The Wood And Bark Biomass And Production Of Populus Tremuloides, Abies Lasiocarpa And Picea Engelmannii In Northern Utah, George L. Zimmerman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Thirty-two engelmann spruce (Picea engelmannii) 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. …
