Abstract

Within the framework of large-scale forest management, the application of Eichhorn's law, which employs dominant height or mean height exclusively to predict tree volumes per hectare, is certainly rapid, but high accuracy is not guaranteed. Substantial error occurred when this method was used in a study of boreal black spruce stands (Picea mariana (Mill.) B.S.P.). Use of both basal area per hectare and dominant height, however, permitted estimation of total volume per hectare and volume to 9 cm top with only 11 and 12% error, respectively. The form factors for total volume and volume to 9 cm top showed great stability. For this reason, use of the simple conventional formula (V = G.H.F.) to estimate standing volumes is justified.
