Key Findings: Overall level of harvest of spruce-fir pulpwood in Maine did not change much from 1967 to 1976, although spruce-fir sawlog production more than doubled.
Goal(s)/Objective(s): Discussion of the spruce budworm in eastern North America
Key Findings: Many facts about spruce budworm biology and behavior suggest that its long-term success is not closely tied, to individual trees or even stands--as are some less mobile insects, such as scales and even sawflies
Key Findings: Efforts to produce resistant forests of more diversified age-classes will more likely succeed as the areas under management become larger.
Goal(s)/Objective(s): Describe a further improvement in handling techniques and equipment necessary to produce large numbers of second-instar larvae to satisfy current demands
