This activity explores an image of a wildebeest herd on the Serengeti, which serves as a phenomenon for learning about population dynamics and wildlife management.

In the 1960s, the wildebeest population in Serengeti National Park, Tanzania, began increasing at a rate much faster than before. Scientists determined that this increase was due to several factors, including the eradication of a disease called rinderpest. This image shows part of the Serengeti wildebeest herd, which is now the largest herbivore herd on Earth.
 
The “Educator Materials” document includes background information and implementation suggestions for using the image as a phenomenon. The “Student Handout” includes the image and background information.
