As a result of forest fires in California, up to 14,000 giant sequoias died in 2 years, which is almost 20% of all the largest trees on Earth.

LOS ANGELES. Lightning-triggered wildfires have killed thousands of giant sequoias this year, officials said Friday, adding a staggering two-year death toll, which account for nearly a fifth of the largest trees on Earth.

Fires in Sequoia National Park and the surrounding National Forest, which also bears the name of trees, have broken through more than a third of California’s groves and burned approximately 2,261 to 3,637 redwoods, which are the largest trees by volume. Fires in the same area last year killed an unprecedented number of between 7,500 and 10,400 of the 75,000 trees that grow in only 70 groves scattered along the western side of the Sierra Nevada.

Violent fires that have flared up strong enough and high enough to kill so many giant sequoias – trees that were once thought to be nearly fireproof – raise an exclamation point about the impact of climate change. The combination of global warming, causing hotter droughts, and centuries of suppression of fires that drowned out forests with dense undergrowth, led to wildfires that have become a death toll for trees dating back to ancient civilizations.

“The sobering reality is that we are witnessing another huge loss in a limited population of these iconic trees that are irreplaceable in many lives,” said Clay Jordan, Superintendent of Sequoia and Kings Canyon National Parks. “As impressive as these trees are, we really can’t take them for granted. Some action is needed to ensure that they are with our children, grandchildren and great-grandchildren. ”

California has had its largest fires in five years, with a record for the most area burned last year. So far, the second largest amount of land has been burned this year.

After fires at the SQF castle and complex last year took officials by surprise by destroying so many redwoods, emergency measures have been taken this year to save the largest and oldest trees.

General Sherman’s tree – the largest living thing on earth – and other ancient trees, which serve as backgrounds for photographs that often fail to convey the greatness of giant sequoias, were wrapped in a foil blanket.

A flame retardant gel, similar to the one used as an absorbent in baby diapers, has been dropped onto tree crowns that can be over 200 feet (60 meters) high. Sprinklers watered the trunks of water, and flammable substances were raked from the trees.

The measures spared the Giant Forest, the first grove of age-old trees in the park, but the measures could not be applied everywhere.

Much of the Suwani grove in the park burned down as a result of a massive fire at the Marble fork in the Kavea River runoff. The Grove of the Hungry Complex in Sequoia National Forest has been largely destroyed, judging by the counts of how many burned down with a high degree of severity.

“In 2013, a climate simulation was carried out at the park, according to which extreme fires will not threaten redwoods for another 50 years,” said Christie Brigham, head of resource management and science at the two parks. But that was at the beginning of what turned into a severe five-year drought that essentially broke the model.

During the drought of 2015, giant sequoias were lit in the park for the first time. Two fires in 2017 killed even more giant sequoias, serving as a warning of what was about to happen.

“Then there was a fire in the castle, and it was like, ‘Oh my God,’” Brigham said. “We’ve gone from a warning sign to burning hair. Losing 7000 trees in one fire is crazy. “
