Black ash has a large natural area in the United States and Canada. It is one among the last trees to leaf out in the spring and among the first to turn yellow and drop leaves in the autumn. These trees thrive in damp environments and are typically found in northern marshy forests.

The Emerald ash borer is threatening black ash throughout its range. This tree species is presently listed as endangered in Ontario. Read the recovery strategy to learn more about how we are protecting the black ash.
