Every year I see videos on National geographic of one of the most amazing and talked about migrations in the world. As I continue to see videos and learn about keystone species and the effects of their migration patterns I became more curious what started it and how it really works. Researchers say that they don’t entirely know what starts the migration aside from rains, just an innate ability to know. As the wildebeest and other plains animals begin to migrate it sets the eco system off. When they migrate it allows the grass to regrow and forces other animals to migrate as well. I would consider Wildebeests one of the key species in the African Serengeti and Masai.
