Redwood tree adaptation
Redwood tree adaptation
Redwood trees have developed a remarkable adaptation to withstand the effects of wildfires. They store excess energy from photosynthesis for long periods, allowing them to survive and regrow even after extensive fire damage.
Energy storage in redwoods
Energy storage in redwoods
Redwood trees store excess energy from photosynthesis, which they can use to regrow after a fire, even if the fire has burned away their existing leaves. This stored energy can be decades old.
How old is redwood stored energy?
How old is redwood stored energy?
Radiocarbon dating revealed that the stored energy in redwood trees can be between 50 and 100 years old, meaning it was created and stored for future use decades ago.

Study Notes
Big Basin Redwood State Park Fire Recovery
- Big Basin Redwood State Park, California, contains some of the tallest and oldest redwoods.
- Redwoods can reach over 300 feet (91 m).
- Their thick bark typically protects them from wildfires.
- The CZU Lightning Complex Fire in 2020 burned 97% of the park, including ancient redwoods.
- Despite extensive damage, redwoods rapidly regrew new needles.
Redwood Regeneration Strategies
- Researchers investigated the redwoods' rapid recovery.
- Redwoods store excess energy from photosynthesis to sustain themselves during damage.
- Radiocarbon dating indicated this stored energy was as old as the 1920s.
- This stored energy allows redwoods to compensate for the lack of leaf production.
- Redwoods contain bud tissue that allows leaf regrowth.
- This bud tissue exists since the tree's inception.
- The tissue that allowed regrowth was traced back to the tree's center.
Redwood Resilience
- Redwood's resilience is attributed to thick bark, height, and unique energy storage and regrowth mechanisms.
- The full recovery of the park will take time.
- However, 90% of charred trees showed regrowth, suggesting a positive future.
