Disappearing ducks?
Date:2/1/2010

The loss of wetlands in the prairie pothole region of central North America due to a warmer and drier climate will negatively affect millions of waterfowl that depend on the region for food, shelter and raising young, according to research published today in the journal BioScience.

The new research shows that the region appears to be much more sensitive to climate warming and drying than previously thought.

"The impact to the millions of wetlands that attract countless ducks to these breeding grounds in spring makes it difficult to imagine how to maintain today's level of waterfowl populations in altered climate conditions," said Dr. Glenn Guntenspergen, a U.S. Geological Survey researcher and one of the report authors. "Parents may not have time to raise their young to where they can fly because of wetlands drying up too quickly in the warming climate of the future," he added.

A new wetland model developed by the authors to understand the impacts of climate change on wetlands in the prairie pothole region projected major reductions in water volume, shortening of the time water remains in wetlands and changes to wetland vegetation dynamics in this 800,000-square kilometer region in the United States (North and South Dakota, Montana, Minnesota and Iowa) and Canada.

Many wetland species -- such as waterfowl and amphibians -- require a minimum time in water to complete their life cycles. For example, most dabbling ducks -- such as mallards and teal-- require at least 80 to 110 days of surface water for their young to grow to where they can fly and for breeding adults to complete molting, the time when birds are flightless while growing new feathers. In addition, an abundance of wetlands are needed because breeding waterfowl typically isolate themselves from others of the same species.

"Unfortunately, the model simulations show that under forecasted climate-change scenarios for this region (an increase of 4-degrees Cel
