What it looks like

A smaller tree with a narrow crown, it has light grey bark that is soft and cork-like when young, becoming scaly with age. Oval leaflets on a central stalk are deep green and hairless. Full leaves, as opposed to single leaflets, tend to drop in the fall.

Where it is found

The black ash grows everywhere in Ontario except the Far North. It is one of the last trees to leaf in the spring, and among the first to turn yellow and drop leaves in the fall.

These trees love moisture, and are commonly found in northern swampy woodlands, from eastern Manitoba, throughout Ontario, and as far east as Newfoundland. The Emerald Ash Borer is currently threatening the species across its entire range.
