This successional model called FIRE-BGC simulates long-term stand dynamics on coniferous forest landscapes of the Northern Rocky Mountains. This model can be used to investigate cumulative fire effects for various fire scenarios, including prescribed burning, fire exclusion, & historical fire regimes. FIRE-BGC is an individual tree model FIRESUM with the mechanistic ecosystem biogeochemical model FOREST-BGC. Ecological processes that act at a landscape level, such as fire & seed dispersal, are simulated annually from stand & topographic information contained in spatial data layers.
