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. 

Loads and trends in the Chesapeake Bay nontidal monitoring network: results through Water Year 2018

Data used in the mapper, and the methods used to compute trends and loads, can be also accessed from the tool.
