Alpine pastures are a part of the agricultural use of land in the Alpine region but they are becoming overgrown. By comparing land use maps the dynamics of pasture overgrowth and other spatial processes in Belska Planina and Reber pasture were established. Digital ortophotos from the years 1995 and 2006 were analyzed by feature extraction with GIS tools. Changes at the level of the smallest surfaces, i.e. individual shrubs or cluster of trees, can be reliably identified with the methodology used without long-lasting visual land use delineation.
