Sweet Birch

Betula lenta • Cherry birch

Native

Sweet birch is a medium sized tree, typically growing up to 20 meters tall. It is native to North America and is widespread in the United States, however it is considered a endangered species in Ontario. All sweet birch trees in Ontario (only about 50 mature trees) are located near the shore of Lake Ontario. It is found on moist, well-drained clay loam soil over limestone bedrock. Historically, the main threat to Cherry Birch has been habitat destruction. Development and forest clearing in southern Ontario has caused a decline in suitable habitat for this species.
