Easy access and the abundance of valuable and large diversity forest products have led to higher population densities with opening new settlement areas via deforestation activities. In this study, interpretation of digital image classification resulted from multi-date Landsat-5 TM images recorded in time frame between 1992s and 2000s was evaluated to produce land cover maps for change detection analysis. The accuracy of the Landsat TM classification and errors inherent to the techniques used were assessed accordingly. The updated digital forest inventory plans, existing different scales topographic maps and aerial photographs was integrated into a GIS database with the generated classification results in order to elaborate a spatially explicit multi-date database on land use/cover change. This spatial model is used for identifying deforestation fronts and biodiversity conservation. As a result, several changes in the test site were observed, including increases in the areas extent of agriculture lands and urbanization with the corresponding decrease in Bartin Forest's wealth.
