The paper presents the results of the researches of the ecological indexes of the forest communities in southwestern Serbia. The ecological indexes for the humidity, chemical soil reaction, nutrients, light and temperature were determined. The following forests were researched, on the total of 93 samples: the sessile oak and Turkey oak forests, silver birch forests, European poplar and silver beech forests, beech forests, beech and fir forests, black alder forests, grey alder forests, grey willow forests, Austrian pine forests, Scots pine forests, Balkan sessile oak forests, beech-fir and spruce forests, mountain maple and spruce forests, and spruce forests. The studied sites are located at the altitudes ranging from 1,010 meters to 1,500 meters above sea level. The communities were registered in the dystric ranker, dystric cambisol, eutric ranker, eutric cambisol, fluvisol, gley, colluvium, limestone cernozem, luvisol, pseudogley, and brown limestone soil. The ecological indexes for the humidity ranged from 2.13 to 3.47, for the chemical soil reaction from 2.23 to 3.45, for the nutrients from 2.11 to 2.99, for the light from 2.11 to 3.39, and for the temperatures from 2.96 to 3.42.
