The Guarijo Indians live in the southern portion of the state of Sonora, Mexico in the Sierra Madre Mountains. The tribe has lived in these mountains for centuries, but until the 1970s where held in virtual slavery by wealthy landowners. This program is about the Guarijo and their land. Through an uprising they regained control of the land they call home, located in a tropical deciduous forest rich in plants and animals. The Guarijo are intimately tied to the land. The program features ethnobotanist David Yetman from the University of Arizona's Southwest Center.
