Sammanfattning

The amount of biomass for fractions and distribution of sallow trees growing on forest land was studied. The allometric relationship between breast height diameter (DBH) and the weight of total tree, stem, branches and leaves was quantified. The studied trees were 37±14 (5-66) years old and the stem number 1030±727 (222-3000) stems ha-1. Equations for estimating the tree weight or the fractions from diameter at breast height (DBH) are presented. The mean total standing dry weight above stump level (» 200 mm) for sallow was 95±50 tonnes ha-1 with a range of 4-203 tonnes ha-1. In addition to estimating conventional dry weights of trees and tree components, SLA and PLA, among other measures, were estimated
