An embarrassment of riches: too many geese

Article Abstract:

The population of giant Canada geese, greater snow geese and lesser snow geese have risen within the past 30 years to the point that it is now becoming a problem. One control which is effective and at little or no cost to the government is the reduction of mature fowl population. Sections of the Treaty on wildfowl management should be re-written to allow regulated hunting even off-season. Commercial sale of waterfowl should be legalized as well as alternative and banned traditional hunting techniques. The practice of planting food in wildlife refugees should be discontinued.

Long-term declines in nest success of prairie ducks

Article Abstract:

A lowered nest success among the praire ducks is seen in the Prairie Pothole Region of Canada and US based on studies made in different areas and periods. Review of both published and unpublished studies conducted in Alberta, Saskatchewan, Manitoba, N. Dakota and S. Dakota from the 1937 to 1990 suggests that the decline was gradual and much lower than feared. Nest success accounts for only 10% of the variation in population of all duck species studied. The rest has been unexplained.

Effects of grazing and burning on densities and habitats of breeding ducks in North Dakota

Article Abstract:

Grazing and burning which resulted in change in vegetation in federal refuge land proved detrimental to upland waterfowl, but may be beneficial to other species. This was shown in Lostwood National Wildlife Refuge in northwestern Dakota which was subjected to the management manipulations mentioned. Waterfowl nest density and success rates are higher in refuges where brush and grass also have high density and are not subjected to vegetation management.
