Cover Photo by Don Paul ACKNOWLEDGMENTS This plan was developed with input from dozens of individuals in the U.S. and Canada; we thank everyone for their help. Plan participants are listed in Appendix A. The Intermountain West Shorebird Conservation Plan (Oring et al. 2001) provided some of the background material from which the Intermountain West Waterbird Conservation Plan was developed. Funding for development of this plan was provided by the U.S. Fish and Wildlife Service Migratory Birds and Habitat Programs (USFWS), Bureau of Land Management, and the Bureau of Reclamation. Dan Casey of the American Bird Conservancy provided Figure 1. The Waterbird Conservation Council endorsed this plan in March 2005. Gary Cox of Cox and Company, Black Earth, Wisconsin provided the cover design. Nanette Seto, Tara Zimmerman, and Suzanne Fellows of USFWS provided reviews and edits on the document. Michelle Whalen (USFWS) and Laurie Litman (InfoWright) edited and formatted the document for publication.
