Oakland County Cooperative Invasive Species Management Area

The Oakland County Cooperative Invasive Species Management Area (CISMA) was established in December 2014 by 19 partners. Today the partnership consists of over 30 members of local governments, county government, non-profit organizations, and universities. We are focused on managing the spread of eight state-priority invasive species including: invasive Phragmites, black and pale swallow-worts, Japanese knotweed, European frogbit, flowering rush, red swamp crayfish and New Zealand mud snails. Members also have extensive experience managing other common invasive plants such as buckthorn, garlic mustard, oriental bittersweet and purple loosestrife.

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 human health. In Oakland County, invasive species reduce property values, damage infrastructure, create public safety hazards and degrade natural areas.

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.
