DescriptionThe spruce budworm population in Maine's spruce-fir forests has been at epidemic levels since the early 1970's. Spruce-fir mortality in 1976-78 is compared with predictions of what mortality would have been had the natural mortality rates remained at the levels experienced before the budworm outbreak. It appears that mortality of spruce and fir has increased 2 1/2-fold since the 1960's, that is, 60 percent of the mortality can be attributed to the budworm outbreak.
