Board and Staff | Current Members | Frequently Asked Questions

We are a collaboration to support functioning ecosystems and
enhance quality of life through invasive species management.

The Oakland County Cooperative Invasive Species Management Area (CISMA) was established in December 2014 by 19 partners. Today the partnership has grown to over 40 members including local governments, county governments, non-profit organizations, and universities. Check out our current members [here].

We are focused on managing the spread of eight priority invasive species including: invasive Phragmites (common reed), Black and Pale Swallow-worts, Knotweeds, European frog-bit, Flowering rush and Red swamp crayfish. Members also have extensive experience managing other common invasive plants such as Buckthorns, Autumn olive, Garlic mustard, Asian bittersweet, and Purple loosestrife. You can learn more about all these species through our invasive species profiles in the menu, or clicking on the name of each species listed above.
