Many invasive species are already in Michigan, causing harm to the state’s waters, woods and open spaces – and others could be on the way. What is being done to respond to these threats?

NotMISpecies webinar bannerNotMISpecies, a new, monthly webinar series from Michigan’s Invasive Species Program, will take an in-depth look at efforts across the state to prevent the introduction and spread of invasive plants, insects, animals and diseases.

Michigan’s Invasive Species Program, a collaborative effort of the departments of Natural Resources; Environment, Great Lakes, and Energy; and Agriculture and Rural Development, coordinates and supports invasive species initiatives across the state and provides support through the Michigan Invasive Species Grant Program.

Topics include species-specific actions such as those underway to control red swamp crayfish; innovations in research and technology, like those being used to respond to grass carp in Lake Erie; and programs designed to help communities prevent and manage harmful invasive species.

“We’re excited to be able to showcase the work that’s happening behind the scenes, including the collaboration and resource sharing between agencies, researchers, businesses and local communities,” said Joanne Foreman, DNR invasive species communications coordinator. “There are no simple, ready-made solutions for keeping invasive species out of the state or eliminating those that are here, but Michigan remains at the forefront of many national and bi-national efforts to find sound solutions.”

They will share what they are learning about how species behave outside their native environments and how this knowledge helps to prevent or control infestations. A question and answer period will follow each presentation.

The series kicks off at 9 a.m. Thursday, Oct. 22 with a look at how science and technology are fueling a multi-jurisdictional response to grass carp in Lake Erie.

“Delicious but Dangerous,” at 9 a.m. Nov. 17, examines the hazards caused by thousands of burrowing invasive red swamp crayfish and how this species’ habits complicate removal efforts.

The series takes a break for the holidays and returns Jan. 22, 2021, with “Hemlock Rescue,” a look at the labor-intensive effort to inventory and treat eastern hemlock trees infested with hemlock woolly adelgid. Topics for future sessions will be added throughout the year.

Each webinar will be presented live, with recordings available for viewing approximately one week after the live event. For more information on each NotMISpecies webinar, including registration links, visit

Michigan's Invasive Species Program is cooperatively implemented by the Department of Environment, Great Lakes, and Energy, the Department of Natural Resources, and the Department of Agriculture and Rural Development.
