Beaconia Marsh biological evaluation for waterfowl and management recommendations / Don Sexton.
Material type:
TextPublication details: Ducks Unlimited Canada, 1983.Description: 27 p. ; 28 cmOnline resources: Abstract: Beaconia Marsh, a 175 ha wetland at the south end of Lake Winnipeg was evaluated to determine what factors limit waterfowl production and how management could be undertaken to overcome these limitations. The marsh is affected by water level changes on Lake Winnipeg due to wind and manipulation by Manitoba Hydro. This can affect vegetation and nesting birds. Upland areas for nesting are also limited. To overcome the above,a dyke to separate the area from Lake Winnipeg and thereby dampen water level changes is recommended. Management of the enclosed cell would include drawdowns and the construction of up to 45 nesting islands. With management waterfowl production of up to 1,080 ducks per year can be anticipated. Development will also benefit other wetland wildlife,particularly muskrats.
