Raging wildfires in California have reached the Giant Forest, an iconic grove of more than 2,000 giant sequoia trees and are threatening thousands of homes.
Firefighters are using controlled burns to remove dry shrubs that help the fire spread more rapidly to the trees.
The tree bases have been covered in foil paper and sprinkler systems have been installed in-between each tree. Officials are trying to keep the area wet to prevent the fire from spreading to treetops.
Authorities confirmed that at least two of the fires started due to lightning strikes, but a third is under investigation.
