Wind is one of the most damaging agents which the forest faces. In Sweden, wind and snow damage caused 75% of all mortality from 1965-1971, 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 1960-1970 was 5% of gross growth for softwood growing stock, and 7% of gross growth for softwood saw timber (Ferguson and Kingsley, 1972). As the spruce budworm prompts more landowners to turn to partial cutting, wind damage is becoming increasingly serious in Maine.
