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