Impacts of Air Pollution on Forest Ecosystems (1980)

Problem Addressed: Air pollution
Key Findings: Air pollutants induce changes that do not produce visible injury symptoms but adversely affect growth, yield and quality of plants and plant products. A better understanding is needed of the nature of pollutants and variations in their amounts at given sites.

Assessment of the 1971 Spruce Budworm Aerial Spraying Program in New Brunswick and Forecast for 1972.

Problem Addressed: Spruce budworm
Goal(s)/Objective(s): Discuss and review the 1971 Spruce Budworm aerial spraying program and suggest proposals for 1972.
Key Findings: The trends suggest that the biocontrol complex operating against the budworm has been weakened, and that spraying may lead to higher general equilibrium levels of budworm, so that resurgence becomes more probable; so far, no minor pest is opportunistically approaching epidemic status. However, spray-induced interference with biocontrol forces leaves this possibility open.

Degrade and Decay of Spruce-Fir Timber Following Spruce Budworm Attack (1978)

Problem Addressed: Spruce budworm destruction of over 300 million cords of balsam fir pulpwood and saw timber, with demand for balsam fir increasing continually.
Goal(s)/Objective(s): Information presented as a summary of what is known about spruce budworm-caused degrade and decay of balsam fir and, to a lesser extent, spruce.

Environmental Studies in the Use of Accothion for Spruce Budworm Control (1971)

Problem Addressed: Effect on wildlife from spraying against Spruce Budworm
Goal(s)/Objective(s): Effects of the insecticide Accothion birds, mammals, fish, and amphibians
Key Findings: Observations in the spray area were made on reactions to Accothion of a great variety of species of flora and fauna present. Accothion showed observable effects on some insects but not on other insects; nor on plants, birds, minnows in a confined pool, tadpoles, frogs, toads, and salamanders.
