Forest owners and land managers should look for beech leaf disease (BLD), a destructive beech tree disease in the United States, this summer.
Although it has not yet been found in Wisconsin, recent discoveries of the disease in Michigan and other nearby states highlight the continued importance of monitoring BLD’s expansion. There is potential for BLD to move into Wisconsin, as the eastern portion of the state overlaps with the native range of American beech.
