Quaking aspen regenerated from seed after a stand replacement wildfire in the Chiricahua Mountains of southeastern Arizona. The wildfire had created gaps in the canopy so that aspen were able to establish from seed. Seedlings were found at a mean density of 0.17 m–2, 30 m or more from the nearest potential seed trees. Six clumps of aspen seedlings contained 18–186 trees, occupying areas of 145–500 square meters at densities of 0.09-0.27 m–2. White-tailed deer (Odocoileus virginianus) browsed 14.3% of the seedlings. Occasional sexual reproduction of aspen may be a general trait of the species throughout the western portion of its range in North America.
