With firefighters having rushed to quell blazes as soon as they could, forests have been transformed into fuel-stuffed tinderboxes – with disastrous consequences when fires inevitably get out of control.
Forest managers now understand what Native Americans long knew – controlled burns are key to successful management.
Around 20 different organizations are now aiming to burn a total of 160,000 hectares a year by 2025.
But, says Jared Childress of the Central Coast Prescribed Burn Association, which is involved in the Santa Cruz controlled fire, that figure is nowhere near enough.
“We need to scale this up,” he said. “We need to be doing burns exactly like this, all throughout California, throughout the fall, throughout the winter, throughout the spring, even in early summer.
“We’re nowhere near the level that we need to be, both ecologically and also from changing the wildfire dynamic.”
“ARTFUL”
At present, the windows granted by the authorities for these operations remain very narrow.
The nervousness to fully embrace a practice that many land managers see as vital could stem from perceived risk.
While most controlled burns go off without a hitch, they occasionally go wrong – like one in New Mexico in the autumn of 2022 that ended up destroying hundreds of homes.
Lenya Quinn-Davidson, a specialist in controlled fire at the University of California, says it is a specialised area,
“Prescribed fire is a very artful, thoughtful practice,” she told AFP.
“So it’s not the kind of thing where you can just hire someone and then they can come in and just start prescribed burning, you have to really have a lot of training and experience.”
Nonetheless, the amount of land burned each year has to rise dramatically, if the catastrophic wildfires that have torn through parts of California and other western states in recent years are to be avoided.
“There have been some historical reconstructions of fire regimes and pre-European settlement, (showing) anywhere from four to 11 million acres burned every year” in California, Quinn-Davidson said.
In comparison, “our landscapes are starved for fire”.
In the forest outside Santa Cruz, ecology student Ian Cook was among those learning how best to use this powerful tool, working on weather reports to help teams understand how the flames will move when they are set.
For him, it’s a huge collaborative effort that is needed to seize control of the issue and to try to prevent the vast destructive blazes of recent years.
“We’ll have to work together,” he says.
“Because this is a problem that affects all of us.”
