Presented by Mike Greer, USACE Buffalo, and
Katie Evans, Ecology and Environment, Inc.
The webinar provides an introduction to the Great Lakes Hydrilla Collaborative, including information about the purpose of and need for the Collaborative, background information on hydrilla, and the importance of the needs assessment survey to identify issues of greatest need and to inform the content of the website and webinar series.
Presented by Dr. Mark Heilman, SePRO Corporation
This webinar provides an overview of aquatic herbicides used for management of monoecious hydrilla, including those used for short-term and long-term control, along with associated project examples. The webinar also includes a summary of hydrilla management strategies based on site characteristics, and conclusions related to the future outlook for the management of this species.
Presented by Dr. Rob Richardson, North Carolina State University
This webinar provides an overview of the biology of monoecious hydrilla, including differences in biological features between monoecious and dioecious hydrilla. Additionally, the webinar also includes a summary of a series of research questions that influence hydrilla management decisions.
Presented by Mark Warman, Cleveland Metroparks
This webinar provides a case study on Cleveland Metroparks’ early detection, control, and prevention efforts at several sites in Northeast Ohio. The webinar also includes a discussion of herbicide treatment in hydrologically-dynamic waterbodies, evidence to halt treatment and monitoring, and the effort to build a regional surveillance network.
Presented by Chris Doyle, SOLitude Lake Management
This webinar provides a discussion of the general approach to hydrilla monitoring, and also provides details on the specific approaches developed for three distinct sites: the Hudson River and New Croton Reservoir in New York, and the Delaware and Raritan Canal in New Jersey.
Presented by Stacie Hall, Assistant Manager for Pymatuning State Park with the Pennsylvania Department of Conservation and Natural Resources, and Cathy McGlynn, Aquatic Invasive Species Coordinator with the New York Department of Environmental Conservation
This webinar provides a discussion of invasive species check stations targeting boater outreach at Pymatuning State Park and other hydrilla outreach efforts for the reservoir, and the comprehensive communication strategy developed to communicate with stakeholders for the Croton River Hydrilla Control Project.

Presented by Kris Erickson, Ecology and Environment; Dr. Matt Barnes, Texas Tech University; and Kristen Hebebrand, Chagrin River Watershed Partners
This webinar provides the framework and an overview of the risk assessment, including the distribution modeling used to support determinations of suitable habitat for hydrilla; the dispersal modeling used to understand the pathways by which hydrlla could potentially spread; environmental, economic, and social/cultural impacts; characterization of risk (i.e., where are the most vulnerable areas); and risk management recommendations and BMPs.
