The presence of bare surfaces is one of the main indicators for the degradation of natural ecosystems. The spread of bare surfaces and respectively the lack of vegetation cover is a serious threat to the sustainable development of complex environments such as mountains. The present study focuses on the spatial-temporal relationships of the bare surfaces with the local environment within the Bulgarian part of the small border mountain of Ograzhden. Based on temporal imageries from the Landsat 8 satellite, an analysis of the spatial distribution and tendencies in the development of bare surfaces has been made over a two-year period of time. Overall, the results of the research show a reduction in the total area of bare surfaces on the one hand and a slow environmental recovery on the other. Unfortunately, the positive changes are not ubiquitous but describe only certain areas of the territory of interest.
