Quaking Aspen – Populus tremuloides – native
Pictured here is a very young Quaking Aspen, but at maturity, it transforms into a 35-59 foot-tall tree. The wood has many uses, including its development into pulpwood and boxes while the tree bark and foliage are consumed by numerous mammals such as deer, beavers and sheep. Aspen trees generally grow in groves, connected by a system of underground roots. They are prone to diseases and are often deeply affected by insect pests, fungal infections and drought.
