Migratory Waterfowl is a 1:24,000-scale, polygon feature-based layer that depicts the concentration areas of migratory waterfowl at specific locations within Connecticut. Paul Merola, former DEP Wildlife Biologist, and Greg Chasko, DEP Wildlife Biologist, identified the migratory waterfowl concentration areas based on the Northeast Coastal Areas Study, Joseph Dowhan, 1991 (see Supplemental Information) as well as by using midwinter surveys, breeding surveys and personal observations.  The concentration areas are primarily found along the shoreline and the lower tributaries and wetlands of major Connecticut rivers. In addition to depicting the concentration areas, the potential waterfowl species associated with each polygon have been identified and are listed in the attribute table as boolean values indicating their presence or absence.  The intent of this datalayer is to assist in the identification of migratory waterfowl resource areas in the event of an oil spill or other condition that might be a threat to waterfowl species.  This layer identifies conditions at a particular point in time.  It is not updated and it is not a complete representation of all areas of migratory waterfowl in Connecticut.

Migratory Waterfowl is 1:24,000-scale data. It depicts concentration areas of migratory waterfowl in Connecticut.  The intent of this datalayer is to assist in the identification of migratory waterfowl resource areas in the event of an oil spill or other condition that might be a threat to waterfowl species.  This layer is not intended for maps printed at map scales greater or more detailed than 1:24,000 scale (1 inch = 2,000 feet.)

This layer was produced in conjunction with a study prepared for the U.S. Fish and Wildlife Service.  The results of the study are detailed in the final report entitled  "Final Report  Northeast Coastal Areas Study:  Significant Coastal Habitats of Southern New England and Portions of Long Island, New York", dated August 1991, authored by Joseph Dowhan, U.S. Fish and Wildlife Service, Northeast Estuary Office, Charlestown, Rhode Island.  The report can be accessed online at http://training.fws.gov/library/pubs5/necas/begin.htm.

Includes Migratory Waterfowl Concentration Area features such as a narrative identification of birds located within each polygon area, migration status of the area, whether an area is occupied, general comments, and individual attribute fields for each waterfowl species, containing boolean values of 0 (species does not exist) or 1 (species exists).

Logical consistency for this layer is unknown.  

The completeness of the data reflects the feature content of the data sources, which include the Northeast Coastal Areas Study, Joseph Dowhan, 1991 (see Supplemental Information), midwinter surveys, breeding surveys and personal observations by DEP Wildlife Biologists Paul Merola and Greg Chasko.  The Migratory Waterfowl layer is complete in the sense that it accurately reflects the contents of the above source information available at the time the State of Connecticut, Department of Environmental Protection created the layer. However, this layer is not meant to represent all migratory waterfowl areas in Connecticut.  This layer is not updated.

The Migratory Waterfowl layer retains the feature types and information identified by the State of Connecticut, Department of Environmental Protection and obtained from the Northeast Coastal Areas Study, Joseph Dowhan, 1991, midwinter surveys, breeding surveys and personal observations by DEP Wildlife Biologists Paul Merola and Greg Chasko.  The accuracy of attributes is not known.  Values are within defined domains. 

The horizontal positional accuracy of this data is unknown.
