Beech bark disease has been killing American beech trees in eastern North America since the late 1890s. In northern New England, New York, and the Maritimes where the disease is most severe, groups of disease resistant trees occasionally occur. Genetic studies reveal that trees in groups are families, and distribution patterns suggest that they were “planted” by blue jays.
