Abstract
Correlations between the structure of phytocenoses representing different stages of the process of forest formation in the Polar Urals mountains and moistening of ecotopes, as well as between the lower layers and forest stand are considered. Current density of trees and undergrowth is not exhaustive of the ecotope capacity, and therefore open woodland can be transformed into closed forest. Perspectives of such a transformation within a certain plot may be assessed by percentage of mesophilic and relatively thermophilous (hypoarctic + boreal) species in the herb-dwarf shrub layer.
