Contaminated oak tree from DNR bulletin

The DNR is partnering with the US Forest Service to treat Michigan’s forests effected by an exotic and largely invisible killer: oak wilt. This deadly fungus can kill healthy trees within weeks by interfering with the vessels that transport water throughout the tree, putting Michigan’s state parks and recreational areas at the highest risk.  The fungus is transported by sap-feeding beetles, or “picnic beetles,”so the public is being urged not to move firewood or prune oak trees between April 15 and July 15, when these beetles feed on the tree sap.
