Discussion Genus name commemorates the Indian name Sequoyah (Sequoia) the inventor of the Cherokee alphabet. Oldest coast redwood is about 2,200 years old; many others in the wild exceed 600 years. Prior to commercial logging and clearing in the 1850's, this massive tree occurred naturally in an estimated 2.1 million acres along much of coastal California and the southwestern corner of coastal Oregon within the United States.
