Giant sequoias have bark so resistant to fire that they survive forest fires.

Why it is true

Sequoia bark can be up to 60 centimetres thick and is poor in resin, which makes it hard to burn. In addition, the tree can heal the burnt areas. Regular fires are even beneficial, as they open space and release seeds.
