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