This work investigates the critical necessity of preserving the Serengeti ecosystem against the encroaching threats of human expansion and habitat destruction. Bernhard Grzimek, a renowned zoologist and director of the Frankfurt Zoo, alongside his son Michael, document their extensive aerial surveys and field research to advocate for the establishment of protected wildlife corridors. Their argument centers on the biological imperative to maintain the migratory patterns of East African fauna, providing a foundational text for modern wildlife conservation efforts.

This text is regarded as a seminal document in the history of international wildlife conservation, noted for its direct influence on the creation of modern national park policies in Tanzania. The narrative provides a dense, historically significant account of the ecological state of the Serengeti during the mid-twentieth century.
