U.S. Fish & Wildlife ServiceFOR non-AGOL ACCOUNT HOLDERS, DOWNLOAD THIS GEOSPATIAL DATA HERE: https://gis-fws.opendata.arcgis.com/search?tags=lmvjv We defined a wetland complex as an area of appropriate size for conservation planning with suitable water coverage and persistence, heterogeneity and structure of vegetation, energy density and quality, and sanctuary to provide all of the resources needed by ducks during a portion of the non-breeding period (late fall to early spring). Based on this definition, we developed three primary sub-models for those factors that we could measure geospatially. We developed sub-models for Wetland Type to capture water coverage and heterogeneity of vegetation, Sanctuary, and Energy. The three sub-models were combined into a final Wetland Complex model. Our final Wetland Complex Model highlights several areas on the landscape where multiple habitat components (e.g., optimal configuration of wetland types) are present and create important focus areas for waterfowl conservation planning. The highlighted red areas are where we would predict to see high waterfowl use throughout the winter. The highlighted red areas could also be used as anchor points to improve the surrounding landscape to increase attractiveness to waterfowl. The vector version of this data loses some of the detail and nuance that the original data retains. Please be aware when using the vector data that it is not as precise as the raster format of this data.ArcGIS FeatureLayerhttps://hub.arcgis.com/datasets/2f3c453b0ef945698f9b290ee80dec4c_0engU.S. Fish and Wildlife Service Open DataPublicWetland Complex DSM for Waterfowl thematic [United States]Web servicesUnited StatesLast Modified: 2025-09-19
