News and Updates

ISN Giveaway - Through September!

ISN and partner boot brush stations have a new addition - QR codes! If you spot one (or more) this summer, give it a scan and take our short survey. Your answers will help us learn who uses the stations, how often, and where more should be placed. 

Individuals who submit surveys will be entered into a drawing to win ISN swag. There will be first, second, and third prizes. The giveaway will remain open until Thursday, September 23, 2021. Winners will be selected at random and notified the following week. 

To learn more about boot brushes, where they're located, and to see a breakdown of the prize packages, follow this link. 

Japanese Barberry Trade-up Days

Registration for this year's Japanese Barberry Trade-up Day events is now open. Hosted at the Boardman River Nature Center and the Manistee Conservation District, pre-registered individuals can bring in their removed barberry shrubs to be disposed of correctly. In exchange, they will be given a coupon to a local nursery that participates in ISN's Go Beyond Beauty  program.

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.
