The prevailing species were Colpoda stein Colpoda maupasi and Colpoda aspera for all types of soils of the study area. The dependence between the number of ciliates soil moisture, and acid-base indicator. The main anthropogenic factors affecting the value of indicators are exploration to mechanical disruption and chemical contamination of the soil cover.These studies can be the basis as baseline information when conducting biomonitoring. The same materials can be used in bioindication for assessment of the anthropogenic impacts on the environment.
