ASSESSMENT OF THE CONDITION OF PINE PLANTATIONS ALONG URBAN ROADS OF VORONEZH CITY
We have studied the state of pine phytocenoses in the city of Voronezh, along highways with different traffic intensities. A general degradation in the state of forest stands, a decrease in productivity, damage to radial growth were established. At a distance of 25-30 m from the highways, there is a decrease in the density and stock of forest stands at both sites, due to a decrease in lateral illumination, while the intensity of pollution decreases slightly. At a distance of 185-195 m from the highway at both sites, the height and growing stock reach their maximum values. Density and average diameter vary in different directions due to the presence of a concomitant recreational impact at the ―Prigorodnoye lesnichestvo‖ facility.
