Natural fires occurred approximately every 5-15 years in sequoia groves. Sequoias thrive in a forest with frequent fire which opens the canopy for this sun-loving tree and clears the ground so there tiny seeds can germinate and grow.
Giant Sequoias Yield Longest Fire History From Tree Rings
California’s western Sierra Nevada had more frequent fires between 800 and 1300 than at any time in the past 3,000 years, according to a new study based upon tree-ring research.
The report, Multi-Millennial Fire History of the Giant Forest, Sequoia National Park, California, USA, was published in the electronic journal Fire Ecology in February.
A 3,000-year record from 52 sequoia trees show that California’s western Sierra Nevada was droughty and often fiery from 800 to 1300, according to the study led Thomas Swetnam, Director of the University of Arizona Laboratory of Tree Ring Research.
Scientists can crossdate multiple samples (no live trees were sampled) by matching…
