In 2005 while a freshman California Assemblyman, I had the chance to visit Northern California and meet with the forest product industry professionals who grew, managed, and harvested trees on private and public lands. They told me of a worrisome trend started years earlier where both federal and state regulators were making it more and more difficult for them to do their jobs. As a result, timber industry employment gradually collapsed, falling in 2017 to half of what it was 20 years earlier, with imports from Canada, China, and other nations filling domestic need.

As timber harvesting permit fees went up and environmental challenges multiplied, the people who earned a living felling and planting trees looked for other lines of work. The combustible fuel load in the forest predictably soared. No longer were forest management professionals clearing brush and thinning trees.

The result was accurately forecast by my forest management industry hosts in Siskiyou County in 2005: larger, more devastating fires—fires so hot that they sterilized the soil, making regrowth difficult and altering the landscape. More importantly, fires that increasingly threatened lives and homes as they became hotter and more difficult to bring under control. //

In the 1850s and 1860s, the typical Sierra landscape was of open fields of grass punctuated by isolated pine stands and a few scattered oak trees. The first branches on the pine trees started about 20 feet up—lower branches having been burned off by low-intensity grassfires. California’s Native American population had for years shaped this landscape with fire to encourage the grasslands and boost the game animal population. //

Some two decades ago, California produced so much wood waste from its timber operations, including brush and small trees from thinning efforts, that the resulting renewable biomass powered electric generating plants across the length of the state. But cheap, subsidized solar power, combined with air quality concerns (wood doesn’t burn as cleanly as natural gas) and a lack of fuel due to cutbacks in logging, led to the closure of many biomass generators. What used to be burned safely in power generators is now burned in catastrophic fires. Including the growing capture and use of landfill methane as a fuel, California’s biomass energy generation last year was 22% lower than it was 25 years before.
