Percent of Mixed-severity Fire

The Percent of Mixed-severity Fire (PRC_MIXED) layer quantifies the amount of mixed-severity fires relative to low- and replacement-severity fires under the presumed historical fire regime. Mixed severity is defined as between 25 and 75 percent average top-kill within a typical fire perimeter for a given vegetation type.

LF 2016 Remap PRC_MIXED is an output of the recently revised Biophysical Settings (BpS) models for LF Remap (LF 2.0.0) and is now provided as an attribute of the BPS spatial layer. In previous versions, PRC_MIXED was an output of the original BpS models and provided as a separate spatial layer.
Note: There is no BPS for LF Remap AK.

PRC will not be produced for LF 2020 Update.
