Hemlock Woolly Adelgid
2019/2020 Winter Survey Information

This winter ISN is continuing to survey for hemlock woolly adelgid (HWA) in Benzie, Grand Traverse, Leelanau, and Manistee counties. While the previous winter focused on public land and easier-to-access properties, like conservation easements, the upcoming season will find our attention shifting to private property - but we need your help! Visit our HWA page to see what parameters we are seeking when identifying parcels to survey and if you qualify for a  site visit OR to fill out the landowner survey form.
