Expanding Cattails and Shrinking Sedge Meadows: Reversible? — Biologically diverse sedge meadows in Great Lakes coastal wetlands are being overrun by aggressive cattails. This University of Wisconsin Sea Grant Institute project is evaluating the resilience of sedge meadows to this invasion and developing options for protecting and restoring these plant communities. >>

Managing a Pungent Problem — A pesky summer visitor has shown up on Wisconsin’s Lake Michigan shorelines the past six years. It’s Cladophora, an algae that drives off beachgoers with a pungent, stinky stench as it decays in massive heaps along the shore. Cladophora can exacerbate beach closings because it often harbors large numbers of Escherichia coli bacteria. Gulls like to eat the zebra mussels and other fauna snared by the algal mats, and gull fecal matter is loaded with the bacteria. >>

Beach Closings—Blame It on the Birds? — Some beachgoers are running into signs signaling closed beaches due to unsafe swimming conditions. One success story is a UW Sea Grant study of Bradford Beach, Milwaukee’s most frequently closed beach in 2004. Much of the E. coli came from seven stormwater outfalls scattered along the beach, as well as flocks of gulls that congregate along the shore. These findings resulted in a joint effort to map the stormwater system and develop a proposal to relocate the outfalls away from Bradford Beach. >>
