Antelope bitterbrush (Purshia tridentata) is a preferred browse species that is susceptible to decreases in population density due to fire. The reduction in density of this species due to fire was determined by sampling areas within and adjacent to the burn. The 1975 burn caused a significant reduction in the population density of bitterbrush. It was also determined that rate of growth was lower for plants within the burn.
