Invasive plant that hinders boats, wildlife found in another Michigan county

An invasive aquatic plant, called European frog-bit, has been found in the lower Lincoln River in County Mason.

It has already been confirmed in several other places in the state and forms dense mats on the surface of slow-moving waters. These mats hamper the movement of boats and the movement of large fish and diving ducks, recent study finds Press release from the Michigan Department of the Environment, Great Lakes and Energy.

“Because invasive aquatic plants like the European frog bit are difficult and expensive to control, we remind boaters, waterfowl hunters and anglers to remove plants and debris from boats, trailers and gear. after each use to prevent the spread of this and other invasive species. Said Joanne Foreman, invasive species communications coordinator at the Michigan Department of Natural Resources.

The European frog bite was first detected in the southeastern state in 1996 and has since spread. In 2016, the plant was discovered in Reeds and Fisk Lakes in East Grand Rapids. More recently, it has been found in Jackson and Washtenaw counties and in Mackinac County. The most recent sample was found in Lincoln River last month.

The plant, which resembles a miniature water lily with quarter-sized leaves, floats freely. Unfortunately, this makes it easier to transport to new locations. Activities such as boating, waterfowl hunting, and fishing can unintentionally contribute to the spread of the invasive plant, as parts of the plant can attach themselves to equipment such as boats, trailers, and gear. , according to the press release.

“Frog-bit is spreading, so it’s good to get the word out. It might well be in the Lincoln River, but maybe not,” said Tom Alwin, aquatic biologist at the Department of the Environment, Major. Michigan Lakes and Energy. “We haven’t seen it much in the rivers. It might not form those big stacks, but it’s a stranger to us.”


Fortunately, the European frog bit is a fairly straightforward plant to identify, according to Alwin. This will make it easier for boaters, anglers and waterfowl hunters to make sure it is easier to clean the plant from any equipment they use to prevent spread to other bodies of water.

“We ask people to watch everything they use in the water, if they are fishing, check their fishing gear and if they are sailing, check their boat, to make sure they are removing any plant matter before they go. travel from one body of water to another. People should clean up any plant matter. It’s a good habit to take in any body of water you use, “Alwin said.

Below are some good practices to help prevent the spread of European walrus and other aquatic invasive species:

• Clean Up: Inspect boats, trailers, docks and gear and remove all mud, debris and plant matter. Use a hose or pressure washer when available. Dispose of unwanted materials in a trash can.
• Draining: Remove water from livewells, bait buckets, bilges and other compartments before leaving an access site.
• Dry: Let boats and their equipment dry for at least five days, if possible, before using them in other bodies of water.
