    Ecology of the Asiatic Lion Panthera leo persica.
    (Wildlife Institute of India, Dehradun, 1993) Chellam, Ravi; Johnsingh, A.J.T.
    The major objectives of my study were to assess the predation ecology, habitat use and the ranging patterns of the lions in the Gir forest. The ultimate and long term goal of this research effort was to examine the feasibility of a translocation effort in an attempt to establish a free ranging population of lions away from the Gir forest. The ecological data generated a free ranging population of lions away from the Gir forest. The ecological data generated would enable the assessment of prospective translocation sites and insights gained about lion behavoiur. This study was designed to have an extensive scope to generate base line data for planning and management of gir forest and the lions.

    Ecology and Management of Lion and ungulate habitats in Gir.
    (Wildlife Institute of India, Dehradun, 1995) Sharma, Diwakar; Johnsingh, A.J.T.
    The Gir is the only refuge of the Asiatic lion (Panthera leo persica) in its range. This implies that long term conservation of the Asiatic lion will remain an overirding management objective. A study on the impacts of management practices on lion and ungulate habitat was conducted in Gir Protected Area (PA) from June 1991 to July 1994. The Gir . PA includes Gir Wildlife Sanctuary and National Park. It is situated between 200 55' to 21 0 20 'N and 700 25' to 71 0 15' E in the Southern part of Kathiawar peninsula in western Gujarat. Gir PA (hereafter Gir) is located about 60km South of Junagadh. The area which was .3,107 sq km iIi 1877 (Joshi 1976) has been presently reduced to 1,412 sq km, o~ which about 259 sq Ian is national nark. Gir is the last refuge of the wild Asiatic lions (Panthera leo persica) and long term conservation of the Asiatic lion is an overriding management objective of Gir. In order to improve habitat conditions in Gir, the park authorities, over the last 20-25 years have made some management interventions such as relocation of some maldharis (local graziers), reduction in livestock grazing (specially migrant livestock during the rainy season) and fire control. These measures have led to vegetational recovery and increase in wild ungulate and lion populations. Understanding this vegetational recovery was thought to be crucial to determine the extent of management intervention required. It also needed to be determined if the trend (especially in the western Gir) was toward a higher woody proportion both at shrub and tree levels, and whether this in long term would adversely affect ' the distribution and abundance of ungulates, and therefore, group hunting by the lions, their pride size and territoriality.

    Habitat Selection by Indian Peafowl (Pavo cristatus linn) in Gir forest, India
    (Wildlife Institute of India, Dehradun, 1993) Trivedi, Pranav; Johnsingh, A.J.T.
    A study on habitat selection by Indian peafowl (Pavo cristatus) was carried out in Gir National Park and Sanctuary over a period of five months. Open width line transects were laid at three study sites in West, Central and East Gir respectively to obtained information on availabili ty and use of habitats. Three hundred and thirty sightings were obtained in 90 transect walks (totalling to ca 113 km), of which two hundred and fifty occurred in West, and forty each in Central and East Gir. As sampling intensity was the highest in Sasan (West Gir), much of the analyses is based on the data collected here. Peafowl distribution was found to be clumped, with the degree and site of clumping being affected by water and food availability
