Only 5% of the world’s old-growth redwoods exist today. Unfortunately, the other 95% of redwoods were cut down. Of the 5% remaining, 85% are protected in parks and reserves.
The Northern California Coast Redwoods are the world's tallest living tree on earth. The Park features the first, second, third, and sixth tallest known trees in the world along with 40 miles of rugged coastline, grass prairies and oak woodlands. Redwoods can grow to 350 feet or more, with a base diameter of about 20 feet. Their root systems are broad and shallow, from only a few inches to six feet underground. The oldest coast redwoods are about 2,000 years old and show no signs of dying out. Similar to Sequoias, they resist insects, fire and rot to a remarkable degree, and their vigor in sprouting back when cut or badly burned is an important factor in their longevity.
