The Rapid Assessment (RA) vegetation dynamics data help to synthesize the best available knowledge of vegetation dynamics and quantify the natural range of variability in vegetation composition and structure. Models consist of two components: (1) a comprehensive description and (2) a quantitative, state-and-transition (box) model, created in the public domain software VDDT (Vegetation Dynamics Development Tool; Beukema et al. 2003). RA vegetation models were based on a simple, standardized five-box model that combines three generic succession stages with two canopy cover classes. Each class is specifically defined for individual models. Variations on this standardized model were also developed. Models were developed...

All FRCC calculations were done in ArcGIS 9.3.1 with the FRCC Mapping Tool version 2.2.0, using Landfire Biophysical Settings (BpS) and Succession Class (S-Class) layers and the default Landfire Reference Condition table (LFnat_west). All calculations were performed at a 30-meter resolution. Input BpS and S-Class layers were downloaded using the Landfire Data Access Tool version 2.2 (configuration database version 1.27, feature database version 1.02). Three landscape levels were used in all calculations, the 4th, 5th and 6th field HUCs from the "Pacific NW Sixth Field Hucs" GIS layer from Bonneville Power Administration (Subbasins, Watersheds and Subwatersheds, resp.). FRCC Calculation Procedure For each of the...

Broad-scale alterations of historical fire regimes and vegetation dynamics have occurred in many landscapes in the U.S. through the combined influence of land management practices, fire exclusion, ungulate herbivory, insect and disease outbreaks, climate change, and invasion of non-native plant species. The LANDFIRE Project produces maps of simulated historical fire regimes and vegetation conditions using the LANDSUM landscape succession and disturbance dynamics model. The LANDFIRE Project also produces maps of current vegetation and measurements of current vegetation departure from simulated historical reference conditions. These maps support fire and landscape management planning outlined in the goals of the National...
