Dynamics: Due to the cool, moist environment of this plant association, fires are probably less frequent than drier types. Where Acer grandidentatum cover is luxuriant, understory herb growth may not be sufficient to carry a surface fire (Uchytil 1990d). When the Acer grandidentatum crown is killed by fire, some resprouting can occur, but sprouting vigor is thought to be low (Uchytil 1990d). In Utah, Acer grandidentatum has been observed to be expanding its range into stands of Quercus gambelii. One hypothesis to explain this recent migration is that fire suppression has favored Acer, since Quercus gambelii sprouting has not been as vigorous with the lower fire frequencies of the last century.
Environmental Description: It occurs on north slopes and streamside terraces at 1615 to 2195 m (5300-7200 feet) elevation.
Geographic Range: This association is presently known from the Galiuro Mountains (Coronado National Forest), Arizona.
