‘For centuries, the whitebark pine, Pinus albicaulis, has grown on hundreds of thousands of acres across the West. It is a keystone species of an entire ecosystem — one now seriously at risk. Most of the whitebark pines in Yellowstone and Glacier National Parks are dead. It has been declared an endangered species in Canada. And, last week, the Fish and Wildlife Service stated that the whitebark pine “warranted” listing as threatened or endangered, making it one of the very few species officially acknowledged as threatened by climate change.’
