The vegetation spatial database coverage (vegetation map) is a product of the Effigy Mounds National Monument Vegetation Mapping Project, USGS-NPS Vegetation Mapping Program (VMP). The U.S. Geological Survey (USGS) Upper Midwest Environmental Sciences Center (UMESC) in La Crosse, Wisconsin, and the Minneapolis Office of NatureServe in Minneapolis, Minnesota, have completed mapping and classification of existing plant communities of Effigy Mounds National Monument (EFMO) and extended surroundings. Photointerpreters, ecologists, and botanists collaborated to describe National Vegetation Classification System (NVCS) plant communities (associations) and determine how best to map them using aerial photographs. --- Two...
The 25-mile stretch of the Yellow River adjacent to the Necedah National Wildlife Refuge in Central Wisconsin provides valuable habitat to numerous species of concern including the Red-shouldered hawk (Buteo lineatus), the Cerulean warbler (Dendroica cerulea), the Eastern massasaugua rattlesnake (Sistrurus catenatus), and the Karner blue butterfly (Lycaeides melissa samuelis). Since very little data exist regarding the location and composition of these habitats, a detailed land cover/land use (LCU) map is needed to better define and more effectively manage these areas of concern.

An ecological study on mercury contamination in the wetland of West Dongting Lake in China. This study measured the total mercury concentration in the soil and compared it to the measured total concentration of mercury in the above and below ground tissue of different plant species on the floodplain of West Dongting Lake. Bioconcentration, bioaccumulation, and translocation factors were determined for each plant species at the nine study sites. Soil data on mercury concentration as well as moisture and bulk density was collected. Measurements of species richness, evenness and biodiversity were also calculated.
