LANDFIRE (LF), Landscape Fire and Resource Management Planning Tools, is a
shared program between the wildland fire management programs of the U.S.
Department of Agriculture's Forest Service, U.S. Department of the Interior's
Geological Survey, and The Nature Conservancy.
Landfire (LF) 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 Mean Fire Return Interval (MFRI) layer quantifies the average period between fires under the presumed historical fire regime.
MFRI is intended to describe one component of historical fire regime characteristics in the context of the broader historical time period represented by the LANDFIRE (LF) Biophysical Settings (BPS) layer and BPS Model documentation.
MFRI is derived from the vegetation and disturbance dynamics model VDDT (Vegetation Dynamics Development Tool) (LF 1.0.0 CONUS only used the vegetation and disturbance dynamics model LANDSUM).
This layer is created by linking the BpS Group attribute in the BpS layer with the Refresh Model Tracker (RMT) data and assigning the MFRI attribute.
This geospatial product should display a reasonable approximation of MFRI, as documented in the RMT.
MFRI is used in landscape assessments.
The LANDIFRE Fire datasets include:
Fire Regime Groups (FRG) is intended to characterize presumed historical
fire regimes within landscapes based on interactions between vegetation
dynamics, fire spread, fire effects, and spatial context
Mean Fire Return Interval (MFRI) quantifies the average period between
fires under the presumed historical fire regime
Percent of Low-severity Fire (PLS) image quantifies the amount of
low-severity fires relative to mixed- and replacement-severity fires
under the presumed historical fire regime and is defined as less than 25
percent average top-kill within a typical fire perimeter for a given
vegetation type
Percent of Mixed-severity Fire (PMS) layer quantifies the amount of
mixed-severity fires relative to low- and replacement-severity fires under
the presumed historical fire regime, and is defined as between 25 and 75
percent average top-kill within a typical fire perimeter for a given
vegetation type
Percent of Replacement-severity Fire (PRS) layer quantifies the amount of
replacement-severity fires relative to low- and mixed-severity fires under
the presumed historical fire regime, and is defined as greater than 75
percent average top-kill within a typical fire perimeter for a given
vegetation type
Succession Classes (SClass) layer characterizes current vegetation conditions
with respect to the vegetation species composition, cover, and height ranges
of successional states that occur within each biophysical setting
Vegetation Condition Class (VCC) represents a simple categorization of the
associated Vegetation Departure (VDEP) layer and indicates the general level
to which current vegetation is different from the simulated historical
vegetation reference conditions
Vegetation Departure (VDep) indicates how different current vegetation on a
landscape is from estimated historical conditions. VDep is based on changes
to species composition, structural stage, and canopy closure.
