Spruce Budworm on Christmas Trees

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

Goal(s)/Objective(s): Control of insects on Christmas trees

Key Findings: Trees damaged by budworm or other insects should not be cut because if they are left for a few years they will often recover and become suitable for Christmas trees.

Photometric Derivation of Analytical Parameters for Large Area Forest Management

Problem Addressed: Spruce budworm infestation in northeastern Canada and the United States

Goal(s)/Objective(s): Derive photometric parameters from historical satellite (Landsat) data toward an ultimate objective of aiding large area forest managers to cope with the massive spruce budworm infestation in northeastern Canada and the United States.

Key Findings: Use of satellite data (Landsat MSS) to measure and predict mortality as well as other analytical parameters related to coniferous forest management appears technically feasible.

Recommendation: A development effort be initiated with Maine's Department of Conservation to complement Maine's present Landsat Demonstration Program with the National Aeronautics and Space Administration for establishment of a mechanism for small forest landowners to benefit from satellite data.

Planning Now to Reduce, Postpone or Prevent the Next Spruce Budworm Outbreak

Problem Addressed: Spruce budworm

Goal(s)/Objective(s): Introduces new entomological concepts, and asks as well as suggests how they may be used to develop an international strategy to reduce, postpone or perhaps even prevent future outbreaks from occurring through at least part of the range of the spruce budworm in North America

Key Findings: Ten general characteristics of spruce budworm infestation in Ontario are presented

Controlling Hardwood Sprouts with Foliage Sprays

Problem Addressed: Controlling unwanted hardwood reproduction

Goal(s)/Objective(s): A more effective, less destructive way to deal with the unwanted hardwood reproduction is necessary.

Key Findings: For forest management, fairly low percent kill with decreased rate of regrowth for 2 or 3 seasons may be adequate to give pine the release it needs.

The Spruce Budworm in Maine in 1972

Problem Addressed: Spruce budworm in Maine

Goal(s)/Objective(s): Determine what to do to combat the spruce budworm issue.

Key Findings: Ground and aerial surveys and airport procedures were conducted as reported in preceding reports by many of the same personnel, but with a change from a centralized to a regionalized system of administration.

An Assessment of Damage Caused by the Spruce Budworm on Spruce and Balsam Fir Trees in New Brunswick

Problem Addressed: Spruce budworm damage

Goal(s)/Objective(s): Assess sample pots on all ownerships in New Brunswick to determine the damage caused by spruce budworm

Key Findings: Damage to balsam fir was much greater than that of spruce and was highest on the small freehold ownership, especially in southern New Brunswick

Effects of Forest Management on Avian Abundance in Spruce-fir Forests of New England

Problem Addressed: The decline of several spruce-fir associated birds

Goal(s)/Objective(s): Determine how forest management is associated with mature forest structure and how abundance of focal species responds to mature forest structure

Key Findings: Forest management treatments reflect a range of vegetative structural conditions from mature reference stands with large diameter trees and relatively low shrub cover to clearcut stands with few large trees and high shrub cover.

Relationships Among Forest Management and Spruce Grouse (Falcipennis canadensis) Patch Occupancy and Abundance in Commercially-Managed Forests

Problem Addressed: Decline of spruce grouse populations

Goal(s)/Objective(s): To determine how the maturity, structure, and composition of the commercial forest affect spruce grouse occupancy and abundance.

Key Findings: Forest harvest practices that maintain and promote conifer regeneration should be implemented in both current, and historically, conifer-dominated stands.
