We know that fire is an integral part of forest ecosystems. We know that our previous policy of “complete fire suppression” is a recipe for disaster. And yet parks still screwed up and was at least indirectly responsible for the blaze that eliminated most of the structures in the park. And one of the park’s environmental scientists saw it coming:
Nine months before Big Basin Redwood State Park suffered its worst fire in recorded history, one of the park’s environmental scientists gave a podcast interview revealing that a prescribed burn had not taken place within the park in three years… “Given the right conditions, we’re poised to have catastrophic wildfires all over California,” says [Portia] Halbert, who works for the Santa Cruz District of the California State Park System.
And it looks like bureaucracy was to blame. The government doesn’t have the fortitude to publicly stand up and say that being overly cautious regarding moisture, wind, and air quality has its own risks, the consequences we are seeing right now.
The fact that prescribed burns have not taken place in Big Basin for years is a surprise even to people who work for the park and partner organizations.
“We haven’t done a large burn in Big Basin in the last three years because the weather hasn’t lined up,” Halbert says in the podcast. She brings up other bottlenecks to prescribed burns including permitting issues, staffing, and a short — or nonexistent — window for favorable weather conditions.
Big Basin burns can only happen in the fall. The fuel, composed of vegetation and plant material that burns easily, can’t be too wet or too dry. There must be some rain, but not too much. Winds must be blowing away from populated areas. If the winter rains come, the opportunity is gone.
Strict guidelines established by the Clean Air Act and enforced by air-quality districts can also prevent burns. “It’s a great thing to protect public health, but it makes it challenging for us to actually implement prescribed fires,” Halbert says.
For these reasons and more, prescribed burns have been underutilized not only in Big Basin but throughout California, according to a recent Stanford study published in Nature.
