Abstract
The anаlyses of biotic diversity using pictographs show the difference in deviation of the diversity under long-term period of deforestation and under short-term violation of forest habitats. The biomass of small mammals was similar in all forest habitats; it was higher at the meadow and dropped in the young (9 years) forest at the former field. Though the numbers of species as well as the diversity of local communities of small mammals vary, the biomass of residents was similar in forest habitats. Nonresident population contributes to general biomass the more the greater habitat is deteriorated. The relevant sustainability of general biomass is regarded in terms of biocenotic compensation. Biocenosis is regarded as a system having an inclination to "autonomic" functioning.
