Acer glabrum

Acer glabrum is a species of maple tree native to western North America, from Alaska, through western Canada, to California and New Mexico in the United States. It is commonly known as rock maple or Douglas maple.

Description

The Acer glabrum is a small tree or large shrub that grows to 10 meters (33 ft) high. Its leaves are 2 to 10 cm (0.79 to 3.94 in) long and broad, with three or five lobes, and are green on top and paler beneath. The flowers are produced in corymbs of five to ten, yellow to greenish, with five sepals and petals. The fruit is a samara or winged seed.

Distribution and habitat

Acer glabrum is found in a variety of habitats, from lowland dry areas to moist mountainous regions. It is often found in association with other tree species such as quaking aspen and lodgepole pine. It is tolerant of a wide range of soil types, but prefers well-drained soils.

Uses

The wood of the Acer glabrum is hard and close-grained, and has been used for tool handles and other small items. The tree is also used for ornamental purposes in landscaping due to its attractive form and foliage.

Conservation

While Acer glabrum is not currently considered threatened, it is susceptible to a number of pests and diseases, including verticillium wilt and powdery mildew. Conservation efforts are focused on maintaining healthy populations and protecting habitat.
