US and Canadian Researchers Team Up to Prevent Spread of Oak-Killing Disease
An idea assistant professor Tara Bal (CFRES) proposed over dinner with a Canadian colleague has become a binational project exploring environmental factors that affect the northward expansion of oak wilt, a fatal tree disease spread by sap beetles.
Oak wilt, currently found in 24 states, can decimate both forest and urban plantings. The fungal disease kills otherwise healthy trees. In addition to landscape blight, it impacts wildlife habitat as well as the timber industry. The northern limit of the disease reaches the 46th parallel in Michigan, Wisconsin and Minnesota. The line hasn't moved much since it was observed in the 1980s, but climate change is expected to impact the environmental conditions in years to come. Project collaborators are particularly concerned about the establishment of oak wilt along the U.S.-Canada border and into Canada.
