(CNN) — The KNP Complex Fire in California has reached a “small area” of the Giant Forest in Sequoia National Park, home to some of the world’s largest trees, according to fire officials.
The KNP Complex Fire was 0% contained as of Saturday. Fire officials expected winds to pick up in the area Sunday, prompting a red flag warning that will remain in effect through the day.
“Crews are preparing for changes and possible significant increases in fire activity,” the update Saturday said.
Last year, between 7,500 and 10,600 mature giant sequoias were destroyed in the Castle Fire — about 10 to 14% of the world’s population of mature sequoias — according to a report by the National Park Service published in June.
Officials last week were working to mitigate the treat of the fire. But this time the wildfire is burning in places where the National Park Service has no history of fires ever burning, a park official told CNN, meaning there’s a lot of overgrowth that could fuel the burn.
“We basically told the fire crews to treat all our special sequoias like they were buildings and wrap them all up, and rake all the litter away and roll away the heavy logs,” said Christy Brigham, chief of resource management and science for the Sequoia and Kings Canyon National Parks.
