Lumber and woodworking were important to the early settlers, but the industry has since declined in commercial importance. In 2002, Iowa had 2.05 million acres (830,000 hectares) of forestland, which represents 5.7% of the state's land area. This was a 31% increase in forest area when compared to the 1974 survey's 1.6 million acres. The state's lumber industry produced 77 million board feet of lumber in 2002.
