Loss of nation's wetlands is slowing, says Fish and Wildlife Service

The Fish and Wildlife Service says America's wetlands declined slightly from 2004-2009, underscoring, the service said, the need for continued conservation and restoration efforts. The service said findings reflect a continuous but diminishing loss in wetlands habitat over time.

The report says substantial losses have occurred in forested wetlands and coastal wetlands that serve as storm buffers, absorb pollution, and provide vital habitat for fish, wildlife and plants.

"Wetlands are at a tipping point," said Secretary of the Interior Ken Salazar. "While we have made great strides in conserving and restoring wetlands since the 1950s when we were losing an area equal to half the size of Rhode Island each year, we remain on a downward trend that is alarming. This report, and the threats to places like the Mississippi River Delta, should serve as a call to action to renew our focus on conservation and restoration efforts hand in hand with states, tribes and other partners."

"This report offers us a road map for stemming and reversing the decline," said Fish and Wildlife Service Director Dan Ashe. "It documents a number of successes in wetlands conservation, protection and reestablishment, and will be used to help channel our resources to protect wetlands where they are most threatened and reduce further wetland losses."

From the Fish and Wildlife Service:

The net wetland loss was estimated to be 62,300 acres between 2004 and 2009, bringing the nation's total wetlands acreage to just over 110 million acres in the continental United States, excluding Alaska and Hawaii.

The rate of gains from reestablishment of wetlands increased by 17 percent from the previous study period (1998 to 2004), but the wetland loss rate increased 140 percent during the same time period. As a consequence, national wetland losses have outpaced gains.

"In a five year period, we lost over 630,000 acres of forested wetlands, mostly in the Southeast – an area equal to half a million football fields each year," Ashe said. "We should all be concerned about the substantial loss of this diminishing resource, which helps ensure good water quality for local communities and provides vital habitat for a diversity of important wildlife species."

The southeast United States, primarily freshwater wetlands of the Atlantic and Gulf coastal plain, and the Lower Mississippi River experienced the greatest losses. Losses were also observed in the Great Lakes states, the prairie pothole region, and in rapidly developing metropolitan areas nationwide.
