Abstract

The main concern of the article is to reveal influence of single pines of different age on meadow vegetation. It is shown that the pine can considerably transform environmental conditions and as a result change the structure of vegetative cover in its ecological field. Under the crones of pines the photophilous meadow species gradually disappear while forest and margin species tend to appear. Eventually in the central zone of an ecological field the formation of forest vegetation’s elements takes place. Three types of species reactions to the influence of the ecological field of the pine are distinguished, with negative reactions prevailing. The greatest influence on vegetative cover of meadow is exercised by old pines; successive vegetation changes cover of all zones of the ecological field.
