CFPA release - Firefighters worked Tuesday to monitor hot spots and improve containment lines on the Doerner Fir Tree Fire, east of Coquille, Ore.  An infrared drone flight this morning showed one area of heat approximately 280 feet up the tree, where fire is burning a cavity into the tree. Firefighters monitored this hot spot while exploring options to extinguish the fire in this area of the tree. The flight also showed that yesterday’s helicopter bucket drops successfully cooled the very top of the tree.  As the weather trends hotter and drier this week, crews continue to reinforce containment lines around the base of the tree to reduce the risk of any fire spreading. A helicopter and additional resources are on standby, available to respond if fire activity increases.  The Coos Bay District issued an emergency closure of public lands for the area surrounding active fire suppression activities. The closure includes all BLM-administered lands in T27S R9W Sections 29 and 31, the Doerner Fir Trail, and BLM Road 27-9-21.0.  BLM investigators have ruled out lightning as a cause of the fire based on weather data, and the investigation into the cause of the fire continues.  The Doerner Fir Tree Fire was first reported on Saturday, Aug. 16, 2025. Standing 325 feet tall with a diameter of 11.5 feet, the Doerner Fir is one of the largest coastal Douglas-fir trees in the world.
