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 for Macomb and St. Clair counties?

The LSC CISMA prioritizes outreach, education, and management of certain invasive species with high potential for negative impacts in the region. These include: invasive Phragmites, Japanese and giant knotweeds, European frog bit, red swamp crayfish, water lettuce and water hyacinth. The CISMA is also on high alert for all state watch list species like spotted lanternfly and Asian longhorned beetle.

Catch us at our next event!

Join the Lake St. Clair CISMA, St. Clair County Parks, and MSU Extension for our next boat wash event hosted at the North Channel DNR Boat Launch!

Staff will be providing information on aquatic invasive species (such as European Frog-bit, Water Primrose, Hydrilla, and others) and ways to reduce their spread, while also offering a free boat wash to further prevent the spread of these invasives!
