Conservation: Ducks in a Crowded World

Sustaining healthy waterfowl numbers will be a great challenge as the earth's human population grows

There is nothing more important to sustaining duck populations than keeping prairie wetland basins intact so they can recharge whenever it gets wet. The spectacular duck populations of 2011 offer ample proof of this assertion.

In today's interconnected world, local events can have global impacts that affect all of us wherever we live. The same is also true of the habitats that support waterfowl. The competition on the landscape between habitat and food production is already heating up. And traditional conservation "fixes" like buying and managing land exclusively for wildlife will not be enough. It's a matter of scale, affordability, and social values. Conserving habitat may lose public support in the future if this work is seen as being in direct competition with the economy and human well-being.

How can we find socially acceptable ways to sustain waterfowl and their habitats in the world's confined breadbasket? First, we must find more common ground. Raising awareness of the many ecological services that wetlands and adjacent grasslands provide for society should build support for public policies that conserve these important waterfowl habitats. Interconnected wetlands help remove excess nutrients from watersheds, moderate the extent and timing of runoff that contributes to downstream flooding, help recharge local aquifers, and in some situations contribute to the capture and storage of atmospheric carbon dioxide. All of these wetland functions are important to people and communities as well as wildlife and the environment. Moreover, soil erosion can be reduced and fertility slowly enhanced by better management of tillage and crop residue. On intensively farmed prairie landscapes, cultivating winter cereals that efficiently use limited soil moisture will also provide nesting cover for breeding pintails and other dabbling ducks. In some areas of the pothole country, grass-based agriculture, such as cattle grazing and forage production, may be more sustainable in terms of energy input and water use than is crop production. Waterfowl conservationists and ranchers have long had overlapping interests that we should continue to steward.

If public-sector investments in conservation are diminished by periodic spending cuts, we must also work to ensure that sufficient policy "backstops" are in place to conserve critical habitat when development pressures increase. Strengthening wetland protections formerly provided by the Clean Water Act in the United States, sustaining conservation provisions in U.S. and Canadian agricultural policies, and nurturing stronger provincial wetland policies in Canada are high priorities. There is nothing more important for sustaining duck populations than keeping prairie wetland basins intact so they can recharge whenever it gets wet. The spectacular duck populations of 2011 offer ample proof of this assertion.  

A world with more than 7 billion people might still sustain healthy numbers of waterfowl in North America, but it won't be easy. Let us rededicate ourselves to the work required to achieve truly sustainable conditions for this continent's waterfowl as we celebrate their recent abundance and mark with some trepidation the recent arrival of our 7-billionth relative.

Declining Species Remain Cause for Concern In contrast to all the good news in 2011, three species of ducks—lesser and greater scaup and American wigeon—remained well below their long-term population averages in the traditional survey area. Note too that after a couple of decades of gradual decline, the long-term averages for these species have been dropping as well. Scaup and wigeon have shown particularly sharp declines in Canada's western boreal forest and Prairie Pothole Region. Declines among wigeon have been partially offset by significant population increases in Alaska.  
To help address the conservation needs of waterfowl in the western boreal forest, DU, the Pew Charitable Trusts, and other partners are ramping up efforts to identify and protect the region's best waterfowl breeding habitats, work with resource extraction industries to develop best practices to minimize impacts on waterfowl habitat across this vast region, and conduct research to better understand the impacts of changing land use on waterfowl and boreal wetlands.
