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.

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]
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.
Populus is a genus of 25–30 species of deciduous flowering plants in the family Salicaceae, native to most of the Northern Hemisphere.English names variously applied to different species include poplar (/ ˈ p ɒ p l ər /), aspen, and cottonwood.
Pando aspen grove at Fishlake National Forest. Pando (from Latin pando 'I spread') [1] is the world's largest tree, a quaking aspen (Populus tremuloides) located in Sevier County, Utah, United States, in the Fishlake National Forest.
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 ...
By contrast, the (roughly) 300-year-old Ice Glen pine in Stockbridge, Massachusetts shows approximately half the annual growth rate of trees in the 90- to 180-year age range, averaging just 5.8 cubic feet (0.16 m 3) per year over a five-year monitoring period. Volume increased as a result of increases in both height and girth.
