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