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.

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

Species Differences in Total and Vertical Distribution of Branch- and Tree-Level Leaf Area for the Five Primary Conifer Species in Maine, USA

Problem Addressed: Distribution of Leaf Area
Goal(s)/Objective(s): Examine species variation in total and vertical distribution of projected leaf area at the individual branch- and tree-levels.
Key Findings: Differences in total and vertical distribution of leaf area exist between species, but significant amounts of their variation are largely accounted for by bole and crown size.

Effect of gap harvesting on epiphytes and bark-dwelling arthropods in the Acadian forest of central Maine

Problem Addressed: Epiphyte and Arthropod Communities
Goal(s)/Objective(s): To determine effects on epiphyte and anthropod communities from red maple trees
Key Findings: Arthropod and epiphyte assemblages dwelling on the bark of red maple trees located in undisturbed forest and harvest gaps varied with height.Canonical correlation analysis revealed a positive association between bryophytes, Collembola, and Araneae. A strong correlation between Collembola and Araneae suggested a possible trophic interaction that may be affected by gap harvesting through a reduction in bryophyte abundance.
