Abstract

The average biomass of big sagebrush (Artemisia tridentata Nutt.), antelope bitterbrush (Purshia tridentata (Pursh) DC.), snowbrush ceanothus (Ceanothus velutinus Dougl. ex Hook.), and greenleaf manzanita (Arctostaphylos patula Greene) was 6.1, 5.1, 10.7, and 16.2 tons per acre (13.9, 11.3, 24.0, and 36.0 tonnes per hectare), respectively, for 100-percent shrub crown coverage. Biomass by fuel size class and category is tabulated for percentage of crown cover.
