Thunderstorms have killed thousands of giant sequoia and killed up to one-fifth of the planet’s largest trees for an astonishing two years, officials said.
Fires in Sequoia National Park and the surrounding national forests are also named after the trees. California Burned an estimated 2,261 to 3,637 sequoia. A fire in the same area last year killed an unprecedented 7,500 to 10,400 of the 75,000 trees.
Sequoia is the largest tree in volume and grows only in about 70 orchards scattered along the western side of the Sierra Nevada Mountains. They were once thought to be nearly fire resistant. The fierce fire, which was hot enough to kill so many giants and burned high, puts an exclamation mark on the effects of the climate crisis.
Clay Jordan, director of Sequoia National Park and Kings Canyon National Park, said: “These trees are spectacular, but we can’t really take them for granted. Some actions to ensure they are for our children, grandchildren, and great-grandchildren. Is required. “
The combination of a heated planet that caused a hotter drought and a first-century fire extinguishing that suffocated forests with thick undergrowth fueled the flames ringing the death bells of trees dating back to ancient civilizations.
California had the largest fire in the last five years and set a record for most acreage last year. So far, the second most land is burning this year.
After last year’s castle and SQF complex fires wiped out many sequoia and surprised officials, special steps were taken this year to save the largest and oldest tree.
General Sherman Tree and other ancient trees, the largest creatures on the planet, were wrapped in foil blankets. A type of flame-retardant gel similar to that used as an absorbent for baby diapers was dropped on a canopy that could exceed 200 feet (60 meters) in height. Sprinklers watered the trunk and combustibles were scraped from the trees.
The measures escaped the Giant Forest, the best orchard of ancient trees in the park, but the measures could not be deployed anywhere.
Most of the Swany groves in the park were burned in an extreme fire at the Marble Fork in the Cavea River drainage channel. The groves of the Sequoia National Forest hunger complex were largely destroyed, based on estimates of how severe and how much they burned.
In 2013, the park conducted climate modeling that predicted that extreme fires would not endanger Sequoia for another 50 years, said Christy Brigham, head of resource management and science for the two parks. .. But it was essentially the beginning of a punishing five-year drought that broke the model.
During the 2015 drought, a giant sequoia was set on fire for the first time in the park. Two fires in 2017 killed an even bigger sequoia and acted as a warning of what was to come. “Then a castle fire broke out, and it was like” Oh, my god, “” Brigham said. “We lit our hair from the warning sign. It’s strange to lose 7,000 trees in a single fire.”
Forest crews are checking how many trees have died when a thunder struck on September 9 and the windy fires of the Sequoia National Forest and the park’s SQF complex ignited. Therefore, the complete mortality rate from last year’s fire is not yet known. Brigham said.
Not all news from the quote was dark.
Twenty-seven orchards burned and many trees were incinerated, but there was plenty of low-intensity fire needed for the redwood to breed, vegetation was wiped out, heat opened cones and spread seeds. I can.
However, it may not be reproducible in areas where the fire has become so hot that the seeds have been killed. For the first time in the park, we are considering planting saplings to protect the seeds.
“I’m not ready to give up the giant sequoia,” Brigham said.
