Fire Regime Groups

The Fire Regime Groups (FRG_NEW) 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.

In LF Remap, Fire Regime Groups (FRG_NEW), Percent of Low-severity Fire (PRC_SURFAC), Percent of Mixed-severity Fire (PRC_MIXED), Percent of Replacement-severity Fire (PRC_REPLAC), and Fire Return Interval (FRI) are included as attributes in Biophysical Settings products.

(Why is the CSV important?)
