This work examines the changes in the life state of Scots pine communities located in the immediate vicinity of the source of aerial anthropogenic emission with a clear decrease in its level in the time interval 2015-2018. It is shown that due to the physiological and ontogenetic characteristics of woody forms of plants, the response to changes in the level of pollution by the tree layer will be insignificant in a relatively narrow time interval (within the limit of statistical error). However, this response to the reduction of pollution will still manifest itself. Also, one of the reasons for such a slow response can be considered the accumulation of heavy metals in the organic horizons of the soil, where heavy metals form complex compounds (chylates) that are inactive for eluvial processes. The most probable way of development of these communities, while maintaining the current level of emission, will be a gradual increase in the life state of the tree layer to a certain value.
