Species abundance over 90 years of continued contemporary climate compared to B1 and A2 climate change scenarios under suppressed, historical, and future fire regimes. The relative equilibrium of the area occupied by each species maintained under a continuation of the current climate and historical fire regime served as a baseline to compare simulated effects of alternative fire-climate scenarios. Under both the B1 and A2 climate scenarios, increasing fire frequency accelerated simulated climate-driven declines in Douglas-fir, lodgepole pine, and subalpine fir. Increasing fire frequency favored ponderosa pine similarly under all climate scenarios, though slightly more so under the B1 climate change scenario. Species occupancy is defined as the presence of at least one age cohort in a 1-ha grid cell
