Changes in rotifer soil communities along a primary succession chronosequence was studied on brown coal post mining areas near Sokolov, NW part of the Czech Republic. The chronosequence of unreclaimed plots was 2, 11, 14, 20, 43 years old. The rotifers were extracted from soil samples using a modification of the Baermann funnel method with combined light and temperature gradients. In total, 34 taxa of soil rotifers were identified throughout the study. The most common species were Encentrum arvicola, Adineta vaga, A. steineri, Habrotrocha rosa, H. elegans, H. filum, Macrotrachela quadricornifera, M. nana. Rotifer abundance varied from 4±2.10³ to 516±488.10³ individuals m^-2. Species number per sample increased with age of the plot (r=0.45, P=0.003). The most important environmental variables which significantly affected rotifer community were wood cover, sodium concentration and age of the plot.
