Populus grandidentata

Populus grandidentata, commonly known as the bigtooth aspen, is a deciduous tree species native to eastern North America. It belongs to the Salicaceae family and is part of the Populus genus, which includes other aspen and poplar species.

Description

The Populus grandidentata is characterized by its large, toothed leaves, which give the tree its common name. The leaves are typically 5-10 cm long and 4-8 cm wide, with 20-30 sharp, irregular teeth on each side. The bark of the tree is smooth and greenish-white, becoming darker and furrowed with age.

The tree typically grows to a height of 20-25 meters, with a trunk diameter of up to 60 cm. It has a fast growth rate and is often one of the first species to colonize disturbed areas, making it an important species in successional ecosystems.

Distribution and Habitat

Populus grandidentata is found throughout the eastern United States and Canada, from Newfoundland west to Minnesota, and south to Virginia and Missouri. It prefers well-drained, sandy or gravelly soils, and is often found in mixed hardwood forests, along streambanks, and on rocky slopes.

Uses

The wood of the Populus grandidentata is light, soft, and low in strength, making it unsuitable for most construction purposes. However, it is commonly used for pulpwood, and to a lesser extent for making crates, pallets, and veneer. The tree's fast growth rate and ability to colonize disturbed areas also make it useful for reforestation and erosion control efforts.

Conservation Status

While Populus grandidentata is not currently listed as threatened or endangered, it is subject to several threats, including habitat loss due to development, and diseases such as aspen canker and aspen decline.
