Sisters Ranger District plans to burn up to 11-hundred acres this year. Prescribed fire units will take place on three sites, adjacent to Highway 20, within the Sisters Area Fuels Reduction (SAFR) area, and in the Metolius Basin. eather permitting, Sisters Ranger District firefighters hope to begin spring prescribed fire operations next week. Residual moisture at this time of the year allows for low-intensity fire while removing ladder fuels and hazardous fuels loading. The planned units are a continuation of treatments to help the natural ecosystem and reduce hazardous fuels that can ignite high intensity fire events during the normal fire season. Traffic control measures will be enforced on major roadways during burn operations. Residents in the town of Sisters, as well as outlying areas in the Metolius Basin are advised to keep their windows and doors closed during the night hours to avoid potential smoke impacts.
