A complete Fire Regime Synthesis for desert riparian communities has not yet been published in the Fire Effects Information System. However, LANDFIRE succession modeling of desert riparian Biophysical Settings (BpS) provides estimates of fire regime characteristics (see LANDFIRE Biophysical Settings section). Figure 1 shows where these BpSs occur.

Percentage 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%.
