East Africa’s 25,000 sq km Mara-Serengeti ecosystem is often called The Last Place on Earth. It is defined by the nomadic wandering of 1.2 million wildebeest, 200,000 zebras and 400,000 gazelles, a moveable feast for the lions, leopards, cheetahs, hyenas and wild dogs that prey on them. It is a Pleistocene vision, a reminder of a time when human beings were an integral part of the landscape, moving according to the seasons in search of food and shelter.
Today, the “great migration”, as it is known, is under mounting pressure from the burgeoning human population. Competition for grazing, large-scale wheat farms, the impact of the bushmeat trade, rampant tourism development, global warming, invasive plant species, and deforestation in the Mau Forest in Kenya (where the dwindling Mara River rises) are all causes for concern. In this beautifully illustrated talk, Jonathan and Angela Scott also highlight the demise of the four other most threatened wildebeest migrations in East Africa – the Athi-Kaputiei, Amboseli, Mara-Loita, and Tarangire-Manyara migrations, and touch on the current status of elephant, vulture and flamingo migrations in the region.
