Native prairie restoration fights invasive species and helps the endangered ones (Great Lakes Echo): From flower pots to 100-acre lots, planting native prairie plants is increasingly important as they face threats from invasive species and human development. Prairies in the Great Lakes region are known for hosting bobolinks, wild turkeys, butterflies and a vast array of wildflowers. A program was created to collect seeds from native plants to promote prairie growth and engage volunteers with the environment. It’s something that everyone can help with.
Researchers creating warning system for low oxygen water (Great Lakes Echo): Researchers are developing a system to warn water managers when unpalatable, harmful water from Lake Erie is headed their way. The project, with $1.5 million in federal funding, could give water treatment plant operators time to prepare to treat water that is hypoxic by predicting the movement of oxygen-depleted Lake Erie water. Hypoxia occurs when dissolved oxygen in a body of water is depleted to a level that is harmful to aquatic organisms. This is a particular problem in the central basin of Lake Erie, where it’s deeper.
Mini-tsunamis a hazard in the Great Lakes (Great Lakes Echo): The Great Lakes have their own miniature version of tsunamis – more than 100 times per year. That’s according to new research led by the University of Wisconsin Madison. The name of these waves – and the danger that comes with them – are relatively unknown to those in the region. Their name, meteotsunami, is a contraction – broken down, it means meteorological tsunami. They’re about a foot high. And they’re not caused by earthquakes like actual tsunamis. Researchers are now looking into a way to predict when these mini-tsunamis might occur in order to warn beachgoers. According to the study, Lake Michigan is most prone to these mini-tsunamis, followed by Lake Erie and Lake Huron.
Michigan Dune Alliance helps protect Michigan’s iconic sand dunes from invasive species (Model D): From the towering glory of Sleeping Bear Dunes to more modest southern Lake Michigan beaches, perhaps nothing in our state represents “Pure Michigan” better than our iconic sand dunes. But as with so many of Michigan’s fragile native ecosystems, invasive weeds threaten to strangle the dunes. Exotic fungi and invasive bugs are killing the trees that are part of the dune ecosystem, while invasive water plants are choking coastal marshes and interdunal wetlands. There are around 550 miles of coastline on the Mitten’s west that are under siege from alien invaders. Luckily, the combined forces of the Michigan Dune Alliance are on a search-and-destroy mission throughout that long stretch of sand.
