Overlogged and Thirsty: Bay Area Redwoods Are Struggling

This episode of Bay Curious explores the decline of redwood trees in the Bay Area, focusing on the environmental and human factors threatening these iconic giants. Once covering over a million acres, old-growth redwood forests have been reduced to less than 100,000 acres due to centuries of logging, especially during the gold rush and post-1906 San Francisco earthquake rebuilding. While redwoods are naturally resilient—adapting to fire, reproducing through sprouts, and surviving for over 2,000 years—they now face new threats from urbanization and climate change. Concrete infrastructure suffocates their shallow, wide-spreading root systems, while declining coastal fog and prolonged droughts weaken the trees, making them vulnerable to pests and extreme wildfires. Experts like UC Berkeley’s Todd Dawson and Save the Redwoods League’s Debra Zierten emphasize that while individual efforts like watering trees are helpful, systemic solutions—such as protecting forests through conservation organizations—are essential for long-term survival. The episode concludes with a call to action: preserving redwood ecosystems not just for today, but for future generations.
