In 2015 the DNR reported cases of Oak wilt in Leelanau and Grand Traverse Counties.
Please be on the lookout for this destructive disease and help us prevent the spread of oak wilt to the LLP. Oak wilt is a fungal disease that affects the northern red oak, black oak and pin oak trees. Infected trees usually die a couple of weeks after being infected and the disease spreads through the root systems to other trees within 100 feet of an infected tree. Beetles spread the disease as they move from tree to tree and it generally emerges in spring and summer.
- Do not injure or prune oaks from April 15 to July 15.
- Seal an injured wound on the tree with latex paint.
- Do not move suspected firewood from an infected oak.
- Cover firewood with a tarp right to the ground to keep beetles out and allow the heat to kill any suspected fungus
Go to the DNR website for more information and let us know if you find any oak wilt on your property.
