| Project Abstract: |
Indiana Dunes National Lakeshore (INDU) is located downwind of the Chic ago-Hammond-Gary area at the southern tip of Lake Michigan. Pollutants emanating from this area are routinely deposited on INDU by wet and dry atmospheric deposition. Pannes are small, nutrient limited, 1 to 4 acres, intra-dunal wetland/upland complexes that are isolated form surface flow by high dunes. Pannes are important because they provide habitat for many habitat-restricted plants, amphibian, reptile and dragonfly species. Seventeen state-listed plant species are found in pannes. Over the past 15 years, cattail, common reed and other invasive species have invaded pannes. In this study, mesocosm and field investigations will be conducted to determine the levels of heavy metals and nitrogen in pannes, their spatial distribution within a panne and the threshold levels necessary to increase susceptibility of panne vegetation tin invader species. |
