Black Ash

Scientific name

Fraxinus nigra


The Black Ash is a small deciduous tree growing about 20m in height, which naturally occurs in swampy areas of woodlands and damp shorelines. This species produces a slender trunk with a narrow, open crown and ascending branches. Leaves are dark green, sharply toothed, and compound with 7-11 leaflets. Wood produced by the Black Ash can be bent making it popular for snowshoe frame and canoe rib construction. The Black Ash is widely established across Canada, but is threatened by the invasive insect, Emerald Ash Borer.
