River to River CWMA
|
The River to River Cooperative Weed Management Area (CWMA) is a partnership between 12 federal and state agencies, organizations, and universities aimed at coordinating efforts and programs for addressing the threat of invasive plants in Southern Illinois. The CWMA was formally established in 2006 (view our MOU) and addresses both terrestrial and aquatic invasive plant species through collaborative projects and activities focused in Education / Public Awareness, Early Detection and Rapid Response, Prevention, Control and Management, and Research. The CWMA is grant funded and projects-based. Our goal is to cooperatively address the short and long-term effects of non-native invasive plants across jurisdictional boundaries within the 11 southern counties of Illinois. |
