Paul Hessburg had studied wildfires for three decades when he saw the very scenario he dreads most unfold in his hometown of Wenatchee, Washington.
He shares the story now in hopes of stopping the seemingly endless cycle of such stories.
“In June 2015, a wildfire threatened to destroy my hometown and almost pulled it off,” Hessburg said.
The Sleepy Hollow fire was reported at 1 p.m. on June 28, 2015. Initially, 12 homes were threatened; the fight to save them was heroic, said Mike Burnett of Chelan County Fire District 1.
“There was an active fire battle” in the Sleepy Hollow neighborhood, he said. “Mother Nature gave us a battle, but we were able to hold our own.”
The conditions were not the same in the Broadview neighborhood. The speed with which the fire dropped down off the hill was unexpected, Burnett said. Heavy fuels carried the flames, and the wind hurled embers the size of half-dollars a mile ahead.
“No one had that in their slide carousel of previous fire behavior,” he said.
At one point, Burnett could see eight homes burning just from where he was positioned. Each burning home had a “tremendous fuel load.” One spread to two spread to two dozen.
And the wind was still throwing embers into new areas, including Wenatchee’s Warehouse District. Overnight, firefighters found themselves fighting massive fires in three warehouses.
“Extraordinary actions were taken,” Burnett said. “We had them working for hours in 100-plus-degree temperatures. There was a couple of people who had IVs started, rehydrated that way and were put back out on the line.”
Everyone expected new neighborhoods to be aflame by daybreak – until it started raining.
“I’ve said to several people, ‘But by the grace of God, we didn’t have another fire start up in South Wenatchee or over in East Wenatchee.’ It was coming into No. 1 Canyon. We were going to have an active firefight that next morning as soon as the sun came up. Instead we had rain.”
One town’s heartbreak would be enough, Hessburg said. But these uncontrollable fires are not just happening in Wenatchee or Washington state. All across the West, wildfires are increasing in number, size and intensity.
And so Hessburg is taking his message – his mission – to forest communities in western Montana, Idaho, Washington, Oregon and British Columbia this spring. He spends 70 minutes with each audience, sharing the multimedia “Era of Megafires” presentation.
“There is no future without wildfire, and no future without the smoke that comes with wildfire,” the U.S. Forest Service researcher told rapt audiences this week in Missoula, Kalispell, Lincoln and Seeley Lake, Montana.
The question is not whether there will be wildfires, Hessburg counseled. “It’s how do you want your smoke? How do you want your wildfires?”
Be empowered by that knowledge of fire’s inevitability, he said, because empowerment leads to action.
“It is critical that we as homeowners and community leaders recognize that it is our responsibility to influence the way we manage our fires and our forests,” he said.
Hessburg, who works out of the Pacific Northwest Research Station in Wenatchee, described the changes wrought on Western forests by aggressive fire suppression, intensive logging, homebuilding in the wildland-urban interface, and – now – climate change.
Then he laid out the solution: a fully loaded toolbox of actions communities can take to prepare themselves and their forests to live with fire.
The statistics set off all sorts of alarms.
Across the West, “megafires” – those that burn 100,000 acres or more – are increasing in number. The rate of growth, in fact, is exponential: in acres burned over the last 30 years, and in structures burned (with as many as 3,000 homes and outbuildings lost per wildfire).
Where the Forest Service once spent 17 percent of its budget on fire suppression, it now spends 57 percent – and the percentage just keeps getting higher.
And those aren’t the only costs, Hessburg said, drawing on the example of 2015, when $2.1 billion was spent on wildfire suppression.
That’s an impressive number, he said, but it’s only part of the story. When you add in the cost of rebuilding structures, lost business revenues, and replacing and rebuilding infrastructure, the cost increases by 24 times.
So the true cost of wildfires in 2015? $50 billion.
And that’s not even what Hessburg wants his audiences – he’ll be on the road until mid-July with the megafires presentation – to remember. He wants them to think back and see the faces and stories of ordinary people whose lives were upended by a wildfire they never expected.
