There is no saying which trees will die, but by [Biologist Greg Asner's] estimation the count statewide could be close to 120 million — as much as 20% of the state's forests...Park Williams, a bioclimatologist at the Lamont-Doherty Earth Observatory at Columbia University who has been studying the California drought, is not surprised by Asner's numbers.
