LELAND â Northwest Lower Michiganâs national park proved a fruitful natural laboratory for an invasive species study.
Scientists recently reported pronounced reductions in both cladophora algae and quagga mussel density in Lake Michiganâs offshore waters near Sleeping Bear Dunes National Lakeshore after an underwater project by the Invasive Mussel Collaborative. An offshore fish-spawning reef was the experimental zone in Good Harbor Bay.
So Great, So Fragile: Great Lakes, Lake Michigan health depend on keeping invasive species out

CHICAGO (WLS) On the surface of Lake Michigan, glistening water rushes over sandy beaches. But underneath the waves is a fragile ecosystem that interconnects a complex food web critical to the overall health of the Great Lakes.
Disruption to that system can have dire consequences to its inhabitants, and that means paying attention not only to what is living in the water but on keeping unwelcome predators out. So one of the things that we know about invasive species is that they, they tend to get into an ecosystem, such as the Great Lakes. And they, they wreak havoc, said Jeffrey Zuercher, project manager at the US Army Corps of Engineers Chicago District. It causes a lot of damage to the ecosystem, things that we don t want to have happen over time. And we want to make sure that they stay o

ANN ARBOR, MICH. A project aimed at reducing the number of invasive quagga mussels in Lake Michigan near Sleeping Bear Dunes National Lakeshore has proved successful, providing important takeaways for groups involved in the ongoing effort to combat Great Lakes invasive species.
The project used a molluscicide consisting of dead cells from
Pseudomonas fluorescens bacteria last August on a reef within Sleeping Bear’s Good Harbor Bay, an important habitat for native fish that is currently jeopardized by invasive species, algae growth, and the botulism toxin.
