An ecological assessment of forest spatial heterogeneity species diversity and grassland burning practices in the terai conservation area.

Abstract

The present study formed a part of the major collaborative project entitled "Management of Forests for Biological Diversity and Forest Productivity - A New Perspective", jointly implemented by the Wildlife Institute of India and the US Forest Service. The project aimed to address the primary requirement of forests of sustaining biodiversity. It is being realized that the traditional forest management approach had to undergo a major shift in emphasis and strategies. The project expected to demonstrate the integration of science and management in a planning process that establishes the complimentary roles of wildlife protected areas and the large surrounding landscape of managed forests in maintaining forest based biological diversity. The project was field based at four Conservation Areas (CAs) that covered large landscapes of forested and non-forested matrix areas representing a variety of biogeographic patterns, forestry practices, ethnic human societies and their forest based culture, economies and tradition, and the range of administrative realities. Each of the CAs included select protected areas (PAs) - National Parks or Wildlife Sanctuaries; Managed Forests (MFs) and the intervening matrix of the Government, community or private lands so as to constitute a larger delineated landscape. The present study specifically focussed on the Terai Conservation Area (TCA), one of the four CAs. The TCA covering 7,896.6 sq km constitutes a spatial heterogeneous landscape of Pas including Dudwa Natioal Park (DNP) and Kishanpur Wildlife Sanctuary (KWLS); and Managed Forests (MFs) of North Kheri and South Kheri Forest Divisions (NKFD and SKFD) within a matrix of private agricultural lands. the present study focused on the landscape spatial patterns, their influence on species diversity and also the effect of various grassland burning practices in TCA. In order to achieve this, the following objectives were set forth for the present study: a.To assess, characterize and map the current land use and landscape patterns. b.To identify, classify and describe vegetation communities, assess their extent and geographic distribution in the landscape. c.To assess the influence of landscape spatial patterns on habitat and species of particular management interest. d.To assess grassland burning practices vis-a-vis plant diversity, productivity, ungulate use and make appropriate recommendations for the management..
