They Know How to Prevent Megafires. Why Won’t Anybody Listen?
The pattern is a form of insanity: We keep doing overzealous fire suppression across California landscapes where the fire poses little risk to people and structures. As a result, wildland fuels keep building up. At the same time, the climate grows hotter and drier. Then, boom: the inevitable. The wind blows down a power line, or lightning strikes dry grass, and an inferno ensues. This week we’ve seen both the second- and third-largest fires in California history. “The fire community, the progressives, are almost in a state of panic,” Ingalsbee said. There’s only one solution, the one we know yet still avoid. “We need to get good fire on the ground and whittle down some of that fuel load.”
Yes, there’s been talk across the U.S. Forest Service and California state agencies about doing more prescribed burns and managed burns. The point of that “good fire” would be to create a black-and-green checkerboard across the state. The black burned parcels would then provide a series of dampers and dead ends to keep the fire intensity lower when flames spark in hot, dry conditions, as they did this past week. But we’ve had far too little “good fire,” as the Cassandras call it. Too little purposeful, healthy fire. Too few acres intentionally burned or corralled by certified “burn bosses” (yes, that’s the official term in the California Resources Code) to keep communities safe in weeks like this.
Academics believe that between 4.4 million and 11.8 million acres burned each year in prehistoric California. Between 1982 and 1998, California’s agency land managers burned, on average, about 30,000 acres a year. Between 1999 and 2017, that number dropped to an annual 13,000 acres. The state passed a few new laws in 2018 designed to facilitate more intentional burning. But few are optimistic this, alone, will lead to significant change. We live with a deathly backlog. In February 2020, Nature Sustainability published this terrifying conclusion: California would need to burn 20 million acres — an area about the size of Maine — to restabilize in terms of fire.
