Wildfire Threatens Historic Doerner Fir, One of the World’s Tallest Trees
A significant wildfire is challenging firefighters in the Oregon Coast Range, as flames engulf the upper reaches of the Doerner Fir, a coastal Douglas-fir estimated to be at least 450 years old. The tree, standing at 325 feet tall and boasting a diameter of 11.5 feet, is considered one of the world’s tallest of its species.
The Battle to Contain the Blaze
Fire crews were alerted to the blaze on Saturday, August 16, and quickly mobilized, utilizing drones, aircraft, and ground teams to combat the fire. Initial reports, shared by the Coos County Forest Protective Association on Sunday, August 17, indicated flames extending down the trunk from the treetop. Despite a week of intensive effort, extinguishing the fire has proven challenging, though crews have successfully prevented its spread to the surrounding forest.
As of Thursday, August 21, firefighters are collaborating with arborists to address remaining hotspots near the tree’s crown. “Firefighters will remain on scene to ensure the fire doesn’t flare up again, and fire lines are in place around the tree, though no burning debris has fallen or threatened the line,” stated the Coos FPA in a recent update.
Extent of the damage
Bureau of Land Management spokesperson Megan Harper reported on Tuesday, August 19, that approximately 50 feet of the Doerner Fir’s crown had been lost to the fire. While this impacts the tree’s claim to being among the world’s tallest, Harper expressed optimism that the tree would survive the ordeal.
Pro Tip: wildfires can spread rapidly, especially in dry conditions. Staying informed about fire risks and following safety guidelines is crucial.
Investigating the Cause and Facing a Warming Climate
Officials are currently investigating the fire’s origin, having ruled out lightning as a cause based on available weather data. The Oregon Forest Resources Institute notes that forest fires are historically infrequent in the Oregon Coast Range, occurring only once every 200 to several hundred years in a given area. The fact that this fire is impacting such a prominent landmark is described as “a very unique situation” by Harper.
“I think everyone would be super disheartened to learn that maybe it would be human-caused,” Harper stated, highlighting concerns about potential negligence.
Persistent drought conditions and above-average summer temperatures are believed to have contributed to the fire’s spread.These conditions are exacerbated by climate change, posing an increasing threat to the nation’s oldest and largest trees, wich have historically withstood centuries of environmental fluctuations.
Did You Know? Coastal Douglas-fir trees are known for their longevity and resilience, but even they are vulnerable to the impacts of climate change.
Key Data: Doerner Fir Wildfire
| Date of Initial Report | Tree Height | Tree Diameter | Area Affected | Current Status |
|---|---|---|---|---|
| August 16, 2025 | 325 feet (99 meters) | 11.5 feet (3.5 meters) | Approximately 50 feet of crown | Fire contained, hotspots remain |
The Bureau of Land management has closed the area surrounding the Doerner Fir to the public while firefighting operations continue. Additional drone flights with infrared technology are planned to identify remaining hotspots,and a helicopter remains on standby should the fire escalate.
What steps can be taken to mitigate the risk of wildfires in vulnerable forest ecosystems? How will climate change continue to impact the health and survival of ancient trees like the Doerner Fir?
The Growing Threat to Old-Growth Forests
The Doerner fir fire underscores a broader trend: the increasing vulnerability of old-growth forests to wildfires. These forests, vital for biodiversity and carbon sequestration, are facing unprecedented challenges from climate change, including prolonged droughts, higher temperatures, and more frequent extreme weather events. The impact of these changes extends beyond individual trees, affecting entire ecosystems and the communities that depend on them. Understanding the complex interplay between climate change, forest management practices, and wildfire risk is crucial for developing effective conservation strategies.
