Quaking aspens are the most widely distributed tree species in North America. They grow in Alaska and Canada, all the way south to Mexico. They withstand such a wide range of climatic conditions by growing at lower altitudes in the north and higher altitudes in the south.
Where are quaking aspen found?
Quaking aspen can be found from Alaska to Mexico and from Vancouver to Maine (Jones et al. 1985; Mitton & Grant 1996). In the north-central part of the continent, quaking aspen occurs at almost any elevation, while in the southern part of the US and in Mexico, it tends to be found only at higher elevations.
Where do aspen trees grow in the US?
Most of the aspen forest in the United States is found in Utah and Colorado, though it is also scattered throughout all of the western states.
