Butternut trees typically grow in low numbers, scattered throughout forests. These trees were never abundant in Ontario.
What are the primary threats to this species?
Land clearing was initially a primary threat to butternuts. In recent years, the butternut canker has been infecting and killing trees. The butternut canker was introduced to Ontario in the early 1990s. Infected trees die within a few years.
What is being done to help protect this species?
The Forest Gene Conservation Association has been recording occurrences of healthy butternut trees in order to develop conservation strategies and locate disease resistant trees for scientific study.
