Book Description
This report summarizes July waterfowl production survey data collected by personnel of the Bureau of Sport Fisheries and Wildlife and other cooperating agencies during the 1955-71 period. In recent years the survey has been used to monitor waterfowl populations on approximately 855,700 square miles of the North American breeding range. To enable this report to be timely, analysis and discussion are kept to a minimum, although some obvious relationships are described. Summaries of the basic information collected during the survey are presented in tabular form in the Appendices. Appendix A refers to the data obtained in the southern Prairie Provinces of Canada; Appendix B, northern Prairie Provinces and the Northwest Territories; Appendix C, North Dakota, South Dakota, and Montana; Appendix D, Minnesota; and Appendix E, northwestern Ontario.
