Reindeer-herding Ewenki hunters have lived in the forests of China's Greater Khingan Range for over three hundred years. They have sustained their livelihoods by collecting plants and herbs, hunting animals and herding reindeer. This ethnography details changing Ewenki ways of life brought first by China's modernization and development policies and more recently by ecological policies that aim to preserve and restore the badly damaged ecologies of western China. Xie reflects on modernization and urbanization in China through this study of ecological migration policies and their effects on relocated Aoluguya Ewenki hunters.
