The LANDFIRE Fire Regime Groups (FRG) product characterizes 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 to best approximate the definitions outlined in the Interagency Fire Regime Condition Class Guidebook.
At the release of LF 2016 Remap Fire Regime Groups (FRG_NEW) was included as an attribute in the Biophysical Settings (BPS) product. Then, in calendar year 2024, this product became a stand-alone product once again.
