Transformation of Forest Phytocenoses Near the Gypsum Mining Enterprise in the Arkhangelsk Region

Abstract

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. It was shown that the composition and structure of the forest stand, herbaceous-shrub, moss-lichen tiers, as well as extra-tier biota did not undergo noticeable changes. It was noted that on the majority of sample plots, which are located in close proximity to the quarry boundary, there was an increase in the number of undergrowth, changes in the height and vitality of undergrowth bushes.
