'One of the world's most invasive aquatic plants' found for first time in Michigan

(Detroit Free Press) Hydrilla, called "one of the world's most invasive aquatic plants," by Michigan Department of Environment, Great Lakes and Energy (EGLE) officials, has been found for the first time in Michigan waterways.

Two small populations of the plant were confirmed in adjacent, private ponds on residential properties in Berrien Springs in southwest Michigan, EGLE officials reported Monday. The aquatic invader was discovered during routine monitoring following up on treatment of the ponds for another invasive plant, parrot feather, which was found there in 2020.

Hydrilla has several ways of reproducing − root tubers, buds, and even small plant fragments can develop into new plants. That means it can spread through a body of water quickly, outcompete native plants, and quickly form dense, single-species infestations.

It's not clear how either parrot feather or hydrilla made their way into the ponds. Both species are prohibited in Michigan and are unlawful to sell, possess, and import. Before their confirmed arrival, both species were on Michigan's invasive species watch list due to their potential environmental threat. .................(more)

"Two years ago, the cove was a magnet for anglers, a clear pond from which Selden Creek runs south through sunken meadows of wild rice and drowned oaks to join the river at the bottom of Selden Neck.

Now you can’t sink a hook in the cove. It c be difficult even to push a boat through. It is choked from its sandy bottom to the water’s surface by an acre-sized mat of a ferocious aquatic weed called hydrilla."

Good luck with that shit,
