Washington ? Mountain views in some of the country’s signature national parks are clouded by air pollution, while historical monuments are crumbling for lack of cash, a park advocacy group says.

The National Parks Conservation Assn. on Monday released its annual list of “America’s Ten Most Endangered National Parks.”

Federal Hall, where George Washington was sworn in as president, is shown in New York City's Financial District in this September 1987 file photo. The National Park Service is requesting .4 million in federal funds to restore the building, which was structurally damaged when the nearby World Trade Center collapsed during the Sept. 11 terrorist attacks.

Mojave National Preserve in California is among the newcomers to this year’s list. Among the problems cited: water drained by nearby development, illegal wildlife poaching and habitat damage from off-road vehicles.

The list also includes Yellowstone National Park, the country’s first park, and Federal Hall National Monument in New York, the lower Manhattan site where George Washington was sworn in as president. It was damaged by the collapse of the nearby World Trade Center.

“Although our national parks are protected on paper, the dangers they face continue to multiply,” said Thomas Kiernan, president of the conservation association. “Our national parks need to be protected and fully funded, and the parks must be freed from the burdens of encroaching development and air and water pollution.”

Kiernan said President Bush’s proposal to increase funding for national parks is a good start, but more is needed.

Bush has proposed $663 million for new construction, maintenance and rehabilitation projects, ranging from erecting new buildings to repairing sewer lines that threaten waterways. That proposal for the year beginning Oct. 1 is about $2 million more than Congress appropriated for the current year.

The parks association is lobbying Congress for more money to hire additional park employees, such as archaeologists and biologists, and catch up on a substantial maintenance backlog.

The commission’s list incorporates threats that range from major, endemic problems such as air pollution in the Great Smoky Mountains along the Tennessee-North Carolina border to a luxury home developer wishing to build inside Valley Forge Historical Park in Pennsylvania.
