Effects of thinning on drought vulnerability and climate response in north temperate forest ecosystems

Problem Addressed: Do density reductions confer greater resistance and/or resilience to droughts?
Goal(s)/Objective(s): To assess how long-term forest density management reduced drought vulnerability.
Key Findings: Thinning generally enhanced drought resistance and resilience; however, this relationship showed a pronounced reversal over time in stands maintained at lower tree densities
Recommendation: Results confirm the potential of density management to moderate drought impacts on growth

Effects of Photoperiod and Size on Flight Activity and oviposition in the eastern spruce budworm (Lepidoptera: Torticidae)

Problem Addressed: Dispersal of adult females of eastern spruce budworm (Choristoneura fumiferana (Clem.))
Goal(s)/Objective(s): Determine effects of photoperiod on spruce budworm
Key Findings: The role of female activity as related to size and flight capability is therefore of potentially great significance in spruce budworm population dynamics and deserves further detailed investigation.

Distribution and presistence of fenitrothion residues in foliage, soil and water in larose forest.

Problem Addressed: Insecticide residues in Larose forest.
Goal(s)/Objective(s): Summarize an operational experiment carried out in Larose Forest to study the persistence of aerially applied fenitrothion and its metabolites (the oxon analgue and 4-nitro-cresol) in white spruce foliage, soil and water samples collected from sprayed areas.
Key Findings: Degradation and persistence of fenitrothion findings are in reasonable agreement with those for the same chemical used in N.B. forests.

A Review of Important Forest Insect and Disease Problems in the Terrace Bay District of Ontario 1950-1980

Problem Addressed: Terrace Bay District loss due to insects and diseases.
Goal(s)/Objective(s): Review signficant forest insects and diseases that have occurred in the Terrace Bay District between 1950 and 1980.
Key Findings: Information on insects and diseases that are capable of causing, or have caused, tree mortality or a reduction in growth.

A Biologically Active Analogue of the Primary Sex Pheromone Components of Spruce Budworm

Problem Addressed: Spruce Budworm
Goal(s)/Objective(s): Disruption of mating and of trap capture of spruce budworm
Key Findings: The 1, 12-pentadecadiene is an olefinic pheromone analogue for the spruce budworm that can duplicate to some extent the functioning of the primary sex-pheromone components.

LiDAR and Forestry: Opportunities, Challenges, and Future

Problem Addressed: LiDAR and structure for motion provide invaluable data on forests
Goal(s)/Objective(s): Describe potential uses and challenges of these 3D technologies
Key Findings: 3D will change how we inventory and make forest management decisions
Recommendation: Continued research and evaluation of 3D products is needed for full utilization

Nineteen percent of Maine in conservation

Problem Addressed: Describes history of public lands policy in Maine and relation to waters
Goal(s)/Objective(s): Describe ubique aspects of Maine's public lands history and current issues
Key Findings: Can't summarize in 10 words.
Recommendation: People concerned about conservation have to get active. Our political situation is a mess.

Identifying growth releases in dendrochronological studies of forest disturbance

Problem Addressed: Measuring growth releases for reconstructing historical disturbances
Goal(s)/Objective(s): Provide an alternative method for testing growth releases
Key Findings: This absolute-increase method has convenient properties that remedy the shortcomings of the percent-increase method.
Recommendation: No arithmetic method is likely to obviate the need to visually inspect each tree-ring series.