In Wenatchee, one of those homeowners was Scott Marboe, who watched the Sleepy Hollow fire crest the hill behind his house at 8 p.m. and lob a fireball onto his neighbor’s house, which exploded in flames.
“And that was all,” Marboe said. “It was total devastation. It was the weirdest, most shocking feeling I’ve ever had. It was horrible, just horrible.”
Marboe and his family could not bring themselves to rebuild in their burned-out neighborhood.
He could only hope that one good thing came from the ruins of his life.
“Take our experience and use it,” he said, “so other people don’t have to go through this heartbreak.”
Fire had a starring role in the landscape for millennia before humans started disrupting things. Every living being’s life history was shaped by fire.
Hessburg tells a few of the stories in his presentation: how ponderosa pines grew thick skins to survive the frequent, valley bottom ground fires that thinned the understory and left the big trees; how pileated woodpeckers grew to rely upon charred snags for bug meals and nesting cavities; how lodgepole pine cones open only after a fire, bursting forth with the seeds of new life; even how trout depend upon the landslides that follow an intense wildfire to deliver woody debris to their streams, creating deep holes and hiding cover.
Native Americans understood and respected the role of fire, Hessburg said, and “were capable fire managers.” They learned to intentionally set fires to kill insect pests, create pastureland for their horses and to ward off massive uncontrollable summer fires by burning the grass and understory in spring and fall.
Historic landscapes of the Interior West were a patchwork of grasslands, widely spaced forests at lower elevations, sparsely vegetated south-facing slopes, thickly forested north-facing slopes, and rarely burned upper-elevation thickets.
But white settlers didn’t understand, or respect, the natural role of fire, Hessburg said. Almost immediately, they turned things upside down.
Cattle herds of up to 100,000 animals eliminated the grasslands that once carried fire across the landscape. Aggressive timber harvests took out the largest, thick-skinned trees, leaving behind the tiny diameter trees most susceptible to fire, insects and disease.
And when the Big Burn of August 1910 charred more than 2 million acres in two days, wiping out entire towns in northern Idaho and western Montana, the fledging Forest Service embraced a new national mission: firefighting.
It took 25 years, Hessburg said, but by 1935, the Forest Service was adept at “holding fires at bay,” effectively eliminating most fire from the national forests until the mid-1980s.
Then nature started correcting the balance, and wildfires began their return to the forests, growing ever larger and ever more difficult to control. Firefighters still controlled 98 percent of new starts, but those that got away started entering the “megafire” zone.
And humans weren’t finished with the disruptions, Hessburg said.
They started moving “outside of town,” into what is now called the wildland-urban interface. Just as fires started burning bigger and hotter, people started living in the forest.
“Homes in the WUI are hard to defend,” Hessburg tells his audiences. “Depending on the fire, from 50 to 95 percent of the suppression dollars are spent trying to protect homes. The per-home defense cost can easily exceed the value of the home itself.”
And the building continues.
Now comes what may be the largest, landscape-altering issue: climate change.
“Climate warming is having a huge effect on megafires,” Hessburg said, pointing first to the example of last May’s wildfire in Fort McMurray, British Columbia.
“It’s May. They’re halfway to the Arctic Circle, in the boreal forest. And that wildfire burned 2,400 homes and 1.5 million acres,” he said. “In its reports, CNN attributed it to the warming climate, and they were correct.”
David Peterson, a climate scientist at the University of Washington, has studied 100 years of fire history in the western United States. He believes the dry Intermountain West will experience two to three times more fire per year by mid-century.
Already, the wildfire season is 40 to 80 days longer.
“We are going to experience a tremendous change,” said Hessburg. “There will be a long period of adjustment. We have a lot of fuel buildup in these forests. We’re going to see intense crown fires that cover a lot of area.
“Every one of us is going to be affected. And every one of us has a responsibility to do something.”
