A complete Fire Regime Synthesis for Madrean pine–oak–juniper communities has not yet been published in the Fire Effects Information System. However, information is available from LANDFIRE succession modeling of Madrean pine–oak–juniper Biophysical Settings (BpS).
Table 1 summarizes LANDFIRE data on Madrean pine–oak–juniper BpSs, and figure 1 shows where they occur. Appendix A
lists the Madrean pine-oak-juniper BpSs and the results of LANDFIRE succession modeling for each.
| Table 1—Range of modeled historical mean fire intervals and percentage of historical fires in each of three fire severity classes for Madrean pine–oak–juniper Biophysical Settings (BpS), and the number of these BpSs in each fire regime group [2]. See Appendix A for details specific to each BpS. | |||||||||
| Mean Fire Interval (years) | Replacement-severity Fires (%) |
Mixed-severity Fires (%) | Low-severity Fires (%) | Fire Regime Group I |
