Forest Service says it failed to account for climate change in New Mexico blaze

When the U.S. Forest Service started an intentional fire in the Santa Fe National Forest in early April, the aim was to reduce the risk of a destructive blaze. But the agency relied on poor weather data and failed to understand how climate change had dried out the landscape, ultimately setting a fire that would explode into the largest wildfire in New Mexico’s history, the Forest Service said in a new report published on Tuesday.
“Climate change is leading to conditions on the ground we have never encountered,” Forest Service chief Randy Moore said in an introduction to the 80-page report. “Fires are outpacing our models and … we need to better understand how megadrought and climate change are affecting our actions on the ground.”
Calf Canyon/Hermit’s Creek, which began as two fires and combined to burn more than 341,000 acres and torch hundreds of homes as of Tuesday afternoon, has become the latest flash point in the debate over whether authorities should use prescribed burns, intentional fires meant to thin out flammable vegetation to lower the risk of more damaging blazes.
The review found the planning and analysis for the April 6 prescribed burn was done according to the Forest Service’s current standards and policies, and was carried out in an approved way. But the fire was being set “under much drier conditions than were recognized.”
“Persistent drought, limited overwinter precipitation, less than average snowpack” and fuel accumulation “all contributed to increasing the risk of fire escape,” the report said.
The report also found that numerous details about weather conditions were “overlooked or misrepresented,” and noted some automated weather stations nearby weren’t functioning. Those setting the fire also “did not cease ignitions or suppress the prescribed fire after clear indications of high fire intensity and receptive fuels.”
On May 20, Moore halted all prescribed burns on National Forest lands for 90 days as a safety precaution due to ongoing harsh weather. But he and others insist that such intentional burning is necessary to avoid disastrous wildfires, and that the vast majority of them do not cause problems.
“Wildfires are threatening more communities than they ever have. Prescribed fire must remain a tool in our toolbox to combat them,” Moore said. “Unfortunately, the effects of climate change are narrowing the windows where this tool can be used safely.”
Timothy Ingalsbee, executive director with Firefighters United for Safety, Ethics, and Ecology, said authorities “can no longer manage fire according to the calendar date” and should incorporate climate data more thoroughly into their models. He also said firefighters need to intensify prescribed burns when weather conditions are favorable. He warned that halting prescribed burns for three months could have consequences later this summer.
“Areas that should have burned under controlled conditions will burn under extreme conditions,” he said.
In New Mexico, many have been outraged that authorities set the fire that ultimately displaced thousands of people from their homes.
Rep. Teresa Leger Fernandez, D-N.M., said the report pointed out numerous errors by the Forest Service.
“Forest Service failures destroyed many rich and proud New Mexico communities,” she said in a statement, according to The Associated Press. “The rains may cause a second flood disaster. As the report notes, the Forest Service put numerous homes, communities, lives, historic sites, and watersheds at risk.”
