Devastating fires over the last three years in California have endangered the limited number of giant sequoias to the point where scientists are cloning the huge trees and planting them farther north where climate change may produce suitable growing conditions.
Preliminary surveys found that in a two year period, 2020 and 2021, almost 20 percent of all giant sequoias in their natural range over four feet in diameter were killed by fire (and neglect) or will die in the next few years. In 2020, 10 to 14 percent of the entire Sierra Nevada population of giant sequoia trees over 4 feet in diameter were killed in the Castle Fire. Early estimates after two fires the following year, the KNP Complex and the Windy Fire, 2,261 to 3,637 sequoias over four feet in diameter were killed or will die within the next three to five years.
At this rate, with this climate, we could lose the rest of these massive trees in just a few years.
A team of expert horticulturists is using cloning technology to replant redwoods and sequoias and save their genetic material.
