The fires at the KNP complex have engulfed the heart of the Sequoia country in western America.
The fire, which reached the edge of the Giant Forest in Sequoia National Park in California, did not damage four famous giant Sequoia, U.S. authorities said, adding that trees could be damaged due to the fire.
Four Guardsmen, a team of trees that created a natural entrance to the ancient forest road, successfully saved the KNP complex from fire by removing nearby vegetation and wrapping fire-resistant material around the base of the tree, the fire management team said in a statement Sunday.
The drought associated with climate change is hardening wildfires in the western United States and has killed millions of trees in California alone. Last year a wildfire killed thousands of sequoias, some taller than thousands and thousands of years old.
The KNP complex fire started with two lightning-like flames that combined to burn more than 96 square kilometers (37 square miles) in the heart of Sequoia in the western opera of the Sierra Nevada mountain range.
The full extent of the damage was not immediately known in the Sequoia National Forest’s Giant Sequoia National Memorial area and a few more Sequoia groves reached by a separate fire, The Windy Fire, in the Tul River Indian Reservation.
A portion of The Land Meadow Grove, along with Peyron and Red Hill Grove, burned down the path of the 100 Giants.
Thanh Nguyen, a spokesman for the fire command, said it had been confirmed that part of a huge sequel had been burned along the trail.
Firefighters were working to limit the damage to the giant sequoia in the grooves of hose and watering helicopters, where other types of trees are also present.
Sequoias have adapted to the fire and may benefit if the intensity of the fire is low.
The wind blaze burned more than 101sq km (39sq miles) and was only 4 percent under control.
The KNP complex was forced to evict Sequoia National Park last week and much of the adjacent Kings Canyon National Park was closed on Sunday. In areas that were still open, visitors were warned about hazardous air quality due to smoke.
A large area of Northern California was under a red flag warning for extreme fire hazards due to a dry coastal wind on Monday.
The warning did not extend as far as Southern California, but forecasters said there would be weak Santa winds and significant warming – increasing the risk of wildfires.
According to the California Department of Wildlife and Fire Protection, more than 7,000 wildfires in California this year have damaged or destroyed more than 3,000 homes and other buildings and burned 7,770sq km (3,000sq miles) of land.
