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.

Modelling Primary Branch Frequency and Size for Five Conifer Species in Maine, USA

Problem Addressed: Crown Structure

Goal(s)/Objective(s): Test for species differences in maximum branch diameter profile, branch density, and relative branch diameter distribution.

Key Findings: There is a range of variability in key crown structural attributes due to inherent species differences, but models fit across multiple species can perform quite well as the amount of explained variation was relatively high.

Stand Structure and Composition 32 Years after Precommercial Thinning Treatments in a Mixed Northern Conifer Stand in Central Maine

Problem Addressed: Precommercial thinning on an even-aged northern conifer stand in Maine

Goal(s)/Objective(s): Examination of stand structure and composition 32 years after treatment.

Key Findings: Early thinning treatments were found to have long-term effects on key stand attributes, even more than 30 years after treatment in areas with mixed species composition and moderate site potential.

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.

Northern tamarack: unused resource?

Problem Addressed: Describes extent of tamarack in North, and potential market options

Goal(s)/Objective(s): Assess area and volume of tamarack and describe markets

Key Findings: Resource is not large but generally underutilized; tamarack area once much larger

Recommendation: Tamarack suited to uses in the round, small mills, small logging operations

Spruce budworm returns to Northeast

Problem Addressed: Current status of Spruce fir forests in NY, VT, NH, and ME

Goal(s)/Objective(s): DEscribe extent and condition of region's spruce fir forests and timber supply

Key Findings: Most of the spruce fir area is in Maine; an large surplus is in the 21-40 yr age class

Recommendation: Land managers need to prepare in advance for possible budworm outbreak

Developing optimal commercial thinning prescriptions: A new graphical approach

Problem Addressed: Thinning prescriptions for intensive management of stand density

Goal(s)/Objective(s): Develop an analytical framework to facilitate the application of existing stocking diagrams and stand-growth simulators in formulating density-management regimes

Key Findings: Graphical techniques such as ThinME allow forest managers to effectively explore a variety of commercial thinning prescriptions.
