Spruce Budworm Damage Assessment with 35mm Air Photos

Problem Addressed: Spruce budworm
Goal(s)/Objective(s): Assist forest managers at all levels in assessing damage and estimating possible future damage due to spruce budworm activity and provide an index which can be used to rank stands in terms of relative probability of future damage.

Potential for Prebunching with Small Wheeled Tractors

Problem Addressed: Slash from precommercial thinning creating an extreme fire hazard and serving as a breeding ground for insects.
Goal(s)/Objective(s): Utilize slash from precommercial thinning operations to meet part of the needs for wood fiber and energy.
Key Findings: A system that involves moving trees from the woods to a main skid trail with a small machine and moving the bunched materials from the skid trail to the landing with a larger machine is necessary.

The Effects of Fenitrothion, Matacil and Orthene on Frog Larvae

Problem Addressed: Effects of insecticides used for spruce budworm control on other wildlife.
Goal(s)/Objective(s): Discuss the behavioral repertoire of Rana clamitans tadpoles in the laboratory.
Key Findings: Concentrations detrimental to anuran larvae would never be encountered under normal operational applications of these chemicals.

Impact of the 1974-81 Spruce Budworm Infestation on the Forests of Cape Breton Island

Problem Addressed: Spruce budworm infestation on Cape Breton Island, Nova Scotia beginning in 1974.
Goal(s)/Objective(s): Determine what the overall effects of the SBW infestation on the Island forests was.
Key Findings: Volume of merchantable spruce/fir growing stock was reduced, degree of damage varied by covertype, and over half of the projected living merchantable spruce and fir trees died either during or immediately following the SBW attack.

Report of the 1986 Midcycle Resurvey of the Spruce-Fir Forest in Maine

Problem Addressed: Budworm outbreak effecting 1980 survey of supply and demand for spruce-fir in Maine.
Goal(s)/Objective(s): Validate the earlier forecasts and to update them to account for new or unexpected developments.
Key Findings: Maine forests, at least within the survey region, are adequately stocked with young trees.

Recommendations for Improvement of Spruce Budworm Population and Damage Survey Methods in the State of Maine

Problem Addressed: Spruce budworm in Maine
Goal(s)/Objective(s): Describe egg mass and defoliation survey; to check results of the egg mass survey, obtain more detailed information on budworm populations, and predict damage in the coming year.
Recommendation: Eliminate any branch beating surveys for spruce budworm and not using light trap data when populations are high.

Getting off the Treadmill: Some Public Concerns About Our Spruce Budworm Program

Problem Addressed: Spruce budworm
Goal(s)/Objective(s): Describe the position and what to do about the issues of the state's responsibility in controlling budworm damage to privately owned forest lands, whether we are on an endless treadmill of spraying, what is being done to the environment and public health in the long term
Key Findings: Spraying of the private sector will end by 1981, will begin promotion of the development of a forest less susceptible to budworm, and will cease using any insecticide that poses distinct dangers to fish or any other nontarget animal or plant.

Outcome-Based Forestry: A Case Study of the First Private Landowner’s Implementation of an Alternative to Maine’s Forest Practices Act

Goal(s)/Objective(s): Determine how participating landowners were incorporating OBF policy into their forest management planning and operations; learn how they were ensuring that the required outcomes under the agreement were being achieved; determine the effects of IW's enrollment in OBF, as perceived by their forest managers, upon IW as a corporation, upon society, and upon the foresters implementing the policy; determine if harvest plans created under the contraints of OBF produce lower rates of fragmentation compared to FPA harvest plans for the same landscape
Key Findings: OBF harvests more closely followed stand boundaries, fractured fewer stands, and maintained higher mean stand area, the spatial arrangement of harvesting is a critical factor in lowering fragmentation

Evaluating the Influence of Stem Form and Vigor on Product Potential, Growth, and Survival for Northern Commercial Hardwood Species

Problem Addressed: Understanding how defects influence product recover and value; growth and mortality.
Goal(s)/Objective(s): A revised tree classification system
Key Findings: Stem form and vigor are highly variable across hardwood species; both attributes have important implications on hardwood growth & yield.
Recommendation: 4 classifications of stem form, 2 classifications of risk
