The USGS developed select Web-based decision tools to help users understand the information available to address complex Chesapeake Issues. The tools are used by stakeholders to inform restoration and conservation decisions in the Chesapeake Watershed. Many of the tools are developed in cooperation with the Chesapeake Bay Program and are hosted on their website.

####                 Geonarrative: Nontidal Network Mapper              

The Nontidal Network Mapper geonarrative is a data-driven, interactive narrative that shares the short-term water-year nutrient and suspended-sediment load and trend results for the Chesapeake Bay Program’s non-tidal network (NTN). The mapper provides the primary findings for nitrogen, phosphorus and suspended-sediment trends, and gives the user tools to further examine results.

####                 Habitat Vulnerability Assessment for Wintering American Black Ducks              

We estimated food availability among five main wetland cover types used by overwintering American Black Ducks: subtidal, fresh water, high marsh, low marsh, and mudflat. Bioenergetics models used to inform North American Waterfowl Management Plan (NAWMP) can be simplified into two major components: energetic demand and energetic supply.
