Prescribed burns aid giant sequoia survival

A July 26 study by UC Davis researchers showed that planned controlled burns dramatically increased the odds of giant sequoias surviving recent wildfires, saving roughly 1,900 trees in the 2020 Castle Fire and the 2021 KNP Complex Fire and estimating that broader use could protect an additional 4,000 trees.

A follow‑up report on July 29 confirmed these findings in collaboration with the U.S. Geological Survey and the National Park Service, emphasizing that low‑intensity prescribed fires are now a key management tool in Sequoia and Kings Canyon National Parks. The same release cited separate UC Berkeley research warning that climate change is already raising temperatures in California’s national parks and could multiply wildfire frequency, pushing vegetation zones upslope and expanding fire risk into historically less‑burned areas.

Together the snapshots portray growing scientific consensus that prescribed burning is essential for preserving giant sequoias, even as a warming climate threatens to intensify future fire challenges.
