Raging California wildfires threaten ancient redwood forests | Climate News

[ad_1]

Firefighters wrapped the roots of the world’s largest tree with a fire blanket in an attempt to rescue a huge ancient redwood forest from wildfires in California’s rugged Sierra Nevada Mountains.

Fire spokesperson Rebecca Paterson said that the huge “General Sherman” tree, giant forest museum and other buildings in Sequoia National Park are all wrapped up to prevent the possibility of intense flames. sex.

A wildfire last year killed thousands of sequoia trees, some of which are as high as high-rise buildings and are thousands of years old. Now, firefighters are using aluminum packaging and prescribed burns — deliberately setting up fires to remove other types of trees and vegetation that would otherwise contribute to the upcoming wildfire — to help protect the redwoods.

The wrapper can withstand intense heat in a short period of time. Federal officials say they have used this material in the western United States for years to protect sensitive structures from flames.

Historical droughts and heat waves related to climate change have caused Wildfires are harder to extinguish In the western United States, firefighters were on maximum alert for 65 days, setting a new record.The area has become a lot Warm and dry Over the past 30 years, and will continue to make the weather more extreme, wildfires more frequent and more destructive.

Near Lake Tahoe, some houses wrapped in protective materials survived a recent wildfire, while other nearby houses were destroyed.

The colony fire is one of two fires in Sequoia National Park and is expected to reach the giant forest of 2,000 sequoias within a few days. Fire spokesperson Katy Hooper said there was no significant increase in the fire on Thursday because a layer of smoke reduced the spread of the fire in the morning.

According to the National Park Service, the volume of the General Sherman tree is the largest in the world at 1,487 cubic meters (52,508 cubic feet). It is 84 meters (275 feet) high and has a ground circumference of 31 meters (103 feet).

Clay Jordan, director of Sequoia and Kings Canyon National Parks, emphasized the importance of protecting large trees from high-intensity fires at a briefing for firefighters.

The prescribed burns have been used in the redwood forests of the park for 50 years and are expected to help the giant trees survive by reducing the impact of flame arrival.

Patterson said: “The reliable fire history that stipulates fires in the area is a reason for optimism.” “I hope this huge forest can emerge unscathed.”

Giant sequoias adapt to fire, which can help them thrive by releasing seeds from their cones and creating open spaces that allow young sequoias to grow. But unusually strong fires caused by climate change may flood trees.

According to the National Park Service, the castle fire last year killed 7,500 to 10,600 large sequoias estimated by the study.

A national inter-departmental fire management team is responsible for extinguishing the 30 square kilometers (11.5 square miles) paradise fires and the 8 square kilometers (3 square miles) colonial fires closest to the woods. Burning vegetation and other flame-promoting fires have been carried out in the area Fuel action.

This week, the fire forced the evacuation of the park, and parts of Sanhe Town outside the main entrance are still being evacuated.

A statement from the Sequoia National Forest stated that in the south, fires on the Thule River Indian Reservation and the Giant Sequoia National Monument increased significantly overnight to more than 15 square kilometers (6 square miles) beyond the control of staff Fire.

The wind and fire, also triggered by lightning, have burned part of the Peroni redwood forest in the National Monument, and other forests have also been threatened.

The statement said: “Due to the inaccessible terrain, the preliminary assessment of the fire impact of the huge redwood trees in the forest will be difficult and may take several days to complete.”

The fire caused the Tulare County Sheriff’s Office to warn the communities in Ponderosa, Aspen, Aspen, Johnsondale, and Whitsett, as well as the Boy Scout camps, to evacuate if necessary.

Wildfires are the latest in a long summer fire that has burned nearly 9,195 square kilometers (3,550 square miles) of California land and destroyed hundreds of homes.
