The climate change causes the increase in the air temperature, decrease in the quantity of precipitation, as well as the deterioration of the soil physical characteristics. The deterioration of the water-air soil characteristics will lead to the deterioration of the structure caused by the decrease of the nutrient content. The protective role of the vegetation will be reduced, the soil erodibility will increase, as well as the number of the wildfires, whereas the site conditions will deteriorate drastically. The global changes also affect the smaller regions, owning to which the monitoring of then is of a particular importance for the changes in the ecosystems. For this purpose we use the satellite photos of the high resolution, and by the use of GIS technology the method of the monitoring of the periodical changes in the ecosystems was developed. The collected data will enable the creation of the model which contain the dynamics of changes in the natural ecosystems. This paper analyses the hilly-mountain Rogozna area in Serbia. The classification based in EUNIS system of the site classification was applied. By the use of the satellite photos of the high resolution for Rogozna area the spacial distribution of the sites was defined. By the periodical recording of the characteristic areas in Serbia the spacial distribution of the ecosystems, as well as the changes in their composition and structure, will be monitored.
