Diagnostics of the condition of marginal territories by lichen-indication methods

Abstract

The author’s definition of marginal territories is based on the principle of their uniqueness, specificity, and isolation. Marginal territories mean closed border areas located on the edge of districts or isolated areas in the center under the influence of factors and released a higher diversity and number of species, characterized by isolation from the center, which are based on the isolation of life of the population of the district. The assessment of the quality of the environment for the comfort of living in marginal territories was carried out in comparison with the control areas related to the lands of localities and recreational territories. It is carried out on the basis of a comprehensive analysis of the habitat of groups of organisms sensitive to environmental degradation, belonging to the department of Lichens. The assessment of the condition of marginal territories was carried out by methods of determining the degree of lichen cover and the air pollution level parameter, the biotic index parameter, and the poleo-tolerance index in comparison with control territories related to the lands of settlements and recreational territories.
