What is one of the primary reasons the redwood trees were able to recover quickly after the CZU Lightning Complex Fire?
What is one of the primary reasons the redwood trees were able to recover quickly after the CZU Lightning Complex Fire?
- They have highly nutritious soil around them.
- They are damaged less in stronger winds.
- They store excess energy from leaf photosynthesis. (correct)
- They are constantly watered by natural springs.

Study Notes
Big Basin Redwood State Park Fire Recovery
- Big Basin Redwood State Park, California, is home to tall, ancient redwoods.
- The CZU Lightning Complex Fire in 2020 significantly damaged the park, burning 97% of it.
- Despite severe damage, the redwoods rapidly regrew.
- Research by Drew Peltier's team revealed two key resilience strategies.
Redwood Energy Storage
- Redwoods store excess energy produced by leaf photosynthesis.
- This stored energy sustains the trees when leaves are absent.
- Radiocarbon dating indicated stored energy was created as far back as the 1920s.
- The stored energy played a crucial role in the rapid regrowth.
Redwood Bud Tissue for Regrowth
- Redwoods possess bud tissue enabling leaf regrowth.
- The new sprouts originated from tissue nearly as old as the tree itself.
- Studies traced the tissue to the center of the tree's wood.
- This suggests the trees have an exceptionally long lifespan.
Redwood Fire Resilience
- Redwoods possess multiple adaptations for fire resilience.
- Height and thick bark are notable features.
- Stored energy and bud tissue for regrowth are two crucial adaptations discovered.
Park Recovery Outlook
- While full recovery will take years, signs of regrowth are widespread in affected areas.
- About 90% of the charred trees have significant regrowth.
