FROG-BIT INVASION – Lake Superior State University biologists pose with an armful of European frog-bit, an invasive water plant that is spreading into Raber Bay in Michigan's Upper Peninsula. An ongoing wetlands-monitoring project turned up the invader's presence this past summer. LSSU biology Prof. Ashley Moerke (left, rear) and students working as technicians with the Great Lakes Coastal Wetland Monitoring project joined Nick Cassel (back, right) - an LSSU alum and conservation district employee - on a survey expedition from Raber Bay Resort on August 4. Boaters can limit frog-bit's spread by merely pulling any weeds off of boat propellers. The plant, which has already made appearances around downstate Alpena and Tawas, has been spotted in the St. Mary's river Munuscong Bay, just north of Raber. Biologists hope public education, some strategic pulling, and a yet-to-be-determined herbicide might curb the plant's impact on the Great Lake region. Newly graduated fisheries and wildlife student Brian Curell (left) is lead research technician with the Great Lakes Coastal Wetland Monitoring project. Conservation biology senior Alexis Schefka (center) and fisheries/wildlife management junior Trevor Dunn (front, right) both work as technicians on the project. Schefka, who is also minoring in marine and freshwater science, is from Shelby Township, Mich.; Dunn is from Alpena, Mich. (LSSU/John Shibley)
