Equations are given for estimating fresh and ovendry weights of biomass components for seven major Maritimes tree species (balsam fir, white spruce, red/black spruce, jack pine, red maple, white birch, and trembling aspen). Two equations are given for each component, one using diameter at breast height (DBH) alone as the independent variable, and the other using both DBH and height. A set of stump biomass equations are included which use DBH and stump height as independent variables. These equations are based on l-400 sample trees from throughout New Brunswick and Nova Scotia. Stem disc and branch samples were oven-dried and used to estimate ovendry/fresh weight ratios for each sample tree. A FORTRAN subroutine is included to assist in tree biomass calculations.
