of human-elephant conflicts in south-west Bengal.
    (Wildlife Institute of India, Dehradun, 2006) Singh, Anil Kumar; Chowdhury, Sushant
    Human-elephant conflicts- perspective in Asia and Africa: a review” contains an account of human elephant conflicts and its negative interactions both for elephant and humans in Asia and Africa. This provides an illustrative account of sources of human elephant conflicts and different forms of negative interactions resulting damage to agriculture and plantations, damage to property, human kill and injuries, impact on ecosystems, killing of elephants and diseases transmissions. The modes of conflict management through ecological approach, habitat improvement, alternate crop strategies, deterrent, repellents and aversion, physical and pulsating barriers, acoustic deterrents and compensatory measures as adopted in Africa and Asia on both the genus of elephants are discussed and reviewed.

    Ecology, demography, conservation and management of Greater One Horned Rhinoceros (Rhinoceros unicornis) in Chitwan National Park, Nepal.
    (Wildlife Institute of India, Dehradun, 2015) Adhikari, Khagendra; Chowdhury, Sushant
    From this study, we can get the information about population status, demographic parameters, food and feeding ecology, habitat utilization, habitat preference, home range and movement and dispersal pattern of rhinoceros. This study will be useful in making plans for the conservation and management of this vulnerable species. Objectives of this study are as follows : to estimate the population status and analyze the demographic profiles (age structure, sex ratio, birth rate, death rate etc.), to study the feeding ecology, to find out the habitat availability and to study the habitat utilization, home range, movement and dispersal pattern.

    Spatio-temporal abundance and resource selection of Indian wild ass (Equus hemionus khur) and nilgai (Boselaphus tragocamelus) with special reference to crop-depredation and people’s attitude in Little Rann of Kachchh, Gujarat.
    (Wildlife Institute of India, Dehradun, 2022) Barman, Bidyut Bikas; Chowdhury, Sushant; Shah, Nita; Qureshi, Qamar
    The harsh climatic condition and unpredictable resource availability like water is the nature of arid and semi-arid ecosystems which is epitomised by the Little Rann of Kachchh (LRK) landscape. Indian wild ass (Equus hemionus khur), a sub-species of Asiatic wild ass, idiosyncratically represent the LRK landscape which has been holding its last remaining population after it had become extinct from its previous home ranges. In my study, I emphasised on estimating population density of Khur and Nilgai, which is the other sympatric ungulate in the landscape using widely accepted and robust scientific method. Also, intensive monitoring was very challenging due to logistic limitations and large study area. I had designed my study focusing on the southern fringe of the sanctuary as the intensive study area (ISA) and conducted temporal replicates to see the density of Khur in both summer and winter. In this study, I have developed habitat suitability map of Khur and Nilgai. Apart from the resource rich areas, it is imperative to see how the habitat model suggesting potential sites based on selected environmental variables which actually shaping their distribution in the landscape. This study identified northern part of the sanctuary connected by a bottle neck with the Greater Rann of Kachchh as a potential site which demands management intervention at large scale involving other line departments ensuring a safe corridor between LRK and GRK for Khur and Nilgai. I have studied the perception and attitude of local farmers in the southern fringe towards crop-depredation. Although, with growing rural population and increase in intensive farming, the overall attitude of farmers were observed to be mixed with both positive and negative attitude reflected in their perspective towards crop-depredation by Khur
