Factual summary: - There are only three remaining redwood species in the world (China's Dawn redwood, sequoia, and West coast) - A mature redwood adds, on average, a ton of wood to its mass every year. - 96% of West coast redwoods' habitat has been lost. - "Albino" redwoods exist that make no/little chlorophyll, surviving by alternate means. - Some West coast redwood trees are 2,200 years old and reach up to 400 feet in height. - Tall redwoods exert two million pounds of hydraulic force raising water to upper leaves. - A fallen redwood was weighed at 3,630 tons, more than 16 times heavier than the Statue of Liberty. - The marbled murrelet (Brachyramphus marmoratus), an endangered seabird lives in the canopy. Its flight speed is up to a hundred miles an hour. The first nesting site was discovered in 1974 and nesting habits were completely unknown until then. - Redwoods can endure fire, and appear to be evolving for greater heat endurance.
