    • LANDFIRE 2001 Refresh Biophysical Settings (BPS) AK

    Metadata Updated: December 10, 2025

    LANDFIRE's (LF) 2001 Biophysical Settings (BPS) product represents the vegetation system that may have been dominant on the landscape prior to Euro-American settlement. BPS is based on both the current biophysical environment and an approximation of the historical disturbance regime. Map units are based on NatureServe's Ecological Systems classification and represent the natural plant communities that may have been present during the reference period (Comer et al 2003). Each BPS map unit is matched with a model of vegetation succession which is used to estimate reference fire frequency and severity. LANDFIRE uses BPS to depict reference conditions of vegetation systems across landscapes and should not be regarded as a representation of existing vegetation.
