The Bristlecone Book: A Natural History of the World's Oldest Trees

"A very few Great Basin bristlecones have green seed cones that appear to be turning purple, and yellow pollen cones with reddish tips. And one 2,500 to 3,000 year-old Great Basin bristlecone in the Schulman Grove has been found to produce white pollen from its red pollen cones."

"A common suggestion is that the presence of living bark strips enables old bristlecones to persist by maintaining a balance of water-procuring roots and water-consuming foliage. In other words, sectored architecture slows death by allowing a tree to linger until the last vestige finally gives up the ghost."

"And what of those favored few trees that escape their adversaries and persist for millennia? What finally becomes of them? Can they live forever, and if not, what finally kills them?"
