Opinion by Joanna Nelson: We know what to do to save the giant sequoias
The Windy Fire blazes through the Long Meadow grove of giant sequoia trees near the Trail of 100 Giants in Sequoia National Forest on Sept. 21, 2021. Joanna Nelson is director of science and conservation planning for Save the Redwoods League and an expert in forest, coastal and fire ecology.
We knew that Red Hill was vulnerable. Decades of fire suppression throughout the Sierra Nevada have allowed the dense ingrowth of smaller trees and undergrowth that, when ignited, can bring fire into the crowns of the giant sequoias. The League had planned a prescribed burn for fall 2020 to reduce the risk of catastrophic loss, but the crew was called off to fight a wildfire.
First, we must act immediately to reduce the unnatural buildup of vegetation in the highest-risk groves. The Giant Sequoia Lands Coalition of government agencies, tribes and nonprofit organizations, including the League, has set a goal of treating 2,000 acres of the highest-risk groves before the 2023 wildfire season. This would include prescribed burning and/or removal of dense understory vegetation.
