A troubling story of the devastating and compounding effects of climate change in the Western and Rocky Mountain states, told through in–depth reportage and conversations with ecologists, professional forest managers, park service scientists, burn boss, activists, and more. Climate change manifests in many ways across North America, but few as dramatic as the attacks on our western pine forests. In Trees in Trouble, Daniel Mathews tells the urgent story of this loss, accompanying burn crews and forest ecologists as they study the myriad risk factors and refine techniques for saving this important, limited resource. Mathews transports the reader from the exquisitely aromatic haze of ponderosa and Jeffrey pine groves to the fantastic gnarls and whorls of five–thousand–year–old bristlecone pines, from genetic test nurseries where white pine seedlings are deliberately infected with their mortal enemy to the hottest megafire sites and neighborhoods leveled by fire tornadoes or ember blizzards. Scrupulously researched, Trees in Trouble not only explores the devastating ripple effects of climate change, but also introduces us to the people devoting their lives to saving our forests. Mathews also offers hope: a new approach to managing western pine forests is underway. Trees in Trouble explores how we might succeed in sustaining our forests through the challenging transition to a new environment.
