Total stem green-weight biomass equations are given for four northeastern softwood species and ten northeastern hardwood species groups. Data, compiled from studies conducted in New York, New Hampshire, Michigan, Ohio, and two independent studies in West Virginia, suggest that for some data sets there were regional differences for species group. The regional differences may reflect differences in stem form, site quality, and moisture content of the trees due to soil moisture and seasonal variation in data collection analysis.
