Más información sobre el libro
Long considered by humans as a threat to livestock, wolves are hunted as pests. In particular, the gray wolf has been hunted almost to extinction in parts of North America. But these keystone predators help keep an ecosystem in balance. This book details reintroduction programs that have helped populations recover - yet they still occupy only 10 percent of their historic range. Teacher's guide available.
