Wind is one of the most damaging agents which the forest faces. In Sweden, wind and snow damage caused 75% of all mortality from 1965-71, and was equal to 15% of the total increment (Persson, 1975). Most of this mortality was in trees thrown over or broken by the wind. Table 1 shows that in Maine, mortality due to weather from 1960-70 was 5% of gross growth for softwood growing stock, and 7% of gross growth for softwood sawtimber (Ferguson and Kingsley, 1972). As the spruce budworm prompts more landowners to turn to partial cutting, wind damage is becoming an increasingly serious problem in Maine.
