Young aspen bark is an important seasonal forage for the European hare and other animals in

Aspen stands dominated by bigtooth aspens are generally more open than those dominated by quaking aspens. It is more disease resistant than P. tremuloides.
Systems of classification used to define large trees vary considerably, leading to some confusion about Pando's status. 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 ...
