Four new titles join Animals Back from the Brink, an informative and up-to-date series that explains how different animals around the world, once on the brink of extinction, are now surviving and improving. Accessible text examines the reasons the animals were threatened, the impact of humans on natural environments, and the strategies - both successful and unsuccessful - that were put in place to help the species recover. Each book highlights the collaborative efforts of different organizations involved in the long-term monitoring of the animals and discusses whether the same solutions can be applied to other species. Dynamic images combine with useful maps, details on recovery plans, and profiles of the people involved. A link printed inside each book gives readers access to Crabtree Plus, a website featuring supplemental digital content, including interactive activities that reinforce and extend key series' concepts. Free downloadable Teacher's Guide available.
