Not only is vegetation altered but so is future fire behavior in increased fire frequency sites in sagebrush. Research conducted in basin big sagebrush communities at John Day Fossil Beds National Monument in central OR, compares sites burned once 15 yrs ago, 26 yrs ago, and sites burned twice. Repeated burns shifted composition from shrub‐dominated to prolonged native herbaceous dominance. Fifteen years following one fire, the native‐dominated herbaceous component was 44% a...nd live shrubs were 39% of total aboveground biomass. Aboveground biomass of twice‐burned sites (2xB; burned 26 and 15 yr prior) was 71% herbaceous and 12% shrub. Frequency and density of bluebunch wheatgrass and Idaho fescue were not modified by fire history, but Sandberg bluegrass was reduced by repeated fire, occurring in 84% of plots burned 26 yr prior, 72% of plots burned 15 yr prior, and 49% in 2xB plots. Cheatgrass frequency and density were not different with fire history. Modeled rates of fire spread in 2xB sites double that of once‐burned sites.
