A Review of Entomological Survey and Assessment Techniques used in Regional Spruce Budworm, Choristoneura fumiferana (Clem.) Surveys and in the Assessment of Operational Spray Programs

Problem Addressed: Spruce Budworm
Goal(s)/Objective(s): Ensure on a technical level the general principles of survey and assessment techniques were understood and evaluated in a manner unlikely to cause problems between jurisdictions, and create a sufficient standardization of techniques to allow a realistic comparison of results across jurisdictions.
Key Findings: Differences which existed were only minor and usually reflected modifications to suit local conditions or needs and standardization seemed unnecessary.

A Demonstration of Bacillus Thuringiensis, Plus the Enzyme Chitinase, Against the Spruce Budworm in Maine. Part I. Efficacy

Problem Addressed: Spruce Budworm in northern Maine
Goal(s)/Objective(s): Evaluate Bacillus thuringiensis and B.t. plus chitinase on controlling damage of the spruce budworm in northern Maine.
Key Findings: The B.t. alone treatments showed levels of crown damage that were indistinguishable from that of control plots.

Dynamics of Coarse Woody Debris Following Gap Harvesting in the Acadian Forest of Central Maine, U.S.A.

Problem Addressed: Dynamics of coarse woody debris (CWD) under an expanding-gap harvesting system in the Acadian forest of Maine
Goal(s)/Objective(s): Comparing volume, biomass, diameter-class, and decay-class distributions of CWD in permanent plots before and 3 years after harvest
Key Findings: The trend is likely more complex than what was determined due to the superimposition of small-scale natural disturbances and repeated silvicultural entries.

Disturbance Dynamics of Old-Growth Picea rubens Forests of Northern Maine

Problem Addressed: How spatial and temporal aspects of past disturbances shaped the current structure and composition of old-growth Picea rubens forests
Goal(s)/Objective(s): Linking spatial data and temporal data to reconstruct the location and size of former canopy gaps back to 1920, and determine a more general disturbance as far back as 1740.
Key Findings: Persistence of Picea rubens is attributed to the abundance of advance regeneration, the ability to endure suppression and respond favorably to release, and longevity relative to ecologically similar species.

The Efficacy of Salvage Logging in Reducing Subsequent Fire Severity in Conifer-Dominated Forests of Minnesota, USA

Problem Addressed: Secondary uses for salvage logging.
Goal(s)/Objective(s): Assess the impacts of blowdown and salvage logging on wildfire severity
Key Findings: Salvage logging reduced the intensity (heat released) of the subsequent fire, but the effect on severity (impact to the system) differed between the tree crowns and forest floor.

Stand and Cohort Structures of Old-Growth Pinus Resinosa-dominated Forests of Northern Minnesota, USA

Problem Addressed: Range of variability in stand and age structure of old-growth Pinus resinosa
Goal(s)/Objective(s): Use dendrochronological data to map stem locations and reconstruct stand and age structures prior to European settlement of the region.
Key Findings: Pre-settlement forests more complex than those of the single-cohort, post-stand-replacing-fire model that has guided regional forest management.

Residence Times and Decay Rates of Downed Woody Debris Biomass/Carbon in Eastern US Forests

Problem Addressed: Describing forest carbon dynamics and downed woody debris
Goal(s)/Objective(s): Develop models to estimate duration in various stages of decay, half-life, residence time, and decay rate for 36 tree species
Key Findings: Species that exhibited shorter half lives tended to display a shorter residence time and larger decay rate.

Quantifying Carbon Stores and Decomposition in Dead Wood: A Review

Problem Addressed: Differences in sampling and quantification of dead wood.
Goal(s)/Objective(s): Review methods for quantifying dead wood in forest ecosystems, with an emphasis on biomass and carbon attributes.
Key Findings: Identifies key research needs and knowledge which at present impeed our ability to accurately characterize dead wood populations.

Forest Management for Mitigation and Adaptation to Climate Change: Insights from Long-term Silviculture Experiments

Problem Addressed: Climate change effects on forest management
Goal(s)/Objective(s): Address the need of a management regime that simultaneously achieves adaptation and mitigation
Key Findings: Identified trade-offs between achievement of mitigation and adaptation objectives between each study
