Notes from Understory: A Berkeley Biologist Gauges the Health of the Redwoods from the Ferns on the Forest Floor.

Emily Burns was driving north from the Bay Area one day, idly woolgathering, when it hit her.

“Western sword ferns,” she recalls thinking. “They’re twice as big in the northern end of their range as in the southern end. And it struck me that it had to be due to water availability. The fact that it’s wetter in Redwood National Park in Humboldt County than, say, Lime Kiln Creek on the Big Sur coast translates as larger ferns in the north. It all seems obvious now, but there was nothing in the literature on it.”

Saving the Sequoias: The Most Magisterial of Trees in California Face a Big Risk

Ronald Reagan was (in)famously unmoved by ancient forests, claiming that “when you’ve seen one redwood, you’ve seen them all.” But most of us still feel a frisson when we stroll among old-growth trees, particularly when they’re the biggest dang trees on the planet: Sequoiadendron giganteum, otherwise known as giant sequoias. (That’s biggest by volume, by the way. Coast redwoods, Sequoia sempervirens, may be taller but typically are more slender.)
