Hemlock Woolly Adelgid

UPDATE (4.20.2021): We recommend that all surveying efforts are stopped for the season as HWA crawlers will soon be active again. It can resume in the winter 2021/2022 season. Please contact ISN with any questions. 

Hemlock woolly adelgid (HWA) was recently confirmed in northern Benzie County, within ISN's service area. Survey efforts are being expanded and we are working with partners to address this issue. Please read the complete press release here. 

For more information on HWA, ISN's work to stay ahead of the spread, and surveying information, please follow the link below.
