Giant sequoia

Sequoiadendron giganteum


Giant sequoias are the world's largest trees by volume. They grow to an average height of 50–85 m (160–279 ft) and 6–8 m (20–26 ft) in diameter. Record trees have been measured to be 94.8 m (311 ft) in height and over 17 m (56 ft) in diameter. The oldest known giant sequoia based on ring count is 3,500 years old. Sequoia bark is fibrous, furrowed, and may be 90 cm (3.0 ft) thick at the base of the columnar trunk. It provides significant fire protection for the trees.


It occurs naturally only in groves on the western slopes of the Sierra Nevada Mountains of California.


For my 2,500th spotting I choose one of the most impressive organism I've ever seen... the Giant Sequoias that I finally saw last year (fulfilling a childhood dream)

Thank you Alice. I've been in PN since January 2012. It has been a life changing experience for me. Project Noah has opened my eyes to see a world that it was always there but I didn't know.
