It’s not easy to survive century after century, through droughts and storms and oscillations of the climate. So California’s majestic coastal redwoods have developed a few tricks, like their great height: The trees can grow to more than 350 feet high, allowing their treetops to pull in moisture from the fog to keep their water levels refreshed. But, according to a new study in the Proceedings of the National Academy of Sciences, the fog is on the decline, which could spell trouble for redwoods and other area species.
Fog often rolls ashore along the California coast from June through September. The hot, dry inland air rises and creates a vacuum that sucks in the cold, vaporous air from over the ocean [Wired.com]. While the small strip of land about 50 miles inland from the coast where the redwoods live is dry and hot, this influx of moisture keeps the giant trees hydrated.
