The lichens of forest rocky communities of mountain Olovgora (Arkhangelsk Region, Northwest Russia)

Abstract

The present study reports 223 species and three subspecies of lichens from forest rocky communities of mountain Olovgora, which is the highest point of the Vetreny Poyas ridge (Arkhangelsk Region, NW Russia). A total of 82 species are new for the mainland area of Arkhangelsk Region. The species Bryoria glabra has been reported for the first time for European Russia. Two recorded lichen species, Cladonia bellidiflora and Lobaria pulmonaria, are in the Red Data Book of Arkhangelsk Region. The occurrence of old-growth forests, high heterogeneity of conditions, presence of an altitudinal gradient and the proximity to the sea lead to the rich diversity of lichens in this area.

The lichens of forest rocky communities of the hill Muroigora (Arkhangelsk Region, Northwest Russia)

“…The climate of the study area is very close to the climate of the neighboring hill Olovgora described in our previous paper (Tarasova et al, 2015).…”

“…) (Tarasova et al, 2015). Both hills, Olovgora and Muroigora, are small, the total area of both together is less than one square kilometer but the lichen diversity of both areas is rather high (Olovgora -226 taxa, Muroigora -190 taxa, common -146 taxa).…”

“…The lichen diversity of the Arkhangelsk Region is still poorly known compared with the other regions of Russia (see Tarasova et al, 2015).…”

New records of lichens and allied fungi from Vodlozersky National Park within Arkhangelsk Region (NW Russia)

“…In the list 69 species are new for the mainland area of the Arkhangelsk Region. Altogether 514 lichens and allied fungi are known nowadays for the mainland area of the Arkhangelsk Region, taking into consideration data on 445 species known from the region before (Tarasova et al, 2015.…”
