| Abstract: | Basic information obtained from the July Waterfowl Production Survey is presented in 32 Appendix tables for the period 1955-71. The discussion of the data is minimized because the report is designed primarily to make the data available to waterfowl biologists and other interested individuals. Data presented include: (1) the number of July ponds, (2) the brood index, (3) the average size forClass II and Cia s s !II broods, and (4) the late nesting index. These statistics are presented for each stratum surveyed. A few of the obvious correlations are discussed, although more refined analyses of the data will be presented in the Mallard Study reports. Furthermore, additional supporting information will be available for the mallard reports. |
