Coast redwood

Sequoia sempervirens, or coastal redwood, is a magnificent, monoecious evergreen tree that can live very long (1,800+ years) and reach up to 379 feet in height. It occurs naturally along the coast of California and the southewestern coast of Oregon. It is an excellent tree for lumber, so much that after the logging spree of the 1850s, it is estimated that 95% of old growth redwoods were cut down. Its crown is conical and it has very thick bark (up to 12 inches). The needles are arranged mostly in two dimensions, less than one inch long, and have dual white lines underneath. The coast redwood and conveniently has both seed and pollen cones on the same tree, making it self-reproducing. Growth however is low, with seed viability below 15% germination.
