Species composition of lichens in the zone of impact of a coal mining enterprise

This article presents a multi-aspect analysis of lichens growing in the impact zone of a coal mining enterprise located in the Altai District of the Republic of Khakassia. The study was conducted every month from May to October for four years together with the staff of the Department of Biology. The collection of material was carried out according to the generally accepted methodology in the vicinity of the Bolshoe and Stolbovoe lakes located on the territory of the enterprise. The length of the study area was 8 km. 41 species of lichens from 13 families and 24 genera have been found in the vicinity of Bolshoe and Stolbovoe lakes, settling mainly on rocks. Lichen samples were also collected on soil, trees, shrubs and concrete slabs. The familial and generic spectra of lichens characterize this research area as arid and are noted for lichenoflora of the temperate Holarctic. The life forms and ecological groups of the studied lichens on the territory of the Bolshoe and Stolbovoe lakes are typical for steppe.
