Sequoias and the Drought

Guest: Anthony Ambrose, PhD, Tree Biologist at UC Berkeley  The largest known living tree on the planet is named “General Sherman.” It’s a Giant Sequoia in California, tall as a 25-story skyscraper and 100 feet wide at the base. Picture a trunk larger than a pro-basketball court. General Sherman is estimated to be more than 2000 years old.  If you’ve visited Sequoia National Park, you felt how immense and permanent these trees seem. But might they have met their match in the record-breaking drought that grips California?
