A beautifully written account of the symbiotic relationship between pine trees and jays; a cycle of dependency has progressed for several million years as birds have effectively planted the trees that sustain them by dispersing the seeds. This book covers a wide range of regions, focusing on the Rocky Mountains and the American Southwest, but also ranging from the Alps to Finland, and from Siberia to China. The book is written from the perspectives of evolution, ecology, and animal behaviour.

High among the cold, windswept peaks of America's mountain West, strange and beautiful trees grow old but never age. The Bristlecone book: A Natural History of the World's Oldest Trees brings together for the first time the captivating facts about bristlecone and foxtail pines-trees that thrive in a harsh environment and live thousands of years-with a special focus on Great Basin Bristlecone pine, the oldest tree species on earth. In this extraordinary journey into the world of bristlecones, author Ronald Lanner exposes the trees' inner workings, taking apart a pine to examine bark, buds, needles, cones, and roots, and wood. He follows a tree's lifespan from seedling to great old age, presenting a new interpretation of stages of growth. He explains the unusual colors and forms that make bristlecones so picturesque, describes how the forces of nature influence the trees' unique shapes, and reveals their secrets of long life. Readers will discover where to go to see these trees and how to identify them. A stunning pageant of color photos shows off bristlecones and their remarkable growth patterns, and a map shows locations of groves.
