Pinus radiata: Monterey Pine

"The closed-cone Monterey Pine spread northward into California about 15 million years ago. By this time, Pinus radiata had already evolved into a distinct species that flourished throughout the Pleistocene. Not until a warm, dry period 4,000 to 8,000 years ago was driven to near extinction, surviving in the form of five small populations"
