This paper presents the analysis of the orographic, geological, pedological and vegetational characteristics of Grdelicka Gorge and Vranjska Basin areas, Serbia. This area is located at the altitudes ranging from 252 to 1.923 meters above the sea level. In the altitudinal zone ranging from 700 to 1000 meter above the sea level 26.75% of the area is located, in zone above 1000 meters above the sea level 24.97% of the area is located, in the zone ranging from 500 to 700 meters above the sea level 24.42% of the area is located, in the zone ranging from 300 to 500 meters above the sea level 23.29% of the area is located and in zone up to 300 above the sea level 0.57% of the area is located. The metamorphic rocks account for 41.1%, sedimentary rocks for 32.5%, and igneous rocks for 26.4% of the area. The acid brown soils account for 58.54%, eutric brown soils for 10.37%, vertisols for 8.57%, alluvial soils for 6.16%, etc. The oak and beech forests are the most common. Based on the model the changes in the forest ecosystems caused by the moderate increase of the air temperature (average increase of the temparature by 2.6-3.0 deg C) were determined.
