Dominating much of our marshland around the Great Lakes is the exotic Purple Loosestrife, Lythrum salicaria. It blankets areas in solid patches, not allowing room for any native species to flourish. Unless you're manipulating water levels, burning, mowing and herbicide won't work. Several species of beetles have been introduced to feed on the plants, but the best way to control it is to get down to the roots and pull them out. Once restricted to northern Ohio, I have seen it down here in Athens County, and clear over in Cincinnati. It is said a large plant can produce 2 million seeds a year, so you can see why we have our work cut out for us.
