Giant Sequoia Fire History in Mariposa Grove Abstract

ABSTRACT - We reconstructed a 1,438-year history of wildfire in the Mariposa Grove of giant sequoia Sequoiadendron giganteum. Partial cross sections were taken from 18 dead fire-scarred trees, and tree rings and fire scars were dated. The resulting master fire chronology shows that fires recurred at intervals ranging from 1 to 15 years. Changes in fire frequency on time scales of centuries are also apparent. This fire history documents the long-term importance of fire in sequoia-mixed conifer ecosystems and illustrates the temporal variability of fire regimes.
Did You Know?
Sometimes you will see sequoias in a straight row. This may happen because sequoia seeds prefer mineral-rich burned ground. When a fallen log burns long and hot, it leaves a strip of bare mineral-rich soil — an ideal place for new sequoias to grow. Years later, we see a line of sequoias!
