- Maine Forest Service
Ground and aerial surveys, conducted jointly by the Maine Forest Service and U.S. Forest Service in northern Maine, revealed an increase in both degree and extent of infestation by the spruce budworm in 1956. Noticeable defoliation, as mapped from the air, covered more than 3,000,000 acres in eastern and northeastern Maine. Traces of defoliation were noted by ground observers farther to the west and south, also. The general situation, while not at all alarming from the standpoint of injury to the trees, represented a considerable change entomologically from that in 1955.
