HELENA, Mont. -- An Interior Department report released last week identifies 101 high-priority conservation projects across the nation as part of President Obama's initiative to protect public lands, but it said most will have to find money somewhere besides the U.S. government.

The report outlines two projects in each state and one in the District of Columbia in various stages of development, ranging from the creation of an all-season trail system in Alaska's Denali State Park to the completion of a 32-mile trail through urban areas in central Florida.

Representatives from all 50 states were asked to identify specific projects in which the federal government could form partnerships as part of the America's Great Outdoors Initiative.

Some could be completed within in a few years, while others would take several decades, said Interior Secretary Ken Salazar.

Salazar said he didn't know the total cost, and the report said the federal agency won't be able to fund most of them, "given the fiscal constraints facing the federal government."

"We could do more if we had more funding," Salazar said. "I'm hopeful that as Congress considers appropriations for the future, they will recognize conservation is important for very important reasons, such as jobs."

Many of the projects already have launched, and the Interior Department will be able to help the state and local groups leading them by reallocating existing revenue within the agency and by providing technical assistance, he said.

The agency could also help the groups by acquiring conservation easements and grants, according to the report.

The report is part of the Obama administration's conservation initiative meant to protect public land, encourage more people to enjoy the outdoors and bolster employment in tourism and recreation.
