Lake St. Clair

Cooperative Invasive Species Management Area

The Lake St. Clair Cooperative Invasive Species Management Area is a collaborative effort to enhance ecosystem functions and enrich ecosystem services through invasive species prevention, detection, management, and outreach in Macomb and St. Clair counties of Michigan.

What are invasive species?

Invasive species are organisms that are not native and whose introduction causes harm, or is likely to cause harm to Michigan’s economy, environment, wildlife, and/ or human health. Economic impacts of invasive species include reduced property values, degradation of infrastructure, public safety hazards, and loss of land use. Environmental impacts of invasive species include loss of biodiversity, loss of habitat, and altered nutrient cycles, hydrology, and topographies.

Which species are priorities?

The Lake St. Clair Cooperative Invasive Species Management Area (LSC CISMA) prioritizes outreach, education, and management of certain invasive species with high potential for negative impacts. These include: invasive Phragmites, Black Swallow-wort, Pale Swallow-wort, Japanese knotweed, Giant knotweed, European frog bit, and Flowering rush. The CISMA is also on high alert for state watch list species like Spotted Lanternfly, Red Swamp Crayfish, and Water Lettuce.
