Winter Abundance of Waterfowl and Waste Rice in Managed Arkansas Rice Fields

Flooding harvested rice fields in winter provides important ecological services, including benefits to waterfowl, other waterbirds, agronomics, and soil and water conservation. We conducted experiments in six rice fields in Arkansas during winters 2004-2006 to evaluate effects of different post-harvest stubble-management practices and flooding on abundance of dabbling ducks, geese, and waste rice. During both winters, rolled rice paddies attracted the greatest diurnal density of mallards (Anas platyrhynchos; x− = 4.18 birds/ha/survey, SE = 0.36). Burned paddies attracted the greatest...
