Non-native Forest Pests
Non-native insects and diseases are having a significant impact on the forests of Sleeping Bear Dunes. Insects such as emerald ash borer, Asian long horned beetle, hemlock woolly adelgid, sirex wood wasp and gypsy moth can cause mass devastation.

Some of these insects and diseases are already within Lakeshore boundaries while others are knocking on our door.
