The high stem turnover rate combined with the clonal growth leads to proliferation in aspen colonies. The high stem turnover regime supports a diverse herbaceous understory. [citation needed] Aspen seedlings in a nursery. Aspen seedlings do not thrive in the shade, and it is difficult for seedlings to establish in an already mature aspen stand.
Fast growth continues until the age of about 20 years, when crown competition increases. After that, growth speed decreases and culminates at about 30 years of age. 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]
Populus tremuloides is a deciduous tree native to cooler areas of North America, one of several species referred to by the common name aspen.It is commonly called quaking aspen, [2] [3] [4] trembling aspen, [2] [3] American aspen, [3] mountain or golden aspen, [5] trembling poplar, [5] white poplar, [5] and popple, [5] as well as others.

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.
In 1993, Fishlake National Forest began work on the "Aspen Regeneration Project", [23] installing fences to help control deer and elk who threatened to destroy the productive results of work to spur and protect new growth Today, 53 acres of Pando is protected by 8-foot fences to control populations of mule deer (Odocoileus hemionus) and elk ...
In contrast with many trees, aspen bark is base-rich, meaning that aspens are important hosts for bryophytes [9] and act as food plants for the larvae of butterfly (Lepidoptera) species—see List of Lepidoptera that feed on poplars. Young aspen bark is an important seasonal forage for the european hare and other animals
Oldest tree in Poland. The age of the tree was estimated based on the trunk circumference and growth rate assessed by taking a core from an undamaged part of the trunk. If the trunk is the result of the fusion of two or three trunks, its age may be younger. [64] Algarrobo Abuelo: 1,200+ Algarrobo Prosopis chilensis: Villa de Merlo, San Luis ...
