In California, Even Fire-Resistant Trees Need to Be Protected From Flames

Someplace between a childhood trip to Sequoia Nationwide Park and a school biology class, I latched on to a single reality about California’s big sequoias: They’re immune to wildfires.

These historical timber have survived for therefore lengthy as a result of they’d discovered a approach to coexist with a lethal menace. Or so I believed.

Final summer season, a single fireplace killed tens of hundreds of sequoias within the Sierra Nevada. And this month, blazes in and round Sequoia Nationwide Park are lapping on the bases of those huge timber, worrying the firefighters who’re scrambling to shield them.

The ever-increasing depth of fires in California has change into an excessive amount of even for the sequoias, which developed to survive — even thrive — in fires. The hazards prompted firefighters final week to wrap Common Sherman, believed to be the biggest tree on this planet, in flame-retardant foil in a bid to reserve it from flames.

Consultants say the fires that sequoias endured for hundreds of years have been largely low grade. Thick bark and sky-high crowns protected the timber from critical harm. Warmth from the flames even helped them reproduce by releasing seeds from their cones.

However now, California’s sequoia groves are coping with the implications of a century of fireplace suppression that has left forests dense with flammable vegetation. Drought and rising temperatures have killed different crops and turned them into kindling.

This has led to fires burning on an unprecedented scale. Between 2015 and 2020, two-thirds of the enormous sequoia groves throughout the Sierra Nevada have been scorched in wildfires, in contrast with 1 / 4 within the earlier century, in accordance to the Nationwide Park Service.

Sequoias could have tailored to fires, “however not to the confluence of modifications which have occurred over the previous 100 years,” Joan Dudney, a forest ecologist who has labored in Sequoia Nationwide Park, informed me.

Final summer season, the Fort fireplace killed off as many as 10,600 giant sequoias, or 14 % of the inhabitants, in accordance to the Nationwide Park Service. A few of the timber, which develop solely in California, have been charred from their trunk to their crown.

That has firefighters working to keep away from a repeat of final yr. They’ve been clearing brush from the bases of timber and swaddling them in reflective fire-resistant blankets which might be additionally used to shield properties in California.

As of Monday night, probably the most well-known timber in Sequoia Nationwide Park remained protected, together with Common Sherman. Firefighters and tree-lovers will nervously wait to see what Tuesday brings.
