Transformation of ecological environment on coal dumps under the influence of Pinus sylvestris L. lead to formation of three-zone phytogenous fields. The undertree zone was characterized by smoothed temperature conditions, low illumination, accumulation of the forest floor and formation of plentiful undergrowth. The crown zone with high moisture content was characterized by the developed moss cover and low occurrence of undergrowth. The external zone served as a transitional space to background meadow communities and was characterized by the developed grassy cover, high abundance of species and group distribution of undergrowth of P. sylvestris L. Positive, adaptive and negative reactions of grassy plants to phytogenous fields of Scots pine were noted. The majority of species expressed negative reaction.
