| 説明 | This is one of a series of parallel forest trails about 70 feet apart created to complete a pre-commercial thinning operation. The piled limbs help minimize soil disturbance from the heavy machinery used during the operation. See photo titled “Mechanically pre-commercial thinned forestland” for more details.For the full story and other NRCS Oregon related information, go to www.or.nrcs.usda.gov/news/showcase/index.html |
