Recently, aspen populations have been declining in some areas ("Sudden Aspen Death"). This has been attributed to several different factors, such as climate change, which exacerbates drought and modifies precipitation patterns. Recruitment failure from herbivory or grazing prevents new trees from coming up after old trees die.
Pando, a colony of quaking aspen, is one of the oldest-known clonal trees. Recent estimates of its age range up to 14,000 years old, and 16,000 years by the latest (2024) estimate. [1] It is located in Utah, United States. This is a list of the oldest-known trees, as reported in reliable sources. Definitions of what constitutes an individual ...
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.

Earlier sources argued germination and successful establishment of aspen on new sites was rare in the last 10,000 years and therefore, Pando's root system was likely over 10,000 years old. [7] More recent observations, however, have shown seedling establishment of new aspen clones is a regular occurrence and can be abundant on sites exposed by ...
Populus tremula (commonly called aspen, common aspen, Eurasian aspen, European aspen, or quaking aspen) [2] is a species of poplar native to cool temperate regions of the Old World. Description [ edit ]
The threat to aspens is so great that researchers see a future where the trees no longer grow in the Southwest. A fast-moving infestation of tiny insects threatens the survival of Arizona's aspen ...
Pando is a clonal colony of Populus tremuloides (quaking aspen) trees in south-central Utah, United States, that is estimated to be several thousand years old, possibly as much as 14,000 years. [49] Unlike many other clonal "colonies", Pando's above-ground tree trunks remain connected to each other by a single massive subterranean root system.
