Influence of harvest gaps and coarse woody material on click beetles (Coleoptera: Elateridae) in Maine’s Acadian forest

Goal(s)/Objective(s): To examine how the species richness, abundance, diversity, and assemblage of similarity of click beetles inhabiting coarse woody material were affected by harvesting and coarse woody material characteristics.
Key Findings: Small (less than 0.2 ha) harvest gaps with living trees retained throughout the gap can maintain click beetle assemblages similar to that of an unharvested forest.

The role of herbicides for enhancing forest productivity and conserving land for biodiversity in North America

Problem Addressed: Do herbicides increase forest productivity, and are they compatible with the objectives of wildlife management and biodiversity conservations?
Key Findings: If herbicides are properly used, current research indicates that the negative effects on wildlife are usually short-term and that herbicides can be used to meet wildlife habitat objectives.

Benchmarking and Calibration of Forest Vegetation Simulator Individual Tree Attribute Predictions Across the Northeastern United States

Goal(s)/Objective(s): Benchmark and calibrate three submodels of the Forest Vegetation Simulator-Northeast variant (FVS-NE).
Key Findings: An assessment of overall model performance should be conducted if calibrated submodels are used and alternative modeling strategies be explored to better represent the allometry and growth of the important trees species across the northeastern United States.

Comparing Strategies for Modeling Individual-Tree Height and Height-to-Crown Base Increment in Mixed-Species Acadian Forests of Northeastern North America

Problem Addressed: Lack of prediction methods for annual tree height increment and height-to-crown base increment.
Key Findings: There is an advantage to incorporating species as a random effect in individual-tree models and the effectiveness of modeling tree crown recession directly for application in mixed-species forest growth and yield models was demonstrated.

Brown needles Lessons from SBW Outbreak of 70’s and 80’s

Problem Addressed: Lessons learned.
Goal(s)/Objective(s): Informal summary on issues.
Key Findings: Forest, industry, and pest control options have all changed. WE have one well observed outbreak but next one may be different.
Recommendation: Continue the march already begun by State with intense early monitoring, and industry and University with planning, education, and information.

Assessing and Modeling Standing Deadwood Attributes Under Alternative Silvicultural Regimes in the Acadian Forest region of Maine, USA

Problem Addressed: Standing Deadwood in Forests
Goal(s)/Objective(s): Snags in various stages of decay were inventoried across eight silvicultural treatments in eastern spruce–fir forests in central Maine nearly 60 years after treatments were initiated. Several modeling strategies were developed to estimate number of snags per hectare in various stages of decay.
Key Findings: Help with reducing disparities between observed and modeled snag stocking levels and further understanding of relationships between live and standing dead trees inherent to eastern spruce-fir forests.

Estimates of Downed Woody Debris Decay Class Transitions for Forests Across the Eastern United States

Problem Addressed: Decay status being categorized by visual/structural attributes, not temporal transitions between DWD.
Goal(s)/Objective(s): Use a repeated DWD inventory across the eastern US to estimate decay class transitions to inform DWD dynamics across this broad geographic region
