Waterfowl production in planted nesting cover / Robert J. MacFarlane
Material type:
TextSeries: Thesis. (M.Sc.)Publication details: Downsview, ON : York University, 1977.Abstract: Intensified land use in what was formerly a major waterfowl production area has reduced upland nesting cover on the agricultural lands of southwestern Manitoba. Wildlife agencies in Canada and the United States are seeking ways to improve habitat in traditional waterfowl production areas now under intensive agriculture. One method being explored is to plant appropriate mixtures of vegetation on land taken out of cultivation in order to increase both the quantity and the quality of nesting cover and to increase density of nests and success of hatching.The present work is a comparative study of waterfowl production on a 100 acre (40.5 ha) cover planting surrounded by a control area of agricultural land in southwestern Manitoba. It sought to identify factors in the cover planting which might influence species composition of ducks, density of breeding pairs and nests, success and temporal sequence of nesting and brood mortality. Destroyed and hatched nests were compared on both sites wit
