What's New?

Please join us on September 25th at 2 pm EST for the next webinar in our technical webinar series, "A Hydrilla Project in Ohio's Lake Erie Basin: Detection, Control and Prevention."
Mark Warman, Hydrilla Project Coordinator for the Cleveland Metroparks, will provide a case study on Cleveland Metroparks’ early detection, control, and prevention efforts at several sites in Northeast Ohio. The webinar will also include a discussion of herbicide treatment in hydrologically-dynamic waterbodies, evidence to halt treatment and monitoring, and the effort to build a regional surveillance network.
