Nutrient Concentration of Down Woody Debris in Mixedwood Forests in Central Maine, USA

Problem Addressed: Nutrient concentrations pre- and post-harvest pool sizes across down woody debris decay.
Goal(s)/Objective(s): To determine the nutrient concentrations
Key Findings: Softwoods generally had lower nutrient concentrations and higher C:N-ratios than hardwoods; N:P-ratios did not differ between hardwoods and softwoods.

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.

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.

MODELING BIOMASS AND NUTRIENT DYNAMICS IN MAINE BALSAM FIR STANDS: INFLUENCE OF INCREASED SILVICULTURAL INTENSITY ON FOREST SUSTAINABILITY

Problem Addressed: Intensive forest harvesting impacts on site productivity.
Key Findings: This analysis indicated that relative risk of depletion of plant-available nutrients was Ca>K>P>Mg. If N remains the most commonly deficient nutrient in forests of the region today, then accelerated rates of N removal were also a potential concern.
Recommendation: Evaluate site conditions and soil suitability as part of intensive harvesting prescriptions.
