Where necessary for monitoring purposes the Ol Pejeta Conservancy collars individuals of certain species including lion, cheetah and elephants. This allows for the development of home range maps and greater understanding of the habits and movements of these species.

With prior arrangement, lion tracking trips with members of the Ol Pejeta research staff can be arranged.

Radio collars assist the Ecological Monitoring Department to obtain data on predator-prey interactions, population status and structure, movement patterns and social organisation. Through the use of collars, prey mortality caused by predators can be analysed to show their impacts on prey species. Too many lions, for example, can be a problem because high prey off-takes can lead to a serious decline of endangered and other species of concern to the Ol Pejeta Conservancy, including Jackson’s hartebeest, Grevy’s zebra, black rhinos, Beisa oryx and ostriches. With the help of the collars and patrol reports, monitoring had established that the hartebeest population in the eastern sector of the Conservancy, for example, had fallen by approximately 50% in the last 10 years. Predators alone accounted for 82% of their deaths. Without collars the same data can be collected but collars allow closer monitoring on a more regular basis.
