"Duck stamp" dollars reserve native prairie tracts "Duck stamp" dollars reserve native prairie tracts
Ducks and wetlands are inseparable in the prairies. Hunters know this, bird watchers know this, wildlife managers know this, and most importantly people who manage the croplands and rangelands know this. The 1,746 tracts of native prairie within these upland-wetland complexes known as Waterfowl Production Areas are not the only lands purchased with "duck stamp" dollars. Considerable...

Characteristics of central North Dakota wetlands determined from sample aerial photographs and ground study Characteristics of central North Dakota wetlands determined from sample aerial photographs and ground study
Wetland characteristics were assessed from a systematic sample of 66 plots, 3.22 km2 each, drawn from a 10,041-km2 study area in central North Dakota. Each plot was visited once and 8 sets of aerial photographs were obtained in 3 years. Density of wetland basins was 11.00 ha/km2, and area averaged 9.7 ha/km2. Seasonal and temporary wetlands were most abundant; semipermanent wetlands...

Grazing intensity effects on the breeding avifauna of North Dakota native grasslands Grazing intensity effects on the breeding avifauna of North Dakota native grasslands
A breeding bird census and plant survey was conducted on 180 samples of lightly, moderately, and heavily grazed and hayed native grasslands in North Dakota in 1974. The ten most important cover plants on each of eight major physiographic landforms in three of the four regions (the Agassiz Lake Plain excluded) overlapped so extensively that only 19 species were involved: 13 grasses or...

The role of observer bias in the North American Breeding Bird Survey The role of observer bias in the North American Breeding Bird Survey
Ornithologists sampling breeding bird populations are subject to a number of biases in bird recognition and identification. Using Breeding Bird Survey data, these biases are examined qualitatively and quantitatively, and their effects on counts are evaluated. Differences in hearing ability and degree of expertise are the major observer biases considered. Other, more subtle influences are...
