Dana Joel Gattuso of the National Center for Public Policy Research warns that a provision in the pending farm bill will encourage increasing federal control of private lands (de facto federal ownership) via the mechanism of conservation easements.

That got me wondering just how much of the United States is owned by the federal government. Surprisingly, the information seems hard e by. A study (pdf) conducted by congressional Republicans in 2005 and based on 2004 data found that the federal government owned more than 653 million acres, about 29 percent of the nation’s total land area. But when I went to the Web site of the agency to which that document directed me, the General Services Administration, I wasn’t able to locate the 2004 report, nor any more recent report that provides updated figures.

In this 2004 article, Robert Smith claimed that no one knows how much land the government owns because there is no bureau charged with keeping track.

Granted that the amount is constantly changing as the government acquires and divests (you can peruse available properties here), I’ll go along with Gattuso’s view that we want to avoid further expansion of government land ownership. Consider, too, that the figures cited above include only the national government’s holdings: state, county, and municipal governments no doubt own millions of additional acres.
