Abstract
The species diversity of lichens is represented by approximately 25 thousand species. Due to their wide distribution around the globe and the ability to survive in conditions unsuitable for all other types of flora, they are often called “vegetation pioneers”. Quite rare are the so-called cosmopolitan lichens, distributed throughout the globe. Determination of rare species, as well as species that can be classified as endangered, is a very urgent task for the possibility of preserving the species diversity of the lichen population in the State National Natural Park “Burabay”. The objective of this study was to study the distribution of rare lichen species in the territory of the State National Natural Park “Burabay”, located on the territory of the Akmola region of Kazakhstan, in the period from 2018 to 2022. In the course of the study, methods such as the method of route expeditions, the comparative morphological method, as well as some other special methods were used. The systematization of information on the species diversity of lichen flora made it possible to identify the most vulnerable species, and due to their vulnerability to environmental quality, in particular atmospheric air, as well as climate change, to develop measures to preserve the population. The collection of information to systematize the species composition of lichens was carried out during route expeditions. After the identification of taxa, the collected collection was subjected to the classification of occurrence according to the Drude scale, according to the results, schematic maps of the zones of lichen growth were left: out of eleven studied sites, three very rare species and four species of lichens in need of protection were identified in four. The information obtained is the basis for tracking changes in lichen flora and studying the correlation of these changes with the state of the environment.
