How trees survive after fires

We spent awhile looking at some of the fire damaged trees. Some were definitely burnt to a crisp, but actually many looked like they might survive. We did some research and found that whilst pine trees are very flammable, they have a number of adaptations they use to survive. These include thick bark which doesn't catch fire as quickly and so can protect the inside living tissue. They also often drop lower branches as the tree grows older, which helps fire from climbing up and burning the green needles further up. They also typically have an extensive root system to allow for resprouting after fire, which we definitely saw evidence of.
