Last year, California’s Castle fire may have killed off ten to 14 percent of the world’s giant sequoias, reports Joshua Yeager of the Visalia Times-Delta.
The tally of dead trees comes from a new draft report that used satellite imagery, forest modelling and surveys to revise initial estimates of how many titanic trees were lost when flames ripped through parts of Kings Canyon and Sequoia National Parks. That initial estimate was around 1,000 dead sequoias, but now scientists with the National Park Service and U.S. Geological Survey (USGS) suspect between 7,500 and 10,600 mature trees may have died, reports Kurtis Alexander for the San Francisco Chronicle.
Per the Chronicle, among the fallen is the planet’s ninth-largest giant sequoia, nicknamed the King Arthur tree. Sequoias can live for thousands of years and grow to more than 250 feet tall and measure 30 feet in diameter, per the Chronicle.
“The whole thing is surprising and devastating and depressing,” Christy Brigham, chief of resources management and science at Sequoia and Kings Canyon National Parks and lead author of the report, tells Alex Wigglesworth for the Los Angeles Times.
Researchers were surprised by the death toll because of how adapted to living with fire giant sequoias are. Per the LA Times, sequoia bark can be two feet thick and their cones only release their seeds to spawn the next generation when they’re toasted by low intensity fire.
Brigham tells the LA Times that losing so many mature trees to a single fire signals the fact that climate change and a century of fire suppression have rewritten the rules that once governed the sequoia’s domain.

TULARE COUNTY — A Bay Area conservation group has signed a deal to purchase the world’s largest privately owned giant sequoia forest, a primeval landscape in California’s Southern Sierra Nevada with massive trees that soar 250 feet tall, span up to 80 feet around at their trunks and live for more than 2,000 years.
The 530-acre property, known as the Alder Creek, is roughly the same size as Muir Woods National Monument in Marin County. Located in Tulare County 10 miles south of Sequoia National Park, it is home to 483 massive trees that are larger than six feet in diameter — four more trees than the famed Mariposa Grove at Yosemite National Park.
“This is probably the most-coveted sequoia conservation opportunity in a generation,” said Sam Hodder, president of Save the Redwoods League, a non-profit group based in San Francisco that has agreed to pay $15.6 million to purchase the property.
“It’s not any single tree,” he said of the landscape, which eventually will be open to the public. “This is an alpine landscape covered with iconic, breathtaking, cinnamon-barked trees that are surrounded by pastures. It is such a superlative representation of nature. This is the prize. This is the best of what’s left. It’s a very special place.”
The league, founded in 1918, signed a purchase agreement with the Rouch family, who has owned it since the 1940s. The family’s patriarch, Claude Albert, bought the land for its logging potential just before World War II, said his grandson, Mike Rouch, of Fresno.
“When they bought the property there was not even a road to it,” he said. “They had to ride horses.”
Over the generations, the family cut down sugar pine, white fir, red fir and other trees to make framing lumber for houses and other products. But they left the massive sequoias largely untouched.

After a three-year restoration project, the Mariposa Grove of giant sequoias in Yosemite National Park has reopened, with less asphalt and more concern for the health of the trees.
YOSEMITE NATIONAL PARK, Calif. — John Muir, the naturalist who was most at home sleeping outdoors on a bed of pine needles in the Sierra Nevada, called giant sequoias the “noblest of God’s trees.”
For three years, some of the most striking examples of these towering marvels were off limits to visitors in Yosemite National Park. After a $40 million renovation — the largest restoration project in the park’s history — the Mariposa Grove, a collection of around 500 mature giant sequoias, reopened last week.
What Muir called a “forest masterpiece” is now back on display.
The renovation addressed a problem that the park has struggled with for years. On the busiest summer days, more than 7,000 cars may converge on the park, which is about a four-hour drive from San Francisco. The gridlock they create amid the stunning chutes of water running down the steep granite slopes of Yosemite’s glacier-carved valley results in a kind of drive-by naturalism that frustrates many.
