Butternut Monitoring and Conservation Program
The butternut tree (Juglans cinerea) is a nut-bearing tree that grows in eastern North America. The butternut is in danger of disappearing due to a fungal disease commonly called butternut canker (Sirococcus clavigignenti-juglandacearum). The fungus can infect and kill healthy trees of all ages and sizes as well as stressed or injured trees. The disease has been found in ninety percent of the examined butternuts in Ontario.

Landowners have been critical in the butternut monitoring and recovery program. If you think you have a butternut tree on your property, and would like to get involved in the recovery efforts, please contact the appropriate Stewardship Coordinator or representative that can be found in Simcoe, Dufferin County, York, Halton, Peel Region or contact the Forest Gene Conservation Association for other parts of southern Ontario.
