Aboveground Dry Matter of Jack Pine, Black Spruce, White Spruce and Balsam Fir Trees at Two Localities in Ontario

Abstract

Standard equations for aboveground ovendry mass of jack pine, black spruce, white spruce, and balsam fir were developed for the components and for the whole tree of single stems grown in natural stands in Ontario. The relationships between the component and the stem wood ovendry masses and those between the ovendry and the green masses were determined. Distribution of ovendry mass within the stem wood of merchantable trees was established. Wood densities were calculated, and comparisons of stem wood ovendry mass were made between the equations developed here and those found in other reports.
