Antique Real Photo Postcard, circa 1930s. A giant Sequoia in Prairie Creek State Park in Humboldt County, California. Divided back, EKC stampbox, unused. Condition: Excellent. Comments: Sequoia sempervirens is the sole living species of the genus Sequoia in the cypress family Cupressaceae (formerly treated in Taxodiaceae). Common names include coast redwood, California redwood, and giant redwood. It is an evergreen, long-lived, monoecious tree living 1200-1800 years or more. This species includes the tallest trees living now on Earth, reaching up to 379 feet in height and up to 26 feet in diameter. Before commercial logging and clearing began by the 1850s, this massive tree occurred naturally in an estimated 2,100,000 acres along much of coastal California (excluding southern California where rainfall is not sufficient) and the southwestern corner of coastal Oregon within the United States. An estimated 95% or more of the original old-growth redwood forest has been cut down.
