1 Forestry & Society Forests of the U.S. HORT/RGSC 302 J.G. Mexal

2 Importance of forests National forests serve as watersheds providing water for 60 million people Roadkills total 1 million/day 2000 invasive species in US infesting 3.5 million ac and costing $120 billion Recreation: –36 million off-roaders –71 million birders spending $32 billion

3 Forestry Facts Pre-consumer recycled paper– trimmings and scraps before sales Post-consumer recycled paper – recovered after use (newspapers, cardboard, etc) Mechanical Pulping: up to 95% efficiency – used in newsprint Chemical Pulping: dissolves lignin,bleached, stronger, lower yield

12 Forestry & Society A brief history of time USDA formed in 1862 to improve food production CSRS formed in 1887 by Hatch Act USFS formed in 1905 (moved from Dept of Interior to Dept of Agriculture) CES formed in 1914 by Smith-Lever Act SCS (NRCS) formed in 1935 ARS formed in 1953

13 Forestry & Society Forests of the U.S.--Public Lands US Forest Service (1905) –192 million acres in 43 states (25% of public lands) –156 national forests in 43 states –85% in 13 western states Bureau of Land Management (1812) –341 million acres (~1/8 of US total land base) –Administers mineral leases on 732 million acres of federal land National Park Service (1872) –79.5 million acres (49 states, except Delaware)(11%) Bureau of Indian Affairs –55 million acres (7%)

18 Forestry & Society Forests of the U.S.--Laws L (1924) & U (1939) Regulations –Allowed primitive areas (L) and wilderness, wild, & recreational areas to be designated. Multiple-Use Sustained-Yield Act (1960) Forest & Rangeland Renewable Resources Planning Act (RPA) (1974) National Forest Management Act (NFMA) (1976) –incorporate other uses of forest in planning
