Serengeti: East Africa's Great Savanna and the Annual Migration

Landscape and protected areas

The Serengeti mosaic includes open plains, riverine forests, kopjes (rocky outcrops) and seasonal floodplains that respond to distinct wet and dry seasons. These habitat types support complex food webs and fuel seasonal movements of animals. Within the region are several formal conservation units, such as Serengeti National Park, the Ngorongoro Conservation Area and Maswa Game Reserve in Tanzania, together with the Maasai Mara National Reserve in Kenya, which connects directly to the northern Serengeti (Maasai Mara).

Wildlife and ecology

The Serengeti hosts immense populations of grazing mammals and their predators. Estimates often note well over 1.6 million herbivores across the ecosystem. Characteristic species include the blue wildebeest (wildebeest), Thomson's and Grant's gazelles, and plains zebras, together with large numbers of African buffalo. Predators such as lions, spotted hyenas, cheetahs and Nile crocodiles depend on this abundance and shape patterns of survival and movement.

The Great Migration

The Serengeti is best known for the annual mass movement of grazing ungulates often called the Great Migration. Driven by seasonal rains and the search for fresh pasture, roughly one to one-and-a-half million herbivores—chiefly wildebeest, gazelles and zebra—move in a broad circle between the southern plains and the northern grasslands. Key events in this cycle include dramatic river crossings, notably the Mara River, where many animals face significant predation and natural obstacles (Great Migration).

Human history and archaeology

Beyond its living wildlife, the Serengeti region has deep palaeoanthropological significance. The Olduvai Gorge, located near the central Serengeti region, has yielded important fossil and archaeological evidence related to early human ancestors and stone-tool cultures. Find sites at Olduvai have contributed to understanding of early hominid evolution and prehistoric lifeways (Olduvai Gorge).

Conservation, tourism and challenges

The Serengeti's protected areas attract substantial tourism, which supports local economies and funds conservation, but the ecosystem also faces pressures. Land-use change at its margins, illegal hunting, competition with pastoral livelihoods, and climate variability pose ongoing management challenges. Collaborative approaches with Maasai and other local communities, park management, scientific monitoring and regulated tourism aim to maintain the ecological processes—especially the Migration—that define the Serengeti's global importance.
