Predicting biomass of five shrub species in northeastern California.

摘要: Volume, crown dinmeter, and number of twiga were alI highly correlated with biomass individual shrub bitterbrusb (PwSlJo tridentufu (Pursh)DC), greenleaf manxanita (Arctostaphylos pat& Greene), big sagebrush (Artewhia tri&ntata NW.), snowbrush (Ceanothus v&tinus Doug. ex. Hook), end gray rabbitbrush (Chrysothawuws nauseosus (Pall.)Britton). These variables used to develop equations predict above-ground dry weigh% R, values varied from 0.76 0.98.
