The book uniquely presents giant sequoias' life history through their tree ring records, revealing long-term ecological stories. It investigates their anatomical and physiological traits, such as their thick bark and decay-resistant wood, which contribute to their resilience.
The book progresses by introducing the foundational principles of dendrochronology and then analyzing tree ring records to disentangle the influences of climate variability and fire frequency on tree growth. This approach integrates earth sciences, geography, and nature, providing a holistic perspective on sequoia longevity and the challenges of conserving these iconic species.
