Long-term Declines in Nest Success of Prairie Ducks
Appendix A
Published and unpublished sources of nest success data for 5 species of upland-nesting ducks in the Prairie Pothole Region. 1935-92. Unpooled refers to nest success estimates that were kept separate for each species at each site in each year. Pooled refers to nest success estimates pooled for all species present at each site each year. Note that the pooled dataset may include more species and more nests. The number of estimates of nest success (n) and the number of nests on which each study was based are given. Data from islands or predator control sites were not included. NWA = national wildlife area, WMD = wetland management district, WPA = waterfowl production area.
