TextPublication details: 1990. Winnipeg, MB : Ducks Unlimited Canada,Description: iv, 69 p. ; 28 cmOnline resources: Abstract: The intimate spatial and temporal association of nesting waterfowl and agriculture has raised concern over pesticide use on the prairies. The prairie pothole region of North America encompasses 777,000 km, 64% of which lies in the prairie provinces of Canada. An estimated 16 million ducks utilize the prairie pothole region of western Canada; 56 to 75% of these birds nest in association with lands which are currently cropped or are likely to be cropped in the near future (Sheehan et al. 1987,Mineau et al. 1987). The magnitude, spatial association, and timing of herbicide use in relation to waterfowl ecology creates a situation with great potential for exposure of ducks to the direct and indirect effects of these chemicals (Grue et al. 1986, Sheehan et al. 1987). Substantial amounts of herbicides and insecticides are used annually on these agricultural lands. Herbicide use increased 356% in the Northern Plains region of the United States between 1964 and 1982, while insecticide use inc
