Landfire Fire Regime Groups

Metadata Updated: May 2, 2019

Historical fire regimes, intervals, and vegetation conditions are mapped using the Vegetation Dynamics Development Tool (VDDT). These data support fire and landscape management planning goals in the National Cohesive Wildland Fire Management Strategy, the Federal Wildland Fire Management Policy, and the Healthy Forests Restoration Act.The Fire Regime Groups (FRG) were intended to characterize the presumed historical fire regimes within landscapes based on interactions between vegetation dynamics, fire spread, fire effects, and spatial context. FRG definitions have been altered from previous applications to best approximate the definitions outlined in the Interagency Fire Regime Condition Class Guidebook. These definitions were refined to create discrete, mutually exclusive criteria appropriate for use with LANDFIRE's (LF) fire frequency and severity data products.

FRG is created by linking the Biophysical Settings (BpS) Group attribute in the BpS layer with the Refresh Model Tracker (RMT) data and assigning the FRG attribute. This geospatial product should display a reasonable approximation of FRG, as documented in the RMT. (LF 1.0.0 CONUS only used the vegetation and disturbance dynamics model LANDSUM) FRG can be used in landscape assessments.
