Problem Addressed: Forested wetlands in Maine.
Goal(s)/Objective(s): Analyze, revise, and test a Geographic Information System (GIS) rule-based model to improve the mapping of forested wetlands in Maine.
Key Findings: Evaluation of new variables in the model (e.g. topographic position) and the effect of spatial error propagation in developing the GIS data base need to be investigated further.

Problem Addressed: Pressure treatment of transmission poles.
Goal(s)/Objective(s): Develop a mathematical model to simulate the movement of fumigants in spruce poles in service. The model is designed to be used in planning for proper re-treatment schedules and for comparing different fumigant formulations and application methods.
Key Findings: Diffusion coefficients and effective transfer coefficients of two commonly used fumigants, methyl isothiocyanate and chloropicrin, in red spruce wood were measured.

Problem Addressed: Black Spruce variance
Goal(s)/Objective(s): Identify the families and individuals having the best height growth at age 13 and estimate the heritability of the trait, to determine whether the genotype-environment interaction is significant, to determine if there are significant differences in height between progeny of fast-growing parent trees and progeny of slower-growing parent trees, or among different stands, to determine whether selection is effective at early ages, to determine if family differences affect cone production and to estimate heritability for this trait, and to determine if family differences affect seed viability.
Key Findings: These 13-year-old black spruce progeny tests provide valuable information useful in determining proper strategies for growth improvement for the next generation of this species.

Problem Addressed: Composition of forested mountain slopes in western mountain biophysical region of Maine and how it is effected by soil/site properties
Goal(s)/Objective(s): 1. Determine if a system of habitat types (HT's), developed for the White Mountain National Forest of New Hampshire, accurately describes the soil/site characteristics of mountain slopes in western Maine; and 2. to determine if species composition is similar on corresponding HT's, in Maine and New Hampshire.
Key Findings: Tree species composition varies among the HT's observed on mountain slopes in western Maine. The composition of understory herbaceous and woody vegetation did not appear to differ across HT's.

Problem Addressed: Variation in predicted biomass from alternative approaches
Goal(s)/Objective(s): Compare the most common methods by species, stand, and county levels
Key Findings: Biomass differs dramatically depending on the approach and spatial level examined
Recommendation: Treat biomass estimates with caution and use method that is best documented
