THE INFLUENCE OF ANTHROPOGENIC FACTORS ON COENOPOPULATIONS AGRIMONIA EUPATORIA L. IN THE ANTHROPOGENIC DISTURBED ASSOCIATIONS OF NIZHEGORODSKY REGION

This work studies the influence of antropogehic factors to the coenopopulations Agrimonia eupatoria in anthropogenically disturbed oak forests of natural monument «Striginsky Bor» in Nizhny Novgorod. In disturbed oak forests are increasing the size of the Agrimonia eupatoria and the number of flowering shoots. Recommended measures to restore native oak. At present the forest phytocoenoses of the «Striginsky Bor» is feeling a big load of recreation. During this process the thickness and structure of his forest litter, whose role is very important, are changed. The forest litter supplies organic matters and regulates the microclimate. Alterations of the forest litter at the infringed phytocoenoses are manifesting more also in the correlations between vital forms of plants. The rhythmic and sizes of the main predominating species are changed. For example, ecological aerials oak forest on the territory of a relic in the Nizhny Novgorod of Nature-of the so-called «Stryginsky Bor» is change. As a result anthropological influence on forest the native populations of meadow and weed plants become abundant. Therefore, aiming the preservation of species, it is necessary to establish the control of a number of plant populations, the organization of forest reserves.
