Bigtooth aspen

Bigtooth Aspen (Populus grandidentata) is a deciduous tree species native to eastern North America. It is a member of the Salicaceae family and is commonly known for its large, coarse teeth, which give the tree its name.

Description

The Bigtooth Aspen is a medium-sized tree that typically grows to a height of 20–30 m. The bark is smooth and greenish-white, becoming gray and furrowed with age. The leaves are alternate, simple, 6–10 cm long and broad, with large, coarse teeth along the margin. The flowers are catkins, produced in early spring before the leaves emerge. The fruit is a small capsule containing numerous tiny seeds.

Distribution and Habitat

The Bigtooth Aspen is native to eastern North America, from Newfoundland west to Manitoba and Minnesota, and south to Virginia and Missouri. It is typically found in upland areas and dry soils, but can also grow in a variety of other habitats.

Ecology

The Bigtooth Aspen is a pioneer species, often colonizing disturbed areas such as burned-over lands or cleared fields. It is a fast-growing tree, but has a relatively short lifespan. The tree provides habitat and food for a variety of wildlife species, including birds, mammals, and insects.

Uses

The wood of the Bigtooth Aspen is light, soft, and weak, but it is commercially important for pulpwood and is also used for making pallets, crates, and other low-grade lumber products. The tree is also planted for ornamental purposes and for soil stabilization.
