Fire personnel on the Barlow Ranger District plan to burn up to 427 acres in the Mt. Hood National Forest this fall.  Burning operations could begin as early as Friday and continue through the next few weeks if weather and moisture levels remain favorable.  The planned burns are in the South Rock and Rocky 79 prescribed fire units, located about three miles southwest of Pine Hollow and five miles west of Wamic, within the footprint of the Central Wasco County All Lands Joint Chief Project.  Prescribed burning in this area will improve landscape resilience to disease and fire as well as increase overall forest health and wildlife habitat.  Firefighters successfully burned 180 acres in the South Rock unit last spring and hope to complete the remaining 220 acres this fall.  Rocky 79 will be the first prescribed fire unit to receive treatment as part of the Rocky Restoration Project.  Access to roads within the burn perimeter may be temporarily restricted while the burn is active.  Smoke may be visible in the vicinity during the burn and for a few days afterward.
