From: Spatially and Temporally Variable Fire Regime on Rincon Peak, Arizona, USA
Multiple evidence of a stand-replacing fire in 1867 in stands just south of Rincon Peak in southeastern Arizona. (a) Evidence include (1) fire-scars recorded by two surviving trees, (2) death-dates and outer most rings just prior to 1867, and (3) even-aged ponderosa pine structure following the last fire in 1893. Even-aged forest structure is from two age-structure plots located within fire history plots 13 and 18. After the 1867 crown fire forests in south-facing aspects were converted to oak-shrub fields (b) while north-facing aspects have regenerated with even-aged pine forests (c).
