Abstract


Land-use /land-cover change has become a central component of current strategies in managing Resource. Study was carried out with an integrated approach using Remote Sensing and GIS techniques, monitoring land-cover change and understanding the dynamics of forest cover in the time interval of 25 years using Landsat TM of 1991 and 8OLI/TIRS of 2016 in Parsa National Park (PNP).   The aims of the study were to quantify   spatio - temporal pattern of forest   and to explore the proximate cause behind those processes. Supervised classification was used to prepare land use maps using the maximum likelihood algorithm. Overall changes in forest cover, as well as the fragmentation of dense forests within the Park were analyzed using landscape metrics.

During the 25-year study period, the forest area is increased by 9.14 Sq.km.Similarly, Lower vegetation is decreased by 21.733 Sq.km   .There is a rapid decrease in area of water body at the rate of 2.006% and rapid increase in expansion of River bank (Sand/Gravel) at the rate of 3.24%.The number of smaller patches in dense forest decreased rapidly.

Increase in Forest area is good practice management of Park and similarly two major and divergent trends are degradation and successional, were observed in the study. The degradation trend was indicated by the transformation of undisturbed forest to disturbed forest and other non-forest categories. These changes can be attributed to a number of causes, Succession, and uncoordinated policies of the different government agencies.
