Don’t flush that unwanted goldfish – find it a new home instead. Home aquariums and water gardening are two of the many routes invasive species take to enter Michigan habitats. A Michigan State University Extension program provides educational materials and resources for rehoming unwanted aquatic pets. Reduce Invasive Pet and Plant Escapes (RIPPLE) works with hobbyists, retailers and gardeners to minimize the release of invasive species into the wild. Most people may not give much thought to letting one or two pets go for a variety of reasons – financial, lifestyle changes or change of seasons, for example – but Paige Filice, the program’s primary coordinator, said those numbers add up.

Researchers are exploring new techniques to remove an invasive crayfish from Michigan waters. The Michigan Department of Natural Resources has been fighting an invasion of red swamp crayfish since they first appeared in the state in 2017. Aggressive attempts to trap and remove the crustacean haven’t worked. Kathleen Quebedeaux, a fisheries biologist with the DNR, said eradicating the invader will require a variety of approaches. “In order to have a more efficient means of achieving eradication, we need other tools in our toolbox,” she said.

Community input sought for cleaned-up lakes, shorelines

It’s taken over 30 years and $80 million to restore Muskegon Lake and a few nearby smaller bodies of water.

Decades of pollution and rapid urbanization created ecological problems so severe that the lake was designated a “Great Lakes Area of Concern” by the U.S. and Canada in 1987.

Look fast or you may miss an elusive 170-year-old sunken schooner off the coast of Baileys Harbor, Wisconsin.

The mostly intact shipwreck, which was added to the National Register of Historic Places in early April, isn’t always visible, even though it’s in very shallow waters, said Tamara Thomsen, a Wisconsin Historical Society maritime archaeologist.

The Mississippi River Basin and the Great Lakes-St. Lawrence River Basin supply freshwater and drain wastewater for millions of people.

Two of the largest watersheds in the U.S., they span state and political boundaries.
