Both species of rhinoceros in Africa are endangered, in large part due to the value of rhino horn on the black market. In the western part of South Africa’s Greater Kruger National Park, a group is working to keep these animals safe in spite of the bounties on their horns. The Black Mambas are a woman-only group of rangers that patrol the wildlife reserve to protect against poaching. 

Tsakane Nxumalo, a ranger with the Black Mambas, joins host Jay Ruderman to talk about their rigorous training process, the role of education in conservation work, and what role her gender plays in her work.
