Scientists find healthy Nubian giraffes in South Sudan
Researchers discovered that Nubian giraffes in South Sudan maintain genetic health despite severe population declines.
South Sudan hosts massive animal migrations where countless antelope travel between wetlands and grasslands annually. These savannas are home to Nubian giraffes, a specific subspecies of the northern giraffe found in East Africa.
Conflict and war caused major losses for local animals, leaving only 235 Nubian giraffes by 2025. This number dropped significantly from approximately 15,000 giraffes recorded in 1995 across the region's isolated pockets.
Small populations often face inbreeding risks when animals breed with relatives, potentially harming genetic health. Scientists collected skin samples from thirty giraffes in Boma and Badingilo national parks to analyze DNA.
Analysis compared South Sudan results with other populations like Kenya's Nubian giraffes to assess diversity levels. The study revealed relatively high genetic diversity and low inbreeding compared to similar groups elsewhere.
“The Boma–Badingilo savanna landscape is relatively untouched from human development and conflict.”
