    Description

    We investigated the distribution of biomass and nutrients in lodgepole pine (Pinus contorta var. murryana Dougl.) ecosystems on pumice soils in south-central Oregon. Sixty-three trees were sampled to develop equations for estimating dry weights of tree crowns, boles, bark, and coarse roots from diameter at breast height and height. The concentrations of total carbon, nitrogen, phosphorus, and sulfur were determined for each of these components. Biomass, nutrient concentrations, and nutrient contents of the associated vegetation, forest floor, woody debris, fine roots, and soil horizons also were determined. An example stand illustrates the use of these data for determining the effects of bole versus whole-tree harvesting on nutrient capital in a lodgepole pine ecosystem.
