Fire Ecology

Table 2 Last widespread fire and mean fire intervals (MFI) for the Sierra los Ajos (Kaib 1998) and Huachuca Mountains (Danzer et al. 1996).

	Site	Last wide spread fire	MFI: all fires¹	MFI: 10 %	MFI: 25 %
Sierra los Ajos	Canon Evans	1977	3.63	4.05	8.06
Sierra los Ajos	Canon Oso	1972	3.18	3.92	5.23
Huachuca Mts.	Sawmill Canyon	1914	4.88	5.93	7.12
Huachuca Mts.	Pat Scott Peak	1899	2.96	5.13	9.75

¹ Mean Fire Interval (MFI) for all fires is based on total fires recorded at the sites, MFI 10 % represents fires recorded on 10 % or more of sampled trees, and MFI 25 % represents fire recorded on 25 % or more of sampled trees.