Therein lies Hessburg’s call to action: “We need a shifting attitude from resisting fire to living with fire, because fire is part of our environment.”
Firefighters and land managers need a larger toolbox – and need their communities to embrace and participate in implementing the change, he said.
“Fire suppression alone is an incomplete solution,” he said.
Hessburg’s larger toolkit includes the widespread use of prescribed fire – intentionally ignited during the spring and fall; mechanical thinning of trees in forests where a lack of fire has created highly flammable thickets, designed to imitate the mosaic of a fire; homeowner actions to reduce the fire danger around their homes and on their private forests; and the use of “managed wildfire” – where firefighters “steer” the flames into areas that need burning.
Each of those tools, of course, has detractors and drawbacks.
“The greatest barrier to prescribed burning is the smoke it creates,” Hessburg said. “But you’re going to have smoke – it’s really a matter of whether you want it for a few days in the spring or fall, or for months in the summer at 10 times the concentration.”
Air-quality regulations prevent much of the needed prescribed burning, he said. “The regulations give wildfire smoke a pass; they consider it unavoidable. But prescribed fire is regulated as an avoidable nuisance. In my world, though, smoke is smoke.”
In his home state, Hessburg and others are pushing for – and succeeding in getting – exceptions to air-quality rules for springtime and fall burns. But they’ve only scratched the surface of what is needed to truly make a difference, he said.
Mechanical thinning is even more controversial, Hessburg said. “The abuses of the last century made us all gun shy about logging, so we threw out the baby with the bath water.”
No logging is no answer, though, he said.
Mike Peterson of Earth Matters provided the testimony. “I used to protest timber sales,” he said. “Now I see that thinning can result in smaller fires.”
“We are not suggesting thinning every acre of the forest,” Peterson said. “The right thing to do is to apply science, adapt the timber industry to the use of smaller-diameter trees, and start looking at this work on the landscape level.”
Homeowners have significant responsibilities on their own property, but often don’t act until fire is knocking at the door – which is too late.
“It’s not a matter of if, but a matter of when a fire will come,” said Sara Rolfs, who helps Hessburg present “Era of Megafires” and is a homeowner in the WUI in Wenatchee. “One spark is all it would take for many of us to lose everything.”
Twelve years after moving into their home, Rolfs and her family took action, hiring a forester to develop and implement a management plan that included thinning and prescribed burning.
“When I walk out there now, it is beautiful,” she said. “I have so much less fear. I feel so much safer because I’ve taken responsibility for my own land.”
On public land, the onus is on foresters and firefighters to start “managing” fires, Hessburg said, and they need to have the “social license” to actually let some of those previously suppressed fires burn – albeit in directions determined by firefighters’ actions.
“As communities, we are afraid to use managed wildfire because we are afraid the fire will get away,” he said. “And that is possible. But it’s also possible to get a wildfire to do some work for us in the forest.”
Managed wildfire, prescribed fire and forest thinning are all tough sells with the public, Hessburg conceded, when quizzed about “social license” by the audience.
But the alternative is more fire growth, more destroyed lives and community upheaval and the compounding problems created by global warming, he said.
Does each community have to experience a megafire before citizens and leaders are motivated to action? asked one member of the audience?
“I’m sad to say it took a lot of damage and a lot of lives broken before Wenatchee fully convened,” Hessburg said. “It took everybody realizing, ‘I can harden my home. I can work with my neighbors. We can work together to pull in every available resource. We can embrace prescribed fire and smoke and thinning – the larger toolkit.”
After multiple years of summer firestorms, “we are finally talking to each other,” Hessburg said. “What do we have to do? Who do we have to talk to right now? All the right people are finally talking to each other.”
“I hope it doesn’t take getting our butts kicked for that to happen,” he said. “I’d hope we are smarter than that. But the experience so far seems to indicate otherwise.”
“This is a social problem,” Hessburg said. “This is our problem.”
