Quercus robur

Impact of environmental conditions on the vitality structure of the cenopopulations of the dominant tree tier in the forests of the southern part of the Volga Upland

The vitality structure of cenopulations of woody plants is formed under the influence of ecological, cenotic and anthropogenic influences. The study of the nature and degree of influence of the ecological parameters of the habitat will make it possible to predict the formation of the vitality structure of woody plants. The objects of study are individuals of the generative age state of three species of woody plants: Quercus robur, Tilia cordata, Acer platanoides. Environmental conditions of habitat were assessed by using range ecological scales.
