Overview
- The new Nature Communications study analyzed 232 whole genomes from savanna and forest elephants across 17 countries and found broad genetic health with pockets of concern.
- Researchers flagged isolated groups on the range edges for inbreeding and harmful mutations, including about 100 elephants in Eritrea and roughly 300 at Ethiopia’s Babile Elephant Sanctuary.
- Elephants in southern Africa retain strong diversity because they can still move between protected areas, highlighting the need to secure cross-border links and habitat corridors.
- A small amount of forest–savanna hybridization in parts of West Africa helped some isolated savanna herds keep diversity, yet scientists advise against mixing the two species or distant regional lineages during translocations.
- The team says the genomic maps can guide corridor planning, cautious relocations, and ivory source tracing, and notes many samples predate recent poaching spikes that could worsen risks.
