The Coastal Wetland and Tributary Decision Support Tool for the Duck-Pensaukee is an interactive, online map designed to help conservationists prioritize sites in the Duck-Pensaukee Watershed for land protection and restoration projects. The Duck-Pensaukee Watershed is a sub-watershed of Green Bay and faces serious conservation challenges. These challenges include the loss of coastal wetlands, which clean polluted water, intercept waste, protect our shorelines from erosion, provide food and shelter for migratory birds, and serve as nurseries for fish and other aquatic life.
U.S. Geological Survey (USGS) scientists are focusing on restoring natural water flow and ecological processes between coastal wetlands in the Ottawa National Wildlife Refuge (Ohio) and adjacent to Lake Erie to improve fish and wildlife habitat. Thus far, this pilot project has resulted in a model that can be used to estimate total phosphorus and total sediment loads to a reconnected wetland using high frequency turbidity and discharge measurements.
Great Lakes coastal wetlands can be separated into three specific systems based on their dominant hydrologic source and current hydrologic connectivity to the lake. These systems are different than those defined by the National Wetlands Inventory (NWI). NWI defines three systems, Lacustrine, Riverine, and Palustrine.
CoastRanger MS has been designed to explain the consequences that different management approaches have on coastal processes, natural environments and flood and coastal erosion risk. The software highlights the range of interests that need to be balanced on the coast and demonstrates the difficult decisions that have to be made in some areas. CoastRanger MS simulates typical real world scenarios and provides information on management approaches, defense types, coastal behaviour and legislation.
