Effects of fall burning of vegetation in agricultural lands of Southwestern Manitoba on duck nesting habitat and production. W.F Cowan
Material type:
TextPublication details: MB : 1976Online resources: Abstract: Burning of vegetation in agricultural regions of southwestern Manitoba is practiced annually on a broad scale, as dry conditions permit.Concern has been expressed in the past over the destruction of large tracts of native plants that provide winter and summer cover, food, and protective nesting sites for ground-nesting birds, other birds, small mammals, and deer. Stoudt (1967) strongly urged that this practice be investigated as to the extent of loss of nesting cover for waterfowl and the effect on reproductive success. Fritzell (1975) reported on this aspect during a two year study in the rural municipality of Odanah. He found a significant reduction in nesting effort in burned areas for all ground nesting ducks except blue-winged teal (Anas discors), and direct destruction of nests by fire, mainly of the early nesting species:mallards (Anas platyrhynchos), and pintails (Anas acuta). Since then, no further studies of this type have occurred on agricultural lands.
