Key Findings: Efforts to produce resistant forests of more diversified age-classes will more likely succeed as the areas under management become larger.
Key Findings: Fir, the primary host of the budworm, is here to stay and while we may reduce its representation in our stands, it will always be sufficient to provide a food source for the budworm; silvicultural practices may reduce the losses from budworm attack, and can reduce the impact of the budworm on our total production by promoting rapid growth in new stands.
