Giant Redwood Trees Endured Frequent Fires Centuries Ago

A prescribed burn was conducted in July 2001 in the Giant Forest of Sequoia National Park. The giant redwoods endured frequent fires from the yeas 800 to 1300. Human activity reduced fires in recent decades but now scientists have reintroduced fire to the ecosystem. Credit: Tony C. Caprio

Ancient trees pack a record of ancient events. And now scientists have used 52 of the world's oldest trees — giant sequoia redwoods in California's western Sierra Nevada — to show that the region was plagued by drought and fire from the year 800 through the year 1300.

Scientists reconstructed a 3,000-year history of fire by dating fire scars on the inland sequoias (Sequoiadendron giganteum) in the Giant Forest of Sequoia National Park. Individual giant sequoias can live more than 3,000 years.
