For those who don't know a lot about trees, this can be an excellent introduction. There's sufficient scientific information to convey the wonder of trees without overwhelming one. ( ) This was a little different than I expected. I thought it was going to be more about the natural "movement" of trees and how that was accomplished, how frequently, the causes, etc., sort of a natural history. There was some of that, but it seemed to be more about the author's experience on how and why to move trees now. Some interesting factoids about trees, and what happens in a changing climate. Tree species grow best where they grow best, and not where they don't. This simple fact results in stands of trees of certain species in certain places that remain in stasis. For example the seed that falls from a tree into a place it doesn't do well will not grow there, thus the stand tends to stay in place unmoving and eternal. But if the climate changes this upsets the balance and trees begin to move, sometime rapidly. Birds can carry seeds thousands of miles in a single season. The old stands may die off and are replaced with new, while the original species may move somewhere else more favorable. Some species like Sequoia used to cover much of the north hemisphere and are today relegated to small pocket valleys on the west coast, hanging on to those few remaining places where they do best. A fascinating perspective on how mobile forests are, when you take the long view. sem críticas | adicionar uma crítica

Forests are restless. Any time a tree dies or a new one sprouts, the forest that includes it has shifted. When new trees sprout in the same direction, the whole forest begins to migrate, sometimes at astonishing rates. Today, however, an array of obstacles-humans felling trees by the billions, invasive pests transported through global trade-threaten to overwhelm these vital movements. Worst of all, the climate is changing faster than ever before, and forests are struggling to keep up. A deft blend of science reporting and travel writing, The Journeys of Trees explores the evolving movements of forests by focusing on five trees: giant sequoia, ash, black spruce, Florida torreya, and Monterey pine. Journalist Zach St. George visits these trees in forests across continents, finding sequoias losing their needles in California, fossil records showing the paths of ancient forests in Alaska, domesticated pines in New Zealand, and tender new sprouts of blight-resistant American chestnuts in New Hampshire. Everywhere he goes, St. George meets lively people on conservation's front lines, from an ecologist studying droughts to an evolutionary evangelist with plans to save a dying species. He treks through the woods with activists, biologists, and foresters, each with their own role to play in the fight for the uncertain future of our environment.
