The results of monitoring studies of forest vegetation in the vicinity of a gypsum mining enterprise in the Arkhangelsk region are presented. The study of the most important morphometric parameters and vitality of plants of all main tiers of forest communities, as well as extra-tier biota, which included epiphytic and epixylous mosses and lichens, was carried out.
