Survey teams use traditional knowledge together with scientific approaches to identify and calculate density of fecal matter by animal species. Mr. Cysco Charlie is Basarwa tracker skilled in identifying the movements and tracks of wildlife. Dr. Alexander and Mr. Charlie have been working together for nearly a decade in Botswana studying human, environmental, and animal interactions.

Here, Cysco works with Dr. Alexander and the rest of the field team determining fecal density, age and even sex by animal species along the Chobe River. Study transects have been established along the river as it moves from the towns of Kasane and Kazungula into the world famous Chobe National Park.These points are the focus of longitudinal environmental monitoring.
