From information to environmental action, this stunning book presents an informed and comprehensive explanation of how the balance of nature has been restored to Yellowstone, as naturalists have worked to return the wolf population to the park. The importance of predators as keystone species is emphasized in this NSTA/CBC Outstanding Science Trade Book for 2009.
Breathtaking photographs are juxtapositioned within a beautifully written, dual-text format, to inform and engage the reader. Notes about the photographs, an index, and more references for further investigation all make this a great source to apply or extend lessons on habitats and ecology from middle school through adult.
