The gray wolf depicted in the diorama used to be found throughout the United States—from New England to the Pacific Northwest. By the 1980s, there were only a few small pockets of survivors left in the continental United States. Over the past 20 years, the wolf has made a successful comeback in some of its former habitat due to strong conservation efforts. In April 2011, the gray wolf was removed from the endangered species list and it is now legal to hunt them. Many farmers worry that wolves endanger livestock and want the wolf population reduced. Invite your students to research this issue from both points of view and prepare their own arguments for a classroom debate.
