Abstract
Thirty-two engelmann spruce (Picea enqelmannii) ranging in d.b.h. from 9.4 to 84.6 cm, twenty subalpine fir (Abies lasiocarpa) with d.b.h.'s from 8.1 to 58.8 cm, and twenty aspen (Populus tremuloides) ranging in d.b.h. from 4.5 to 48.2 cm. were destructively sampled in Northern Utah to construct wood and bark biomass and production prediction equations for above and below ground parts. These prediction equations were then applied to stand table data from 20 x 25 meter plots representing a sere that changes from subalpine meadow to aspen to fir to a 'climax' stand of spruce. The biomass production data along the successional stages were then used to test some of Odum's hypotheses regarding ecosystem development (Science 1969). In all biomass and production predictive equations diameter at breast height (1.38 meters) and its transformations was found to be the single best independent variable.
