2. Wildebeest Population Data

1

Describe how the historical data compares to the data you collected during the simulation.

Before 1960, a disease called rinderpest was killing many of the animals in the Serengeti. The disease spread from domestic cattle to wild animals like wildebeest and buffalo. In the early 1960s, the cattle began being vaccinated against rinderpest. By 2011, rinderpest was considered to be completely eliminated.
