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: 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.
