What is cool about coastal redwoods is that they can survive all of their branches being burned off (i.e., a tree topping fire). The redwood trees in the Oakland fire were just logs in the sky after the fire and now the ones that were not cut down look quite nice. You can see the sprouts coming out of the redwoods left in place after the Santa Rosa fire. And those were just young redwoods (<100yr old). The ancient redwoods have much thicker insulating bark layers and even some insulating bark on some of the larger branches. It takes a lot of heat for a long time to heat up a 12ft diameter insulated redwood tree enough to kill it.
