A new website can help you identify potentially invasive plants in your backyard in Michigan. Across the eight Great Lakes states and Ontario, 28 woody plant species are regulated as invasive by at least one jurisdiction. Multiflora rose, black locust, Tatarian honeysuckle and glossy buckthorn are just some of the woody invasive species found in Michigan. Now these plants pose a serious threat to natural areas in the Great Lakes region, outcompeting native plants and damaging wildlife habitat. The Woody Invasives of the Great Lakes Collaborative is one of several regional invasive species initiatives supported by the Great Lakes Restoration Initiative.
