Abstract

The paper presents a taxonomic analysis of spruce forests coenoflora of the Arkhangelsk Region, conducted using the methods of comparative floristics. The author studied both natural spruce forests and those transformed by logging and human recreation. 410 geobotanical descriptions were given and dozens of routes were developed. The author revealed 311 species of vascular plants of 188 genera and 61 family. Top ten families include 165 species (55.0 % of the total number of native species) and 88 genera (49.2 % of the total number). The taxonomic spectrum of the coenoflora is dominated by Poaceae, Cyperaceae and Asteraceae families. Most of the species are of Carex, Salix and Equisetum genera. Adventive flora is presented by 11 species, or 3.5 % of the spruce forests coenoflora. The greatest number of adventive genera and species are of Asteraceae and Caryophyllaceae families. Among the coenoflora the author identified 11 species of vascular plants listed in the Red Book of the Arkhangelsk Region. The spruce forests coenoflora is of boreal type and bears no significant traces of anthropogenic transformation.
