About Redwoods
Three species of trees are commonly referred to as redwoods: California's coast redwood and giant sequoia, and China's dawn redwood.
For those who have had the chance to stand in a redwood grove, there are few life experiences that match it. Even if you have only ever seen a photo of the few ancient redwood forests left, it's hard to imagine life on our planet without these awesome and majestic places. We can all agree that there are some places on Earth that are so special that they are worth saving. That's why there is such strong support for protecting redwood lands.

Forests That Have Survived for Millions of Years
Redwoods get their common name from their bark and heartwood, the reddish-brown color of which stems from high tannin levels. Other chemicals found in the leaves, branches and bark give these trees a remarkable resistance to fungal disease and insect infestation. Their thick bark holds large quantities of water, which protects them from periodic, naturally occurring fires.
All three redwoods are descendents of a group of conifers (cone-bearing trees) that flourished more than 144 million years ago when dinosaurs roamed the Earth. At that time, the Earth's climate was warmer and more humid than it is today, so redwood species grew throughout North America, Europe and Asia. Over time and in response to an ever-changing environment, they retreated from most of their former range, and many once-abundant redwood species became extinct.
Successive ice ages, including the last one that ended about 10,000 years ago, have restricted the remaining redwood species to three small, distinct regions, each supporting one of the species. Each region is the only place in the world where you will find native populations of that …show more content…
These ecosystems depend on redwoods and support these trees. About 82 percent of the remaining ancient coast redwood forests is protected in parks and reserves; more than 90 percent of giant sequoia forests is protected in national parks and forests. Much work remains to ensure that future generations can enjoy these magnificent
