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