Chapter 4 begins by identifying eight areas of continental significance for waterfowl, as defined in the North American Waterfowl Management Plan. The discussion leads to the heart of the chapter, which involves biological planning and conservation design for nonbreeding waterfowl in three regions—southern Oregon and northeastern California; the Great Salt Lake marshes of Utah; and the Columbia Basin of Washington and Oregon. Lastly, priority breeding waterfowl species are identified for the three primary Bird Conservation Regions within the IWJV (9, 10, and 16).
