Waterfowl utilization of borrow pits and wet meadows at Salt Point,Manitoba. Robert O. Bailey
Material type:
TextPublication details: 1976Online resources: Abstract: Eighty-five percent of the breeding ducks on a Salt Point roadside transect used borrow pits rather than other wetlands. Utilization was highest in May and ended in June. Blue-winged teal, green- winged teal and mallard were the most numerous species. Factors correlated with high use were size, distance from road, depth; negative correlates were percent wooded vegetation surrounding the pond, distance to permanent water. Proximity to wet meadows and other borrow pits, percent emergents, and presence of loafing sites did not influence use. Many shorebirds and other aquatic birds also used borrow pits. Hens moved their broods overland to rearing habitat shortly after hatching, the influence of this activity on productivity was unknown. Recommendations for construction of borrow pits are present.
