Book Description
2008 Outstanding Academic Title, Choice Magazine From dirt bikes and jet skis to weed wackers and snowblowers, machines powered by small gas engines have become a permanent—and loud—fixture in American culture. But fifty years of high-speed fun and pristine lawns have not come without cost. In the first comprehensive history of the small-bore engine and the technology it powers, Paul R. Josephson explores the political, environmental, and public health issues surrounding one of America's most dangerous pastimes. Each chapter tells the story of an ecosystem within the United States and the devices that wreak havoc on it—personal watercraft (PWCs) on inland lakes and rivers; all-terrain vehicles (ATVs) in deserts and forests; lawn mowers and leaf blowers in suburbia. In addition to environmental impacts, Josephson discusses the development and promotion of these technologies, the legal and regulatory efforts made to improve their safety and environmental soundness, and the role of owners' clubs in encouraging responsible operation. Synthesizing information from medical journals, recent environmental research, nongovernmental organizations, and manufacturers, Josephson's compelling history leads to one irrefutable conclusion: these machines cannot be operated without loss of life and loss of habitat.

Book Description
This report summarizes annual forest inventories conducted in Ohio from 2001 to 2006 by the Northern Research Station's Forest Inventory and Analysis unit. Ohio's forest land covers 7.9 million acres or 30 percent of the State's land area, changing little in forest land area since 1991. Of this land, 5.8 million acres (73 percent) are held by family forest owners. The current growing-stock inventory is 12.3 billion cubic feet--2 percent more than in 1991--and averages 1,603 cubic feet per acre. Yellow-poplar continues to lead in volume followed by red and sugar maples. Since 1991, the saw log portion of growing-stock volume has increased by 35 percent to 41 billion board feet. In the latest inventory, net growth exceeded removals for all major species except elm.
