Plain Language Summary
Butternut (Juglans cinerea) was listed by the Canadian Species At Risk Act as endangered in 2003 due to an introduced fungus that causes multiple wounds in the crown, trunk and roots of the tree, eventually killing the tree. The fungus kills butternut trees of all sizes and ages and to date there are no controls for this disease and some evidence suggests that there might be genetic resistance to this disease.
