Idea for Use in the Classroom

To begin, have students read this case study on Arthur Middleton and his work to protect elk migration in the Greater Yellowstone ecosystem.

After reading, divide the class into nine groups, or “herds,” as named on Elk Migrations of the Great Yellowstone Ecosystem map, found on page four of the case study. Ask each group to use the map to write down a description of its herd to share with the class. Instruct each group to include what the herd does throughout the year, whether or not they migrate, why they do or do not migrate, and where in the park they live. The descriptions can be written on the board, on poster board, or shared digitally if students have access to computers. When everyone is finished, have each herd present their description to the rest of the class.

After the presentations, have a class discussion. Ask students: Which herd do you think has the easiest life? Why? Why do herds migrate? Have students specify information from the infographic that supports their answers. Encourage students to consider migration routes, access to food, predation, hunting, and features of elk habitats.
