Northern Prairie Wildlife Research Center
Commercial harvest - Develop and permit commercial harvest. A major limitation would be developing sustainable commercial opportunities that did not conflict with hunting opportunities.
Trapping and culling of birds - Trap and kill large numbers of birds on wintering and migration areas. This would require programs to use the birds for food and/or other products.
Refuge management - Change refuge management to reduce food subsidies, roosting areas and areas safe from hunting. A major drawback to this strategy is affects on other wildlife species that also depend on these habitats.
