SPECIES OF LICHENS RECOMMENDED FOR INCLUSION IN THE NEW EDITION OF THE RED DATA BOOK OF THE REPUBLIC OF DAGESTAN

During on the field work of 2009–2020 years were obtained data on diversity, distribution and oc-currence of lichens in the Republic of Dagestan including data on rare and endangered species. Based on them we recommend 24 species for inclusion in the new edition of the red data book of the Republic of Dagestan. Among them, 8 species are included in the red book of the Russian Fed-eration (Leptogium burnetiae, L. hildenbrandii, Letharia vulpina, Lobaria pulmonaria, Nephromopsis laureri, Ricasolia amplissima, Tornabea scutellifera, Usnea florida), 16 species are rare and vulnerable in the region (Anaptychia elbursiana, A. roemeri, Chaenotheca hispidula, Circinaria vagans, Coniocarpon cinnabarinum, Enterographa hutchinsiae, Flavoparmelia soredians, Hypotrachyna laevigata, Inoderma byssaceum, Lecanographa lyncea, Lobarina scrobiculata, Pannaria conoplea, Parmelina quercina, Sclerophora farinacea, Seirophora lacunosa, Usnea articulata). Most of the species (20) were proposed to be included with «Vulnerable» category, 2 species (Leptogium burnetiae, Nephromopsis laureri) with «Near Threatened» and 2 species (Tornabea scutellifera, Usnea florida) with «Least Concern». Most of the lichens recommended on protection are epiphytes and concentrated in forest communities on the Coastal lowland (Samur river Delta), in mountain broadleaved and mixed forests.
