Abstract

The article presents the results of studies of the biodiversity of pyrogenically disturbed areas in the forest communities of the Ivano- Arakhleisky natural park, the identification of rare and specially protected plant species listed in the Red Book of the Trans-Baikal Territory and the Russian Federation. The lakes of the Ivano-Arakhlei system are located in the southeastern part of the Vitim plateau of the Osinovy and Yablonovy ridges. The territory of the park is characterized by the ecological value of natural areas, and is also a popular recreation area for citizens. Aquatic and terrestrial ecosystems are subject to anthropogenic impacts. Currently, digressive processes are dominant in the development of vegetation cover, leading to a simplification of the structure and a decrease in the species diversity of communities. Synanthropic plant species were recorded in the studied flora. The volume of ecosystem services provided directly depends on the biodiversity of the natural park. The general ecological condition of the study area is deteriorating due to an increase in anthropogenic pressure - forest fires, illegal logging, uncontrolled “wild” tourism, procurement of medicinal raw materials, and collection of beautiful flowering plants in bouquets.
