Manitoba Maple

Photo of the Tree

The Manitoba maple occurs in the eastern United States and a few western locations. It is also found in southern Saskatchewan and Manitoba. This small tree grows to about 66 feet high (20 metres), and has an estimated life span of 150 years.

This maple species is unusual in that it has leaves resembling ash leaves, yet produces key-like fruits like the maples. For this reason, it is sometimes called the ashleaf maple.

Its leaves consist of five to nine leaflets. Its branches are weak and release an offensive odour, when broken.

Its gray fruit has large wings. The seeds remain on the tree over winter, and are an important source of winter food for birds and mammals.

This maple survives on most soils, and is found on sites that are seasonally flooded, as well as along lake shores and stream banks.

It is planted as an ornamental or windbreak in Canadian prairie provinces. In 1760, it was introduced in France by the Count of Galissonnière. It is often called érable à Giguère, in French, no doubt a deformation of the name érable argilière which the French in Illinois used in 1814.
