Overview:Categories: Deciduous, Fall Color
Quaking aspen is the most widely distributed tree of North America. It is fast-growing, relatively short-lived and commonly attains heights of 50-60 ft. This tree is very intolerant of shade and competition and is extremely susceptible to many types of damaging agents which at times may make it difficult to establish as transplants. It is found on many types of soil from moist loamy sands to shallow, rocky decomposing granite. When aspen stands are cut or burned, innumerable root suckers grow quickly from those roots less than 3 or 4 ft. deep.
Aspen is never used as a windbreak or snow fence tree due to its short life span and propensity to insect and disease problems. In addition, plants in the populacae family have soft wood which do not hold up well to heavy, wet snows.
Plant aspen from 6,000 to 11,000 feet where water and sunlight are abundant. May be planted as a wildlife habitat for winter forage of deer and elk, and nesting cavities for birds.
