Wildfires torched up to a fifth of all giant sequoia trees

Wildfires torched up to a fifth of all giant sequoia trees --Wildfires last year killed 7,500 to 10,400 of giants sequoias | 20 Nov 2021 | Lightning-sparked wildfires killed thousands of giant sequoias this year, leading to a staggering two-year death toll that accounts for up to nearly a fifth of Earth's largest trees, officials said Friday. Fires in Sequoia National Park and surrounding Sequoia National Forest tore through more than a third of groves in California and torched an estimated 2,261 to 3,637 sequoias, which are the largest trees by volume. Nearby wildfires last year killed an unprecedented 7,500 to 10,400 giant sequoias that are only native in about 70 groves scattered along the western side of the Sierra Nevada range. Losses now account for 13% to 19% of the 75,000 sequoias greater than 4 feet (1.2 meters) in diameter.
