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.

Early Response of Balsam Fir to Spacing in Northwestern New Brunswick (1981)

Problem Addressed: Balsam fir development
Goal(s)/Objective(s): Describes the early development of young balsam fir/white spruce stands in northwestern New Brunswick which were spaced to several different levels of spacing, about 02 years ago.
Key Findings: Evaluation of "optimal" spacing levels will involve an economic analysis of such factors as cost of spacing, the relationship between merchantable yield and initial spacing, the influence of average tree size on logging costs, and relative costs and benefits of alternative silvicultural treatments such as fertilization.

Gone with the Wind: Silvicultural Methods for Reducing Wind Damage After Cutting in Spruce and Fir Stands (1979)

Problem Addressed: Wind as a damaging agent to forests.
Key Findings: Clearcutting should be regarded as a last resort, when neither the uniform or strip shelterwood approaches are possible, as well suggesting a more sophisticated silvicultural approach.

Harvesting Systems for Silvicultural Control of Spruce Budworm (1979)

Problem Addressed: Damage done by spruce budworm
Goal(s)/Objective(s): Using silviculture playing a major role in an integrated protection management program for reducing damage by the spruce budworm.
Key Findings: An analysis of a proposed partial cutting on a small private woodlot in southern Piscataquis County shows that shortwood methods, using the landowner's small farm tractor, are preferable in this case
