An Economic Analysis of Southern Pine Beetle Suppression Activity on the Gulf Coastal Plain National Forests During 1985 and 1986.

Problem Addressed: The Southern Pine Beetle

Goal(s)/Objective(s): Analyze the efficiency of SPB suppression on the Gulf Coastal Plain national forests.

Key Findings: SPB suppression projects on the national forests in the Gulf Coastal Plain were economically justified during 1985 and 1986; and greater benefits and efficiency were achieved for greater average spot-size controlled.

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.

An Important Unknown in Interpreting the Infestation Dynamics of the Spruce Budworm

Problem Addressed: Spruce Budworm

Goal(s)/Objective(s): Provide a change of pace in proceedings of the Forum and stretch imaginations for improving forest pest management strategies

Key Findings: The precise time of moth dispersal became known though incidental observation in Petawawa

Analysis of Relative Benefits of the Spruce Budworm Control Program

Problem Addressed: Spruce Budworm

Goal(s)/Objective(s): Measure the loss of the public sector relative to the losses of the private sector that would be incurred if the spruce budworm epidemic is not controlled in the 1976 proposed project area.

Key Findings: The relative losses and benefits accruing to public and private interest from a Budworm Management Program are the basis for determining the equitable burden.

Analysis of the 1979 Check Cruise of the Maine Spruce Budworm Growth Impact Study

Problem Addressed: Double checking the accuracy and uniformity of measurements between and among crews providing data to the Maine Spruce Budworm Growth Impact Study

Goal(s)/Objective(s): Report the analysis of the check cruise data obtained during August and September, 1979.

Key Findings: Results of the 1979 check cruise appear to be comparable to those of the 1975 check cruise conducted by James W. Sewall Company
