PRINEVILLE, OR -- Fire managers on the Ochoco National Forest plan to take advantage of recent warm, dry weather to implement two prescribed burn projects north of Big Summit Prairie. The burns will start tomorrow and continue through the week. Firefighters plan to ignite 144 acres of juniper jackpots and a 157-acre understory burn, just north of Big Summit Prairie, about 40 miles northeast of Prineville. The goals for the prescribed burns are to improve wildlife habitat and to remove hazardous fuels.
