Dawn redwoods grow naturally today in south-central China.The Earth's last giant sequoias Giant sequoia are generally well able to protect themselves against their natural threats, allowing them to survive for thousands of years. They are too massive to be blown over in the wind, and their bark is thick and rich in tannins, which protect them against fire and insect damage. › redwoods › giant-sequoias

Why do redwoods not burn?
One very important adaptation for the coast redwood is its thick bark with deep grooves running vertically along the tree. It is this bark that gives the redwoods their fire-resistant characteristic. Older trees are able to survive fires because their bark is so thick and acts as a fireproof shell.
What happened to all the redwoods?
Giant old-growth redwoods were felled by pairs of “choppers” using double-bitted axes and long crosscut saws. Felling a single tree could take a week. After bucking, logs were initially moved by water to mills on the shores of Humboldt Bay. Logging railroads gradually took over part or all of log transport.
