    Development of Desert National Park as biosphere reserve
    (Wildlife Institute of India, Dehradun and BNHS, 2006) Kalra, M.; Rahmani, A.R.; Choudhury, B.C.; Qureshi, Q.
    The Biosphere Reserve Programme aims to conserve biological diversity, including the genetic diversity of cultivated crops, and domesticated and wild animals. It also aims to study the natural ecosystems and comparative studies on man-modified ecosystems. In order to conserve overall biological diversity of Earth, it would be desirable to constitute at least one or two biosphere reserves in each of the biogeographic provinces. More than 100 nations have already set apart 482 such reserves, since the UNESCO's Man and the Biosphere (MAB) programme was initiated in 1974. The hot desert in north-western region is a unique and the only habitat of its type in the Indian subcontinent. The Ministry of Environment and Forests constituted a working group in 1988 to draw a project document on the Thar Desert Biosphere Reserve (Anon. 1988). The objective of the Biosphere Reserve (BR) was oriented in such a way that BRs were wtits wherein the biological, socio-economic and cultural elements are integrated together. The main emphasis of this concept is the need for conserving ecosystem capable of being restored to natural condition. In this study we identified 16 unprotected areas in Bikaner, Jodhpur, Jaisalmer, Barmer, Nagur, Jalor and Sanchor districts with fairly large areas ranging from 5-7,091 km'. Each area supports mammals as well as several species of plants. These areas represent excellent animal-plant communities and traditional landuse practices, which together support a large number of microorganisms, small grasses and perennial herbs, which constitute the Thar ecosystem. The main emphasis of developing a Biosphere Reserve was given to Desert National Park (DNP). Vegetation as well as boundary mapping of DNP was done to visualize the land use/cover in and around it. All the villages in and around the Park were surveyed and mapped on GIS domain. This region includes the largest known populations of endangered species such as the Great Indian Bustard Ardeotis nigriceps, and the Chinkara Gazella bennetti and many lesser-known groups of plants and animals. The total area of propsed biosphere reserve is around 4,648 km' of which 76.36 km' will be as core zone, excluding four new areas, which are marked on the map, and 1,486 km2 transition zone. The existing area of the DNP is 3,162 km' which needs to be further extended upto 5 km from the park boundary. This extra (1,486 km') area will be use as a transition zone. In order to protect and enhance the biodiversity and cultural diversity of the Thar Desert, we also propose the concept of Greater Thar Desert (Marusthali) Biosphere Reserve, which should inelude the ON!>, Tal Chhaper, Diyatra and other biodiversity rich areas. We recommend that in the Greater Thar Desert (Marusthali) Biosphere Reserve, Community Conservation Areas (e.g. Guda-Vishnonian, Dhawa-Doli, Khichan etc.) and Conservation Reserves (e.g. Jakharda) should also be included

    A quantitative analysis of incidental capture of seaturtles and mortalities during commmercial shrimp trawling along the coastal waters of Orissa
    (Wildlife Institute of India, Dehradun, 2002) Gopi, G.V.; Pandav, Bivash; Choudhury, B.C.
    This study aimed to assess the efficiency of TED in reducing the mortality rate of sea turtles, with a view to lobby for the introduction and promotion of this approach in trawl nets in India. The aim was also to provide a realistic cost benefit analysis in terms of the economic loss to the fishing agencies on using the TED.
