The coast redwood, also called the California redwood, is the tallest living thing in the
world. It also grows
to great
volume. One grove of trees in Humboldt Redwoods State park contains the largest measured concentration of
living
material, or biomass, in the world.
The current natural range of the coast redwood is confined to a coastal strip about 450 miles long from the
southwest
corner of Oregon to southern Monterey county. This strip is 5 to 35 miles wide and covers approximately 2.2
million
acres. Old growth redwoods occupy about 200,000 acres, most of which is in state and national parks. About
600,000 acres
of coast redwood habitat are in commercial timber production.
Redwood is named for the color of its bark and heartwood. The high tannin content of the wood gives the
trees
remarkable resistance to fungus, diseases, and insect infestations, reasons why redwood lumber is so
desirable.
