Redwood Tree Wildfire Resilience

Play an AI-generated podcast conversation about this lesson

How do redwood trees utilize stored energy reserves to recover after a wildfire, according to the research findings?

By using stored energy to produce new sprouts and needles when leaves are absent due to fire damage. (correct)
By releasing stored energy as heat to protect the tree from further fire damage.
By converting stored carbohydrates directly into bark to repair fire damage.
By utilizing stored energy to initiate photosynthesis in the remaining leaves, accelerating recovery.

Which characteristic of redwood trees offers typical protection against wildfire damage, but was overcome by the CZU Lightning Complex Fire?

A shallow root system that allows for quick nutrient absorption after fires.
A thin layer of bark that quickly dissipates heat.
A thick bark that acts as a natural armor. (correct)
An ability to store water in their trunks to combat dehydration.

What was the extent of the damage to Big Basin Redwood State Park caused by the CZU Lightning Complex Fire in August 2020?

The fire affected only the perimeter of the park, leaving the ancient redwoods untouched.
Approximately 50 percent of the park was affected, with significant damage to the understory vegetation.
Nearly all (97 percent) of the park was burned, including many of the ancient redwood trees. (correct)
Only a small section of the park was burned, with minimal impact on the redwood population.

How does the presence of bud tissue contribute to the resilience of redwood trees, as suggested by the research findings?

By enabling leaf regrowth from tissue that is almost as old as the tree, allowing for rapid recovery after damage. (B) Signup and view all the answers
