Butternut

Butternut is threatened across its range by a canker fungus. The species has all but disappeared in many parts of the U.S.A. and is listed as endangered in Ontario, Quebec, and New Brunswick.

Several other Ontario tree species are threatened by exotic species, and conserving as much of their genetic diversity as possible is key to their future in our forests.
