By changing habitat structure,their composition and configuration are changed and habitat loss and fragmentation occure.Acording to Patch-Matrix-Corridor Model, source patches,matrix and permeability of matrix for connectivity between patches are the strategic components of habitat that if they maintain, sustainability of habitat will be maintained. The aim of this study was monitorig the changes of strastegic components of protected areas as important habitats . For this purpose, Lisar Protected Area and the species of red deer is selected. In this study habitat suitability layer was considered as the foundation for defining the habitat patches and resistance surface was considred as the foundation of landscape connectivity and functional connectivity.With combining habitat suitability layer,resistanc surface,functional connectivity network and analysis of their temoral changes, the state of strategic elements of the landscape including the habitat patches, the permeability of the matrix , functional connctivity network and their impacts including habitat loss and fragmentation were analyze. The findings indicate that reduction of 36% of suitabe habitat (rating equal to or higher than 50) and reduction of 30-40% of landscape permeability reduced 35 percent of the habitat area. This study confirmed the fact that by measuring the resistance of land cover, potential of permeability of the landscap can be quantified and with intruducing landscape permeability index, the permeability of the landscape of Lisar protected area and Caspian red deer habitat was examined.
