Effects of Mechanical Manipulation and Time on Lead Pellet Distribution in Arkansas Wetlands

Lead poisoning occurs when birds forage in habitats containing lead pellets and ingest and store pellets in their digestive systems. Lead pellets have been banned from use in waterfowl hunting in the United States since 1991; however, residual pellets may remain in wetlands and be available to foraging waterfowl. The purpose of this study was to evaluate changes in lead pellet distribution over time and to determine effects of soil disturbance (disking) on the prevalence of lead pellets in surface and subsurface soils of a 423-ha managed wetland in the Mississippi Alluvial Valley of...
