Abstract
The characteristics of the state of Scots pine individual trees and tree stands in the areas with different levels of urbanization, including areas inside Yekaterinburg, city parks and forests outside of the city were studied. In city parks the tree stands’ state did not differ much from the state of the trees growing outside of the city, but inside the city timber volume decreased. Statistical analysis showed that this effect was due to summation of changes in stand density and trees size. Deterioration of the sanitary state of the trees due to environmental pollution and recreation accounted only for a small part of the changes in the volume stock. It was shown that mature tree stands in the city stayed resistant to the influence of negative environmental factors for a long time.
