The Nature Conservancy reintroduces bison and fire to re-create the functioning ecosystem. Grazing by bison plays an instrumental role, nurturing around 750 species of plant life, birds and wildlife. And dont call them buffalo.
Technically, they are bison, said Steve McGuffin, director of philanthropy at The Nature Conservancy. Real buffalo have wide, curved horns and live in South Africa (Cape buffalo) or Asia (water buffalo).
