The Lake St. Clair (LSC) Cooperative Invasive Species Management Area (CISMA) was established in 2015. Today the partnership consists of over 24 partners of local governments, county government, non-profit organizations, and universities. The LSC CISMA operates within Macomb and St. Clair Counties. We are focused on managing the spread of five priority invasive species including: invasive Phragmites, black swallow-wort, Japanese knotweed, European frogbit, and flowering rush. The LSC CISMA also acts as a clearinghouse for all invasive species information, including identification, best management practices, and information on how to reduce to spread of 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 alter nutrient cycles.

Six Rivers Land Conservancy became the fiduciary for the Oakland County and Lake St. Clair CISMAs in 2018. Six Rivers sees managing invasive species as a key component of stewardship, which is a core part of their mission.
