Abstract

The article presents data on the distribution of the epiphytic lichen Lobaria scrobiculata (Scop.) DC. in the Arkhangelsk region. This species is widespread in the Russian Federation, but is quite rare and local. Neighboring areas listed this species in the regional Red Data Books (the Republic of Karelia, the Komi Republic, Nenets Autonomous Area). The first information about the vegetation of the species in the Arkhangelsk region was given in 2006. To date we identified three districts of habitat of L. scrobiculata and four districts were indicated in the published materials. The discovered habitats of species are found mainly in the northern part of the region in the moist coniferous forests with small-leaved trees. These forest sites are common in the “forest – bog” and “forest – lake” zones and floodplains of the forest rivers or creeks. L. scrobiculata grows on the bark of deciduous trees (goat willow, aspen, mountain ash, speckled alder and pubescent birch). The most frequently the lichen is observed on the trunks of goat willow and aspen. The lichen thallomes are located at a height of about 1 m, more rarely – at the bottom of a trunk, on snags and stumps. The limiting factors for the species are humidity and the violation of natural habitats. L. scrobiculata should be listed in the Red Data Book of the Arkhangelsk region as the species of the biological surveillance status.
