Sunday’s Big Basin fire “part of the natural process,” State Parks scientist says

BIG BASIN — Embers from a burning redwood root, a remnant of August’s CZU Lightning Complex fire, found their way to the surface in Big Basin State Park, and reignited according to Cal Fire officials, resulting in a 6.5 acre fire which sparked on Sunday.

Locals and outdoor enthusiasts alike held their breath over the weekend, but crews contained the fire, which burned well within the interior of the park, according to Joanne Kerbavaz, a senior environmental scientists with California State Parks Santa Cruz District.

These types of small blazes can actually be beneficial to Santa Cruz forests, explained Kerbavaz.

“This really is part of the natural process, and there is value in having natural fire,” Kerbavaz said.

Small, slow-moving fire that creeps along the forest floor can have a rejuvenating effect, particularly in ecosystems that are fire-adapted.

“Anytime there’s a fire on the ground, it has the opportunity to remove excess fuel and to create new space for germination of seeds and increased growth of existing trees,” Kerbavaz said.

According to a 2005 UC Berkeley research paper, this type of healthy fire was common in the Santa Cruz Mountains prior to the 19th century.

Prescribed burning, a tool wielded by Indigenous peoples living in the Santa Cruz region, was banned by Mexican and European settlers around that time. That burning was a strategy to manage lands, grow foods, medicines and materials, according to Amah Mustun Tribal Band Chairman, Valentin Lopez. It also kept fires like the CZU Complex from burning, and is a spiritual practice.

Burns prevent build up of fuel, which in turn, prevent wildfires that can result in loss of life, or property.

Kerbavaz wasn’t surprised at the CZU Lightning Complex fire reignition — there have been a few smaller fires that have sparked the same way in Big Basin since the August blaze, she said.

“This is the reality in the redwood forest, we knew it was possible for fire to linger in downed logs and trees, themselves,” Kerbavaz  said.

In September 1904, embers from a fire that burned in Big Basin reignited in a redwood stump twice: seven months after the blaze, and another reburn occurred 14 months later in November 1905, according to the Mountain Echo newspaper.

“Looking back at reports in the 1904 fire in Big Basin, it was the same thing, there were accounts in the press of the public being surprised at the rekindling event months and months after the fire,” Kerbavaz said.

Cal Fire CZU San Mateo-Santa Cruz Unit Chief Ian Larkin echoed Kerbavaz, saying the small blaze consumed leaf litter and light debris that were shed by fire-damaged trees over the winter months.
