South Sudan launches epic effort to protect the world’s largest mammal migration
South Sudan’s great migration — now confirmed as the largest land mammal movement on Earth — sweeps up to six million animals across the floodplains each year, following rainfall in a vast circular loop. A new 10-year partnership between the South Sudanese government and the nonprofit African Parks is working to keep it that way, blending aerial surveys and GPS collars with generations of Indigenous knowledge. Seventeen ethnic groups share this landscape, and for centuries they’ve left informal corridors of “No Man’s Land” open so wildlife can pass freely between them. Tribal members now serve as observers, technicians, and field operators in the conservation effort itself. It’s a hopeful reminder that the most enduring protection often grows from the people who’ve always lived alongside what they’re protecting.
