Giant Sequoia
Sequoiadendron giganteum
Also known as: Giant Redwood, Sierra Redwood, Wellingtonia
Giant Sequoia is the world's most massive tree species, native to California's Sierra Nevada. The wood is lightweight, easy to work, and moderately durable. Commercial harvest is limited as most groves are protected; wood comes from managed stands or salvaged logs.
