Book Description
Duck nesting in Conservation Reserve Program (CRP) fields was evaluated in 1989 and 1990 to determine the post-year effects of emergency haying.Due to severe drought some CRP fields were released in 1988 for emergency haying with the provision that 10% be left in idled strips and some fields were released in 1989 with the provision that 25% be left in idled blocks. Visual obstruction readings were used to index vegetation height-density. A cable- chain drag was used to find duck nests, and flush ring-necked pheasants (Phasianus colchicus) and white-tailed deer (Odocoileus virginianus) in 27 CRP fields in 5 eastern South Dakota counties. Duck nesting data in hayed and idled strips, hayed and idled blocks, and idled fields (not released for haying) were used to evaluate post-year haying effects on duck nest density and success. In 1989 mean residual and mean peak green growth vegetation visual obstruction readings in idled strips were significantly greater (P

The Influence of Habitat Features on Grassland Birds Nesting in the Prairie Pothole Region of North Dakota

Book Description
Results of habitat fragmentation studies on grassland and wetland birds are not consistent. Some studies have found positive relationships among abundance, nest success, field size, and distance to edges, whereas others have found no relationship. One reason for differing results may be the landscape composition in which the study took place. I examined how landscape composition influenced relations among: 1) occurrence and abundance of grassland songbirds and field size and 2) nest success of ducks, field size, and edges. I also investigated the effects of mowing on grassland songbirds, and how landscape features, such as amount of perennial grassland, and predator community composition influenced the nest success of ducks in fields. The study took place in the Prairie Pothole Region of central North Dakota during the 1996-1997 breeding seasons. Two types of 6.4 x 6.4 km study areas were selected based on the amount of perennial grassland they contained: 15-20% and 51-55%. The remaining portion of the study areas was primarily cropland and wetland.
