The Relationship Between Moist-Soil Plant Seed Production And Drawdown Date In An East-Central Illinois Subimpoundment Managed For Waterfowl Hunting, Jeffrey M. Ver Steeg
Masters Theses
Faced with increasing costs and decreasing federal funds, wildlife managers are turning towards more energy effecient and economical methods of attracting fall migrating waterfowl. The production of food by natural moist-soil plants can be encouraged in low lying areas by timely dewatering and reflooding. This study was designed to determine which of two drawdown dates would result in the greatest seed production by plants known to be valuable waterfowl foods.
A late July 1984 drawdown in an east-central Illinois subimpoundment produced significantly more smartweed (Polygonum spp.) and pigweed (Amaranthus tamariscinus) seed than did a late March 1985 drawdown. …
