Study of Cladonia species growing in various areas of Burabai Park

Abstract

Studies of the lichen flora of the Burabai National Park were carried out in 2018-2022 in spring, summer and autumn by a route expedition. Depending on the purpose of the research work, the national park was divided into 11 sections.   By using the mapping scheme of lichen species obtained as a research object, it was found that out of 11 sites of the Cladoniaceae family, 18 species grow only on 7 sites.  Among them, Cladonia fimbriata, C.pyxidata, C. Cenotea, C. tenius, C. sulvatica, C. gracilis, C. alpestris were distinguished from other species by their distribution in several areas. In the study of the route, the frequency of occurrence of the lichen species, ecology, intrauterine form and features of reproduction were considered. Along with the determinants, a scanning electron microscope (JSM) was used to determine the types of cladonia.  Among the 18 species of cladonia belonging to the genus Cladonia, only a few individuals were found at the Zolotobor site among the research sites of the Cladonia coccifera. In this regard, the species of Coccifer cladonia was bred on the territory of the Burabai National Park as a species with a very low frequency of occurrence and in need of protection. The podecia of the epigeal Cladonia alpestris, which inhabited this area of the Burabai Park, spread over large territories. In this regard, it has been established that it grows in almost all areas of the National Garden in comparison with other species belonging to this genus. The free location of their substructural thallomas on the soil surface indicates that the species Cladonia alpestris is mainly due to the peculiarities of reproduction by vegetative pathways. In this regard, Cladonia alpestris was considered as the dominant species in comparison with other species of cladonia growing in the Burabai National Park.
