Fig. 2. Relative losses in water quality protection since the 1800s due to wetland destruction and degradation in the three watersheds that compose the Duck-Pensaukee Basin, Wisconsin. Each color-ramp represents one of three watersheds in the basin. Results are reported by sub-watershed, with darker shades indicating greater losses. Maps were also created for losses in surface water supply, flood abatement, and carbon sequestration. Map from Miller et al. (2012) using data from The Nature Conservancy, U.S. Fish and Wildlife Service, Wisconsin Department of Natural Resources, ESRI, and other partners.
