Aspen trees, specifically the quaking aspen (Populus tremuloides), typically have a lifespan of around 30 to 50 years, though some individuals can live up to 100 years under ideal conditions. They often grow in clonal groves, where a single root system can produce many trunks, allowing the genetic material to persist even when individual trees die. Factors such as environmental conditions, disease, and competition can influence their longevity.
