Acer glabrum, commonly known as the Rocky Mountain maple, is a species of maple native to western North America. It is a small, deciduous tree or large shrub that is part of the Sapindaceae family.

Description

Acer glabrum typically grows to a height of 3 to 10 meters, although it can occasionally reach up to 12 meters. The bark is smooth and grayish-brown, while the twigs are slender and reddish-brown. The leaves are opposite, simple, and palmately lobed with three to five lobes. They are 3 to 10 cm long and wide, with serrated margins.

The flowers of Acer glabrum are small, yellowish-green, and appear in clusters in the spring. The fruit is a paired samara, with each seed having a wing that is 2 to 3 cm long.

Distribution and Habitat

Acer glabrum is found in a variety of habitats, including montane and subalpine regions. It is commonly found in riparian zones, canyons, and mountain slopes. The species is distributed across western North America, from Alaska and British Columbia south to California and New Mexico.

Ecology

Acer glabrum plays an important role in its ecosystem. It provides food and habitat for various wildlife species. The leaves and twigs are browsed by deer and elk, while the seeds are consumed by birds and small mammals.

The tree is also important for soil stabilization in riparian areas, helping to prevent erosion with its root system.

Uses

Historically, Acer glabrum has been used by indigenous peoples for various purposes. The wood is light and was used for making tools and implements. The inner bark was sometimes used as a food source in times of scarcity.

In modern times, Acer glabrum is occasionally used in landscaping for its attractive foliage and adaptability to different soil types.
