Cheetah and Wildebeest in East Africa
Protecting the Cheetah’s range also benefits other migratory wildlife, including those not currently protected by international agreements such as Appendix I of the CMS. The Serengeti- Mara-Tsavo landscape, for example, is home
not only to a globally important population of Cheetahs, but also to vast numbers of migratory Wildebeest, Zebra, Eland and Thomson’s Gazelle. In 2011, the Tanzanian government ensured that the proposed commercial road n...
