Michigan environmental officials announced they have recently confirmed the presence of an invasive aquatic plant in at least four lakes. European frog-bit was first detected in southeast Michigan in 1996 and has since spread along the coastal areas of lakes Erie and Huron up to the eastern Upper Peninsula. Aquatic invasive species have the potential to harm Michigans environment, economy and human health. While waterfowl, currents and stream flow can spread the plant and its seeds, European frog-bit, like most invasive species, travels farther and faster by human movement. Reports also can be made to EGLEs Aquatic Invasive Species Program by email to EGLE-WRD-ANC@michigan.gov or by calling 517-284-5593.
