I was reading a story the other day related to primate enrichment at the National Zoo in South Africa. Their goal was to create an enrichment program for their baboons in an effort to increase activity and decrease aggression within the group. The group consisted of 1 male and 3 females. To deal with the aggression they gave contraceptives to the females which definitely helped with the aggression but they felt they could do more to enrich the lives of these baboons. This article will show you some very inexpensive ways to enrich the lives of primates kept in captivity.
