Effect of village relocation on ground birds and small mammals in Sariska Tiger Reserve, Rajasthan, India

Abstract

1) Conservation related resettlement has been practised in India from 1960' s. However, studies related to the effect of village relocation on wildlife are limited. 2) Exploitation of natural resources by resident communities causes direct negative impact on native fauna and flora. These activities may include extraction of natural resources (fodder and fuel) or competition for the available resources by existing livestock with native fauna. Alterations in the vegetation structure can result in alteration of the bird community in these areas. 3) Galliformes is one such taxon that has been documented to be affected by human disturbance and grazing. These species are good indicators of habitat quality as they are solely dependent on the ground layer for food and cover. 4) There are 29 villages inside the Sariska Tiger Reserve and a relocation effort initiated as early as 1966 provides an excellent opportunity to study its effect on wild fauna and flora. 5) The study was carried out in four sites, with two sites where villages had been relocated 50 years (Slopka) and 10 years back (Bhagani); one site where village had been partially relocated (Sukola) and one where the village still existed The primary objective was to understand the influence of village relocation on Ggalliformes, small mammals and small carnivores. Additionally, vegetation structure at each village was also studied to understand influence of village relocation on natural vegetation.
