Redwood trees are ancient. They carry ancient tails of turmoil. Now, however, scientists have proven that giant sequoia redwoods in California's western Sierra Nevada were ravaged with fires. This had taken place from 800 A.D. through 1300 A.D.
Scientists dated fire scars, or assigned time periods to marks made by fires, in the Giant Forest of Sequoia National Park. You see, one sequoia redwood can live for more that 3,000 years.
The Medieval Warm Period, from 800 to 1300 had the most fires in these years that were studied. It is not well known about the Sierra area being warm, but the slopes sure were fiery. In this situation, there is a very distinct relationship between forest fires and drought. Droughts are warm, and especially dry.
Scientist predict that climate change will make the trees live in a warm, dry environment. Also, other studies found that not enough coastal fog in California could disrupt these ancient trees.
