Firefighters wrapped the roots of the world’s largest trees in a fire-resistant blanket in an attempt to save the famous virgin Sequoia grove from a wildfire burning Thursday in the rugged Sierra Nevada Mountains of California.
A giant General Sherman tree in the Giant Forest in Sequoia National Park, several other Sequoia, the Giant Forest Museum, and other buildings were wrapped in protection against the possibility of intense fire, fire spokesman Rebecca Patterson said. Said.
Aluminum wrapping can withstand intense heat for a short period of time. Federal officials say they have been using this material for several years throughout the western United States to protect sensitive structures from flames.shortly Lake tahoeSome homes, wrapped in protective material, survived a recent wildfire, but others nearby were destroyed.
A colony fire, one of the two burning in Sequoia National Park, was expected to reach the Giant Forest, a 2,000 sequoia forest, at some point in the next few days. It was unclear if that happened Thursday night. The fire did not grow significantly as the layer of smoke reduced its spread, said Katie Hooper, a spokeswoman for the fire.
It will come later Wildfire killed thousands of sequoiaLast year, some of the area was as tall as skyscrapers and thousands of years old.
According to the National Park Service, General Sherman’s tree is the largest in the world in volume at 52,508 cubic feet (1,487 cubic meters). It is 275 feet (84 meters) high and has a circumference of 103 feet (31 meters) above the ground.
Director Clay Jordan of Sequoia National Park and Kings Canyon National Park emphasized the importance of protecting large trees from high-intensity fires at briefings to firefighters.
A 50-year history of using open burning in the park (a fire intentionally set to remove other types of trees and vegetation that cause wildfires) Sequoia The grove was expected to help giant trees survive by reducing the effects of flames reaching them.
“The strong fire history of open burning in the area is an optimistic reason,” Patterson said. “Hopefully, a huge forest will emerge from this intact.”
Giant sequoias are adaptable to fire and can help them prosper by releasing seeds from the cones and creating clearings that allow young sequoias to grow.But fueled by the extraordinary strength of the fire Climate change— Can overwhelm the tree.
According to the National Park Service, it happened last year when Castlefire killed what was estimated to be a large Sequoia of 7,500 to 10,600.
Historical droughts and heat waves associated with climate change make it difficult to fight wildfires in the western United States. Scientists say climate change has made the region much warmer and drier, more extreme weather, and more frequent and destructive wildfires over the last three decades.
Inter-ministerial fire management teams across the country led efforts to combat 11.5 square miles (30 square kilometers) of paradise fires and 3 square miles (8 square kilometers) of colony fires closest to the orchards. .. Work was done in the area to burn vegetation and other fuels that could generate flames.
The fire forced the park to evacuate this week, leaving parts of the town of Three Rivers outside the front door evacuated on Thursday. A bulldozer was drawing a line between the fire and the community.
In the South, a fire at the Tree River Indian Reservation and the Giant Sequoia National Memorial expanded significantly to more than 6 square miles (15 square kilometers) overnight, and crew members did not contain it, according to a statement from the Sequoia National Forest. It was.
The wind fire, also initiated by lightning, burned on part of the National Monument Peirone Sequoia Gloves, threatening other gloves.
“Because of the inaccessible terrain, it is difficult to preliminarily assess the effects of fire on the giant sequoia trees in the grove, which can take several days to complete,” the statement said.
NS fire The Tulare County Sheriff’s Office has led the community of Johnsondale and the Boy Scout Camp, Camp Whitset, to warn them that they are ready to evacuate if necessary.
Wildfires are one of the latest in the long flames of summer, burning about 3,550 square miles (9,195 square kilometers) in California and destroying hundreds of homes.
Crew members have limited ground access to colony fires, and the terrain around the paradise fires is extremely steep, so they are completely protected and both fires require large amounts of aerial water and flame-retardant water droplets. was. The two fires were managed together as a KNP complex.
