Aspen seedlings do not thrive in the shade, and it is difficult for seedlings to establish in an already mature aspen stand. Fire indirectly benefits aspen trees, since it allows the saplings to flourish in open sunlight in the burned landscape, devoid of other competing tree species.

Aspen can reach an age of 200 years. [3] It is a very hardy species and tolerates long, cold winters and short summers. [citation needed] Aspen is resistant to browsing pressure by fallow deer owing to its unpleasant taste. [10] This species is important for the hornet moth, which uses it as a host during the larval stage. [citation needed]

Within the United States, the Official Register of Champion Trees defines the largest trees in a species-specific way; in this case, Pando is the largest aspen tree (Populus tremuloides). In forestry, the largest trees are measured by the greatest volume of a single stem, regardless of species.
Quaking aspen (Populus tremuloides) is the predominant species in aspen stands in the Great Lakes region, but bigtooth aspen dominates on drier, upland sites. Aspen stands dominated by bigtooth aspens are generally more open than those dominated by quaking aspens. It is more disease resistant than P. tremuloides.
