Population Control by Wildlife Agencies
These strategies represent a more direct means of controlling the population.
They are likely to be more expensive, controversial or difficult to implement.
The work group recommended that initial priorities should be directed at
increasing harvest by hunting before more direct means of population control
are used.
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.
