About 61% of New York's surface area is forestland. The most densely forested counties are Hamilton, Essex, and Warren in the Adirondacks, and Delaware, Greene, and Ulster in the Catskills. The total forested area was about 18,432,000 acres (7,459,000 hectares) in 2002, of which 15,389,000 acres (6,228,000 hectares) were classified as commercial forest, meaning they were available for the harvest of wood products such as sawlogs, veneer, and pulpwood or firewood. In 2002, lumber production totaled 464 million board feet.
Finger Lakes National Forest, the only national forest within the state, covered 16,175 acres (6,546 hectares) in 2001. The state Department of Environmental Conservation manages about 3,000,000 acres (1,200,000 hectares) in the Catskills and Adirondacks as Forest Preserves, and an additional 800,000 acres in State Forests and Wildlife Management Areas (where timber harvesting is allowed as part of their management plans).
