|Table 1. Modeled fire intervals and severities in California oak woodlands 
Fire severity² (% of fires)
Number of Biophysical Settings (BpSs) in each fire regime group
| ¹Average historical fire-return interval
derived from LANDFIRE succession modeling (labeled "MFRI" in LANDFIRE).
²Percentage of fires in 3 fire severity classes, derived from LANDFIRE succession modeling. Replacement-severity fires
cause >75% kill or top-kill of the upper canopy layer; mixed-severity fires cause 26%-75%; low-severity fires
cause <26% [1,2].
³NA (not applicable) refers to BpS models that did not include fire in simulations.
