Coast redwoods occupy a narrow strip of land along the Pacific coast of North America; from the most southerly grove in Monterey County, California to groves that exist in extreme southwestern Oregon.
It is an evergreen, long-lived, monoecious tree living 1200–1800 years or more. This species includes the tallest trees on Earth, reaching up to 379 feet (115.5 m) in height and up to 26 feet (7.9 m) diameter at breast height. Before commercial logging and clearing began by the 1850s, this massive tree occurred naturally in an estimated 2,100,000 acres (8,500 km2) along much of coastal California. It is estimated that more than 95% of the original old-growth redwood forest has been cut down for timber.
