(Populus tremuloides)

Size at 100 years: 50-60 feet tall, 1-1 1/2 feet in diameter

Life Span: 120 years

Leaves: 1 1/2-3" in diameter, broadly egg-shaped, edge finely sawtoothed. Upper surface shiny green, dull green beneath turns brilliant gold in fall.

Fruit: About 1/4" long, narrowly conical, curved

Bark: Smooth, whitish and thin to cream-colored becoming dark brown or gray with age.

Where to find: Sandy or gravelly slopes at mid to low elevations, often found in pure stands sharing a single root system.

Things to know: Quaking aspen got its name from the leaves, which tremble in the slightest breeze because of their flat leaf stem. A "pioneer" tree after fires and in abandoned fields, it is short lived and often replaced by conifers. Used for matches, boxes, and particle board.
