Quaking aspen is the most widely distributed tree in North America and is found across most of Canada and the U.S. and into northern Mexico. It occurs in greatest density within Minnesota, Wisconsin, Michigan, central Canada, Colorado, Utah, Alaska, and Maine. This tree prefers cooler climates, and is found at higher elevations in the southern part of its distribution. The quaking aspen is best known for its distinctive white bark, deep green foliage that shakes in the breeze, and brilliant golden fall foliage color, and it often grows in groups that originate from a single individual. This species is an important food resource for a variety of animals, including deer, elk, moose, black bear, grizzly bear, porcupine, mice, voles, shrews, squirrels, hares and rabbits.
