KISSIMMEE, Fla. -- The federal government says it will announce a major restoration project for a portion of the Florida Everglades.

The U.S. Department of Agriculture is scheduled to announce details Monday in Kissimmee. It says the project will restore and protect wetlands and improve water quality in the northern Everglades. Officials say it will provide habitat for rare and endangered species.

Efforts to restore the Everglades have been slowed by lack of funding and court battles.

The entire wetlands once covered more than 6,250 square miles, but has shrunk by half, replaced with homes and farms and a 2,000-mile grid of drainage canals. The Everglades has lost 90 percent of its wading birds, and 68 threatened or endangered species face extreme peril.
