Volunteers are needed to remove invasive plants that threaten native habitats during stewardship workdays, taking place at several state parks in southern Michigan throughout July.

Workdays are an enjoyable way to spend time outdoors while restoring Michigan's ecosystems and learning about its inhabitants.

Workday details (including meeting locations, the stewardship volunteer registration form and links to individual park maps and directions) are available on the DNR website at Michigan.gov/DNRVolunteers. Volunteers are asked to register either by using the form or by emailing freih@michigan.gov.
