See Fire history of the Appalachian region: A review and synthesis [2] for detailed information on fire regimes of Appalachian mesic oak-pine communities. Further information is available from LANDFIRE succession modeling of Biophysical Settings (BpS). Table 1 summarizes LANDFIRE data on the BpSs in Appalachian mixed-hardwood communities. Figure 1 shows where they occur. Appendix A lists the BpSs and the results of LANDFIRE succession modeling for each BpS in Appalachian mixed-hardwood communities.

¹Average historical fire-return interval derived from LANDFIRE succession modeling (labeled "MFRI" in LANDFIRE).
²Percentage of fires in 3 fire severity classes, derived from LANDFIRE succession modeling. Replacement-severity fires cause >75% kill or top-kill of the upper canopy layer; mixed-severity fires cause 26%-75%; low-severity fires cause <26% [1,3].
³NA (not applicable) refers to BpS models that did not include fire in simulations.
