A Study of the Cost of Strip Cutting Black Spruce Stands in Northern Ontario

Problem Addressed: Spruce budworm

Goal(s)/Objective(s): Deal with the impact of strip cutting on planting, layout and supervision, in-strip operations, roadside processing, movement of mean and materials, and roads.

Key Findings: While the effects of strip cutting on silvicultural treatment costs are not included in the terms of reference of this study, discussions with foresters suggest that there may be some.

Summary Report on Studies of the Impact of Insecticides on Forest Ecosystems

Problem Addressed: Insecticide impacts on forest ecosystems

Goal(s)/Objective(s): Examine forest songbird responses to timber stand alterations in Eastern Canada caused by spruce budworm damage over the past decade.

Key Findings: In areas where the budworm-killed conifer component is being replaced by a new forest growth, songbird density is comparable to that in adjacent undamaged stands, but songbird diversity is considerably lower than in nearby unaffected stands.

Insecticide Trials to Control Spruce Budworm Damage on Christmas Trees

Problem Addressed: Spruce budworm and use of insecticides effecting Christmas trees

Goal(s)/Objective(s): Describe the tests of experimental applications of three chemicals to provide data for new registrations.

Key Findings: Fall and winter predictions of high populations and potential heavy budworm damage in southern Maine were inaccurate.

Effects of Insecticides

Problem Addressed: Effects of insecticides

Goal(s)/Objective(s): Organize remarks on 'the pesticide problem' and pesticides effects on non-target organisms.

Key Findings: Adopting ecologically sound insect-pest management using modern integrated control systems will help reduce genetic toxicity to experimental animals and will work against how insecticides are frequently counterproductive in achieving the intended objective of controlling insect populations.
