The purpose of this extension bulletin is to guide the management of nesting ducks on peninsulas on public and private lands. Managing peninsulas for ducks is a relatively new strategy that was developed in the grassland region of western North America. Information contained in this bulletin is primarily from studies conducted by biologists working at the Northern Prairie Wildlife...

During the past few decades numbers of some species of upland-nesting birds in North America have declined. Duck species such as mallard (Anas platyrhynchos), northern pintail (A. acuta) and blue-winged teal (A. discors) have declined since the early 1970s and have remained low since 1985 (Caithamer et al. 1993). Some grassland-dependent nonwaterfowl species also have declined since 1966...

1. A major cause of degradation and loss of stream fish is alteration of physical habitat within and adjacent to the channel. We describe a potentially efficient approach to fish restoration based upon the relationship between fluvial hydraulics, geomorphology, and those habitats important to fish.2. The aquatic habitat in a low-gradient, alluvial stream in the Ozark Plateaus...

Waterfowl that nest in uplands in the prairie pothole region have had low recruitment rates in recent decades, primarily because of predation. The loss of breeding waterfowl and their progeny has generated interest in management techniques that safeguard incubating hens and their eggs. Developing islands and peninsulas for nesting waterfowl has potential because these sites are naturally

Redheads are one of five common diving duck species in North America. They are in the same taxonomic group as the pochards or bay ducks and are most similar in appearance and behavior to the canvasback. Smaller body size, late breeding, wintering in southern areas, and tolerance to salt in winter and in breeding areas differentiate the redhead from the canvasback and suggest an...

Habitat fragmentation from intensified farming has concentrated nesting waterfowl and their predators in the remaining, relatively small untitled habitats of the prairie pothole region in the United States. The areas of land that have been enrolled in the Conservation Reserve Program (CRP) in this area could help disperse these concentrations and reduce losses to predators. The presence...
