Sequoias are among the oldest and largest trees in the world: The giant sequoia (Sequoiadendron giganteum) can live for over 3,000 years and grow to be more than 300 feet tall. The largest known living tree, named General Sherman, is a giant sequoia and is considered the largest tree by volume on Earth.
Sequoia trees have fire-resistant bark: The bark of sequoia trees can be up to 3 feet thick and is rich in tannins, which makes it highly resistant to fire. This adaptation helps protect the trees from wildfires, allowing them to survive in fire-prone environments.
