Silvicultural Practices for Control of Spruce Budworm
Abstract:Some 30-40 years ago a severe outbreak of spruce budworm in Canada and in Maine caused very heavy losses. Maine alone lost an estimated 25,000,000 cords of spruce and fir. With a new destructive outbreak in Canada and the Adirondacks, attention is being focused on applying the silvicultural theories worked out during the earlier attack. The writer sketches how this might work out in a typical spruce-fir stand.
