Equations for estimating biomass of single trees by their major components were developed for ten Ontario softwood species. These equations, based on diameter at breast height outside bark and total tree height, directly estimate the ovendry mass. Equations for predicting ovendry mass percentages of the merchantable and unmerchantable components of the stem were also developed. These are based on merchantable top diameter and diameter at breast height outside bark, or merchantable height and total tree height.
