A devastating fire sparked fears that California’s redwoods would never recover, but these old timers had a trick up their trunks, and utilized deep stores of energy in their roots to sprout new growth weeks after they were charred.
The story begins after lightning sparked a fire in California’s Big Basin Redwoods State Park during the early years of the recent drought. Scientists were worried about the ancient trees, but also knew that they evolved to deal with fire over millions of years.
Nevermind their thick shaggy bark which acts like a fireman’s coat—the fire blazed right up to their crowns, torching every needle along the way, and frightening scientists into thinking they would never recover.
“It was shocking,” Drew Peltier, a tree ecophysiologist at Northern Arizona University, told Science Magazine. “It really seemed like most of the trees were going to die.”
Though thin, the pine needles of a redwood contain all the necessary equipment for photosynthesis, and when the fire burned them all, it was unclear how the tree would create energy for itself, but a new paper published by Peltier and his colleagues shows that new buds had been lying dormant for a long time under the bark of these trees, and sugars produced from photosynthesis decades ago were used to power these buds out into the sunlight.
