In 2020, 9,000 fires scorched more than 4 million acres of California, a record-breaking year, reported Alejandra Borunda in National Geographic. Fires burned through homes and oak forests, grasslands and pines — and also through patches of giant sequoias and coast redwoods, respectively the most massive and the tallest trees on earth.
Giant sequoias are not the oldest living trees, but some have been growing in Sierra Nevada forests for more than 3,200 years. They are found in 68 groves on the Sierra's western flank. The...

Five of California's six largest fires have occurred in 2020, reported Julie Cart in CalMatters.
“There is a collective sensation that we are reaching a tipping point,” said Lenya Quinn-Davidson, a fire specialist with the University of California Cooperative Extension. “This year was not just the fluke burning horrifically. This is 3.2 million acres of fire that burned in a month.”
Quinn-Davidson is based in Humboldt County, with typically rainy, foggy redwood forests. However, she said, the forests don't resemble their former...

While many California communities have been left without power, UC Cooperative Extension fire scientist Lenya Quinn-Davidson worries that last year's Camp Fire has put too much focus on utility companies as the cause of fires, reported Tara Law in TIME.
Major fires are sometimes caused by utilities, but there are many other potential causes, including lightning, arson and sparks from dragging chains. All of these factors, are compounded by "lack of fuel management, poor land-use planning, and homes that aren't ready for fire and aren't resilient to fire," Quinn-Davidson said.
Power outages can...

The Federal Government has proposed spending $55 to $192 million to clear large swaths of land in the Western U.S. to create fuel breaks that slow the spread of wildfire, reported Brady McCombs of the Associated Press. The fuel breaks will be managed by the Bureau of Land Management in Idaho, Oregon, Washington, California, Nevada and Utah.
Fuel breaks are a useful tool if used along with other wildfire prevention methods that can keep firefighters safer and potentially help out in broad scopes of land because they are long and thin, said Lenya Quinn-Davidson, the area fire...
