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.
