The U.S. Forest Service turns a bit more green.Dombeck is the first director to admit what critics have contended for years - that the taxpayers are taking huge losses on the Forest Service contracts with the timber industry. Using the agency's own data, the Wilderness Society estmates that the Forest Service could save $500 million over the next five years simply by eliminating "below-cost" timber sales. These costs include the roads that the Forest Service builds to enable logging companies to haul the timber out, and the surveying and legal expenes of the timber contract.As a result, the Wilderness Society says, a 65-foot, 100-year-old pine tree that will produce thousands of dollars worth of lumber products can cost the lumber company as little as $2.
