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. Another challenge is the bridges, dams and culverts that can disrupt the connection between those wetlands, tributary streams and the open waters of the bay. This map is intended to help resource managers identify and prioritize habitat protection and restoration in the watershed. It provides a first filter for the advance identification and comparison of opportunities to address these challenges. This GIS data can help to guide conservation investments towards sites that are most likely to result in conservation gain. However, because available datasets may be coarse in resolution and GIS-based rather than documented on the ground, the data presented here must be verified through on-site visits before proceeding. Numerous GIS layers are included so that users can turn on the layers most relevant to their organization's mission.
