    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.

    A study on vegetation ecology in Pench Tiger Reserve, Madhya Pradesh with reference to gaur (Bos gaurus) using Remote Sensing and GIS techniques.
    (Wildlife Institute of India, Dehradun, 2007) Areendran, G.; Sankar, K.
    A study on vegetation ecology with reference to Gaur (Bos gaurus) using remote sensing and Geographic Information System (GIS) in Pench Tiger Reserve (PTR) Madhya Pradesh was conducted from February 1996 to September 2000. The Tiger Reserve is located between 77° 55' W to 79° 35' E & 21° 08' S to 22° 00' N and lies in the southwestern region of the state of Madhya Pradesh. The Tiger Reserve comprises of the Sanctuary and the National Park of the same name, and buffer zone covering an area of 757.85 sq. km. The PTR offers a unique opportunity for research into the aspects of both the ecology and the management of gaur populations and their habitats. This is due to, both, the diverse pattern of habitat, as a result of rich floral composition and varied topology, and gaur populations that can readily be seen almost throughout the year. In Madhya Pradesh alone, the gaur population is found in 10 districts and they are geographically isolated from one another. The main objectives of the study were: 1)To study vegetation communities, composition, species distribution, abundance and richness in Pench Tiger Reserve, Madhya Pradesh. 2)To map vegetation types and quantify landscape characteristics in PTR, 3)To evaluate the available habitat and predict distribution areas of Gaur in PTR, Madhya Pradesh. model the habitat suitability and predict distribution of Gaur in Pench National Park based on Ecological niche factor analysis (ENFA) using Biomapper software Different variables (Aspect, Cover change, Drainage, Elevation, Food dentity, Ground cover, Slope, Vegetation type, Vegetation index ) were used in the model to predict the suitable habitat and distribution of Gaur

    Evaluation of impact of landscape changes on large mammal habitats in Pench Tiger Reserve, Madhya Pradesh, India
    (Wildlife Institute of India, Dehradun, 2012) Basu, Santanu; Sankar, K.
    A study on the vegetation and wildlife habitats was conducted in the Rajaji-Corbett National Parks and adjoining areas using remote sensing, geographical information system (GIS) and conventional field sampling techniques. Steady increase in anthropogenic pressures in this area has led to degradation and fragmentation of wildlife habitats and related environmental problems. While the two national parks have received attention due to their legal status, the surrounding areas such as the vital corridor connecting the two parks have been largely overlooked. This connecting forest faces dual threat from the surrounding villagers as well as the migratory pastoral communities viz., Gujjars and Bhotias. The literature review reveals that vegetation ecologists have conducted a few studies within Rajaji and Corbett National Parks. Most of the studies pertain to documentation and description of plant species, analysis of community structures, analysis of the problems of sal regeneration and habitat ecology of selected species in isolated areas. However, no effort had so far been made to analyse the overall terrain and landscape features in relation to vegetation structure in the area, which is essential for characterizing the wildlife habitat. Detailed maps depicting the vegetation types, terrain categories and habitat suitability for major ungulates were not available for the area. Similarly, no literature was available on the patterns of plant species diversity in relation to the habitat conditions. Therefore the present study was undertaken in this area. The specific objectives of the study area were to: 1) Spatially analyse the vegetation types, terrain categories and prepare maps for the same using remote sensing, 2) Study the structure and composition of various vegetation types in the corridor area.3) Study the patterns of plant species diversity and other related parameters. 4) Analyse habitat characteristics for major ungulates using Remote Sensing and GIS. The extensive study area was analysed through maps prepared using remote sensing techniques. This area covers about 10,766.7 km 2 and lies between 2900' to 30031' Nand 77015' to 80016' E. It includes the following national parks: a) Rajaji National park (820 km2 29052' to 30015' N and 77055' to 78019' E), and b) Corbett Tiger reserve (1320 km2, including 520 km2 of core area, 29025' to 29040' Nand 7805' to 7905' E).

    Application of Geographic Information System(GIS) and Remote Sensing in assessing habitat, resource availability and its management in Tadoba-Andhari Tiger Reserve.
    (Wildlife Institute of India, Dehradun, 1999) Dubey, Yogesh; Mathur, V.B.
    The present study attempts to determine the distribution and abundance pattern of ungulate species in Tadoba Andhari Tiger Reserve and to assist in the development of a computerised wildlife database on spatial as well as non spatial attributes, which could be used for conservation monitoring and evaluation as well as to help in resource management planning, With the increasing pressure on forests it has become important to focus the research effort which could eventually lead to a better management of our PAs.
