The Dynamics of the Scots Pine Forests Condition under Changing Emission Loads
T. A. MIKHAILOVA AND N. S. BEREZHNAYA
Abstract
The dynamics of pine (Pinus sylvestris L.) stands polluted by fluorine-containing emissions was being studied for some decades - from the moment when emissions appeared till at present. Condition of the pine stands was estimated by contents of the pollutants in the needle, and a number of physiological and morphometrical parameters of the trees. Some stages in the forest decline under fluorine-containing emissions were revealed. On the base of the data obtained and the regressive analysis, situations were forecasted according to the following scenarios: a) emission load will not be changed, b) emission load will be increased, c) emission load will be decreased, d) emission load will be eliminated.
