DESCRIPTION: AMAZING GRAZING. By Chris Peterson.
The American West is famous for battles between cowboys, war between white settlers and Native Americans, and for the amazing wildlife that populated the plains. But the settlement of the West by white settlers nearly decimated the grasslands and the wildlife indigenous to the American West. Recent years have seen ranchers realizing the decline in the natural habitat of wildlife and taking steps to ensure that the damage caused in the 19th and early 20th centuries would halt before more wildlife and natural grasslands are destroyed. Amazing Grazing highlights the efforts taken by three ranches in Montana to protect the environment of the American West. The text is informative and catalogues the different ways that the three ranches protect the environment, while still maintaining a working ranch. Full-color photographs of each ranch are included, which show the natural grassland, the indigenous life in the area, and different aspects of the working ranches.
