Land use, forest fragmentation and river dynamics in Dudhwa landscape and their conservation implications

Abstract

The present study aimed to assess land use, forest fragmentation and river dynamics in Dudhwa landscape and their effect on diversity, vegetation, and species of concern i.e. swamp deer ( ). Specific objectives addressed description of viii landscape spatial patterns, and evaluation of efficacy of high resolution satellite data in the development of spatial database; quantification of forest fragmentation, and assessment of structure and composition of forest vegetation; and understanding channel planform, changes in Sharda River, construction of Locational Probability Model of a stretch of Sharda River, and implications for conservation of endangered swamp deer and its prime habitat i.e. Jhadi in Kisanpur Wildlife Sanctuary. The study focused on the Dudhwa landscape which represents the part of The Sal ( ecosystem in the foothills of the Himalaya. In view of the multi-facet study objectives and vast area, it was imperative to adopt a holistic approach so as to have an insight on land use, forest fragmentation, and vegetation in the constituent areas of the landscape, and also on the river dynamics, a major disturbance factor influencing the floodplain and swamp deer. The field studies were carried out during 2005 and 2006. A combination of well tested field assessment methods and modern techniques Remote Sensing and GIS were employed in the present study.
