The Lake Erie Cooperative Weed Management Area (CWMA) was established in 2009 and has completed over 7,000 acres of invasive species treatment on the properties of nearly 200 program participants throughout Ottawa, Lucas, and Sandusky counties. This area contains vital habitat for migrating birds and sensitive vegetation.

In 2009, Winous Point Marsh Conservancy partnered with the U.S. Fish and Wildlife Service’s Private Lands Program to develop a non-native Phragmites australis control program for Western Lake Erie. A total of nine private landowners partnered to provide seed funding for grant applications that resulted in nearly $50,000 dollars in funding, including a $20,000 donation of herbicide from DOW AgriSciences.  The initial funding was used to hire a helicopter to aerially treat 550 acres of non-native Phragmites in the Sandusky Bay and Lake Erie marshes region. Funding from the U.S. Fish and Wildlife Service was secured to provide follow-up treatment on these lands in 2010. Additionally, in 2010 the partnership expanded to include The Nature Conservancy and the CWMA applied for $500,000 in federal grant funding to expand and continue the management program.
