Materials for the study of lichens of the natural recreational complex ‘‘Pine Forest of the Yagry Island’’ (Arkhangelsk Region)

The paper presents the first data on the diversity of lichens in the natural recreational complex “Pine Forest of the Yagry Island”. We have investigated pine and birch-pine forests growing on its territory and differing by the degree of anthropogenic load. The list includes 129 species and intraspecific taxa of lichens and taxonomically lichen-related fungi. Often-visited forest areas suffer from a significant anthropogenic pressure that has consequences as change in the species composition of lichens, various morphological damage to their thalli, and destruction of lichens by lichenophilic fungi. Sites situated far from the recreational facilities have been identified for the species normally found in old-growth poorly-disturbed forests. Samples of Naevia punctiformis and Scoliciosporum sarothamni are first listed for the Arkhangelsk Region. Bacidina assulata is listed for the second time for the Arkhangelsk Region.
