U.S. land area covers nearly 2.3 billion acres. The proportion of the land base in agricultural uses has declined from 63 percent in 1949 to 51 percent in 2007. Gradual declines have occurred in cropland and pasture and range, while grazed forestland has decreased more rapidly. In 2007, 408 million acres of agricultural land were in cropland (down 17 percent from 1949), 614 million acres were in pasture and range (down 3 percent), 127 million acres were in grazed forestland (down 52 percent), and 12 million acres were in farmsteads and farm roads (down 19 percent). Nonagricultural uses increased largely due to a fourfold increase in National Parks and National Wilderness/Wildlife areas, particularly in Alaska.
