MONTANA — The U.S. Forest Service plans to create a logging unit across regional national forests, seeking to boost economic stability by committing to process timber only via local businesses. The new Sustained Yield Unit – a concept created by 1944 federal law – would include 22 Montana counties and all of Helena-Lewis & Clark and Beaverhead-Deerlodge national forests, as well as most of Custer Gallatin. …Speaking for the Governor’s Office, Amanda Kaster, director of Montana’s Department of Natural Resources and Conservation, expressed the state’s strong support. …The draft plan estimates that the unit would directly support 192 jobs per year over the next decade, plus an additional 225 jobs via economic ripple effects. But the Marks saw the yield unit’s harvest plan as inadequately ambitious. …Barb Cestero, Montana director at the Wilderness Society, feared that given the Forest Service’s recent staff cuts, a potential over-emphasis on logging could be problematic.
