Trembling Aspen – Populus tremuloides

General: Medium-sized tree, smooth whitish-green bark with black spots. Bark can become rough at the bottom of the tree, similar to Balsam Poplar but it won’t continue like that all the way to the top. Buds are not sticky or smelly.

Leaves: Roundish with a short pointy tip, similar in shape to a garlic bulb. Leaves are green on top and a slightly lighter green underneath. Leaf stem is flattened which makes the leaves ‘tremble’ in the wind.

Flowers: Drooping catkins that appear before the leaves in spring.

Reclamation Notes: Occurs on almost every soil type but grows best in well-drained sandy or loamy soils with medium moisture. Aspen will not tolerate soils that are saturated for a long period of time. A pioneer species, Aspen likes full sun and regenerates primarily through suckering (new shoots from the roots of parent trees). Aspen can act as a ‘nurse’ tree, shading softwood species like White Spruce.

Used primarily in pulp/paper production and OSB (oriented strand board) production by the forest industry.
