Fire Regime Groups
The Fire Regime Groups layer represents an integration of the spatial fire regime characteristics of frequency and severity simulated using the vegetation and disturbance dynamics model LANDSUM (Keane and others 2002). These groups are intended to characterize the presumed historical fire regimes within landscapes based on interactions between vegetation dynamics, fire spread, fire effects, and spatial context (Hann and others 2004). Fire regime group definitions have been altered from previous applications (Hann & Bunnell 2001; Schmidt and others 2002; Wildland Fire Communicator’s Guide) to best approximate the definitions outlined in the Interagency Fire Regime Condition Class Guidebook (Hann and others 2004). These definitions were refined to create discrete, mutually exclusive criteria appropriate for use with LANDFIRE’s fire frequency and severity data products.
The fire regime groups mapped by LANDFIRE include the following:
- Fire Regime I (0 to 35 year frequency, low to mixed severity)
- Fire Regime II (0 to 35 year frequency, replacement severity)
- Fire Regime III (35 to 200 year frequency, low to mixed severity)
- Fire Regime IV (35 to 200 year frequency, replacement severity)
- Fire Regime V (200+ year frequency, any severity)
