No Emerald Ash Borer in district

The death of some ash trees in town is not due to the presence of the Emerald Ash Borer, a common pest in some parts of the United States.
“No. We’re watching for that,” noted Lincoln Rowlinson, forest health technician for the Ministry of Natural Resources.
“We can’t really pinpoint why the ash are dying,” he said.
Though the exact cause has not been positively identified, Rowlinson did suggest a few possible causes.
“Ash are very sensitive to drought going into the winter,” he noted.
With the dry summer here last year, many of them could have died during the winter.
Also, there are three kinds of ash in the area: white, green, and black.
“The white is on its northern limit here,” Rowlinson explained. “They’re almost outside of where they should be living.”
As a result, they would be “very susceptible to any stress,” he noted.
A lot of the larger ash trees around town tend to be white, he added.
The MNR remains on the lookout for the Emerald Ash Borer, a highly destructive insect from Asia whose larvae can interfere with a tree’s ability to transport water and nutrients.
The beetle has been found in parts of Michigan, Ohio, Illinois, Indiana, and Southwestern Ontario, and has killed more than 20 million ash trees, most in southeastern Michigan.
