Kenya's Black Rhinos.

In the past 30 years, poaching has reduced Kenya's black rhinoceros population from 20,000 to a mere 400 as of January 2004. Only a close examination of interactions between these competing large mammals and the sanctuary's carrying capacity will maintain a healthy ecosystem and preserve the last black rhinos. One can help Linus Gatimu, Geoffrey Wahungu and Alan Birkett study the ecology and behavior of the black rhino in an enclosed savannah ecosystem. Besides patrolling for rhinos, you'll measure acacia trees to determine vegetation growth.
