In addition, two 40-acre native idle plots were also fenced to evaluate waterfowl usage and success. Although drought conditions and reduced pond numbers have persisted since 1987, waterfowl usage of the plots has continued to increase. Utilization of the plots by mourning doves and sharp-tailed grouse has also continued to increase. In addition to predator fences, approximately 200 artificial nesting structures have also been implemented within the study area. These consist of horizonal metal cones, wire baskets, and plastic baskets.
Mallards account for all structure used.
Data for 1990 will be presented as well as preliminary results of nest structure usage at the Quill Lakes North American Waterfowl Management Plan project.
