Natural History A Natural History of the Intermountain West was written to inform people about the wild world around us, with the idea that we all crave a connection to the natural world to ground us and give us a sense of place. It is also a book about change. While species are described throughout the chapters, the text is focused more on the profound processes that have shaped western ecosystems, based on a belief that understanding those processes is more meaningful than a list of names. The ways and the rapidity with which enormous ecosystems replace one another and sometimes even return as climates change are a magnificent testament to the tenacity of life. The first book of its kind for this region, Evolution and Ecology takes a fresh look at the natural history of the southern Rockies and the Intermountain Region based on cutting-edge research, interviews with numerous scientists, and the author's personal experience. Drawing together many disparate fields, the book integrates the evolution of western ecosystems with the geological and climatic history of the region. It is a passionate, humanistic, and scientific treatment of this area's ecosystems, how they function, and how they came to be through time; it is a wonderful guide for the general public and scientists alike.
