Grade 2–5—Removal of one predator—the wolf—from Yellowstone National Park caused the decline of many animal species, subsequently changing the very terrain of the area as ponds and trees also disappeared. The rise and fall and interdependence of species are explained simply in this slim survey of some of the park's wildlife. Patent begins with the Congressional designation of Yellowstone as a national park in 1872, stating that in the early years the geologic wonders rather than the animals were the main attraction. The wolf was a popular hunting target, and its demise led to an overpopulation of elk and coyotes and a complex chain of effects. The format sets small chunks of text and two or three small color photographs on a black background at the far right of the spread. A large color photo fills the remaining space, with a framed sentence superimposed on the picture. The two blocks of text become repetitive, but they're apparently intended as a dual-level text, so that children can read either the briefer explanations on the left or the longer ones opposite. Bits of background terrain are seen in the pictures, but they do not capture the dramatic decline and renewal of the ecosystem suggested. There is no map to indicate the large size and location of Yellowstone. The book concludes with a review quiz with small animal photos.—Margaret Bush, Simmons College, Boston
