Study Notes
Big Basin Redwood State Park
- Located in Santa Cruz, California, home to some of the tallest and oldest redwoods, exceeding heights of 300 feet (91 m).
- The thick bark of redwoods serves as natural armor, protecting them from wildfire damage.
CZU Lightning Complex Fire
- In August 2020, 97 percent of Big Basin Redwood State Park was burned by the CZU Lightning Complex Fire.
- Despite the intense fire, which scorched ancient redwoods, the trees exhibited remarkable resilience.
Recovery of Redwoods
- Within months post-fire, the charred redwoods began sprouting fresh green needles, showcasing rapid recovery.
- A research team led by Drew Peltier from the University of Nevada, Las Vegas, studied this impressive regrowth.
Energy Storage Strategy
- Redwoods can store excess energy from leaf photosynthesis, helping them survive during leaf loss.
- Radiocarbon dating of the stored energy revealed it to be between 50 and 100 years old, dating back to as early as the 1920s.
Regrowth Mechanism
- Bud tissue located within the trees enables the regrowth of leaves after damage.
- Examination of the sprouting areas indicated that these tissues originated from the tree's center, often from tissue nearly as old as the tree.
Additional Resilience Features
- Redwoods possess thick bark and extreme height, both contributing to their fire resilience.
- Approximately 90 percent of the charred trees show signs of regrowth, signaling a promising recovery for the ancient park.
- Full recovery of the park will take several years, yet the ongoing regrowth suggests a hopeful future.
