TextPublication details: Downsview, ON : 1974. York University,Description: 32 p. : ill. , maps ; 28 cmOnline resources: Abstract: During the last century, nesting habitat for some ducks, such as mallards and teal, in the prairie pothole region has been drastically reduced as a result of clearing and burning of natural upland and wetland vegetation and drainage of potholes (Kiel, Hawkins, Perret,1971). Reduction of cover has not only limited nesting sites but has apparently also increased vulnerability to nest predators (Schrank,1972). These changes have come about with the expansion of agriculture and the introduction of agricultural technology which encourages and makes possible the intensive cultivation of large contiguous areas.Concern for the fate of breeding waterfowl in diminishing habitats has led to some experiments to try and find ways of planting patches of nest cover.
