Sequoiadendron giganteum responds to severe crown damage like its closest relative Sequoia sempervirens: by reiteration of new trunks from the main trunk and limbs. This tree in Calaveras Big Trees State Park is recovering from a lightning strike that shattered the main trunk, creating a decaying cavity 204 feet above the ground that is now home to a 7‐foot‐tall epiphytic dogwood tree.
