A major portion of the prime waterfowl breeding habitat in western Canada occurs in areas of intense agricultural activity. Modifications to small wetlands in these areas (burning, mowing, clearing, filling, and draining) are commonly carried out by agriculturalists in an effort to increase farm yields (Fritzell 1975). Such disturbances area thought to reduce waterfowl use and productivity, although few studies have documented this. This study was designed to monitor breeding duck populations on burned and unburned wetlands to determine if occupancy rate is independent of agricultural burning of pond margins.
