They did such a good job that, by 1926, no gray wolf packs were left in the park. Over the following decades, virtually every other part of the park's ecosystem was affected by the loss of the wolves --- from the animals who were their prey, to the plants that were the food for that prey, to the streams that were sheltered by those plants --- and the landscape was in distress. So, starting in 1995, in an attempt to reverse course, the government reintroduced gray wolves to the park. Over time, animal populations stabilized, waterways were restored and a healthy ecosystem was recreated across the land. It's a striking transformation, and a fascinating tale of life's complicated interdependencies.Jude Isabella's thoroughly researched, expert-reviewed text and Kim Smith's beautiful nature art bring science to life in this captivating story of renewal. Readers will recognize just how complex an ecosystem is and learn about the surprising interconnectedness of its members. Biodiversity, ecosystems, the food chain, habitats, needs of living things and the importance of human stewardship of the environment are all covered through this real-life example, offering direct links to earth and life science curriculums. Food web infographics help reinforce the information. A glossary and index add to the book's usefulness.

    But there was a time when people hunted the otters almost to extinction. Without sea otters to eat them, an army of hungry sea urchins grew and destroyed entire kelp forests. Fish and other animals that depended on the kelp were lost, too. But when people protected the sea otters with new laws, their numbers began to recover, and so did the kelp forests. Susannah Buhrman-Deever offers a beautifully written account of a trophic cascade, which happens when the removal of a single element affects an entire habitat. Asides that dig deeper are woven throughout Matthew Trueman’s dynamic illustrations, starring a raft of charismatic sea otters. Back matter includes more information about sea otters and kelp forests, including their importance and current status, the effects of the international fur trade on indigenous peoples, and a list of books and websites for readers who wish to continue to explore.
