Approximately 21,637,000 acres (8,756,494 hectares) of forested lands were located in Colorado as of 2002. In spite of this wood resource, however, commercial forestry is not a major element of the state's economy. Lumber production in 2002 was 135 million board feet. In Colorado, forestry emphasis occurs in diverse areas: traditional forest management and stewardship; urban and community forestry; resource protection (from wildfire, insects, and disease); and tree planting and care. As of 2003 Colorado had 13 national forests; gross national forest acreage as of 2001 was 16,015,000 acres (6,481,271 hectares).
