Savanna vs Forest Elephant
Definition
African bush elephant (Loxodonta africana) and African forest elephant (Loxodonta cyclotis) are now recognised as separate species. They have distinct mitochondrial lineages, so DNA can distinguish their ivory even when physical appearance is similar.
- Species
- Loxodonta africana (savanna) and Loxodonta cyclotis (forest)
- Marker type
- Mitochondrial DNA lineage
- Recognised
- As separate species since 2021 IUCN reassessment
- Habitat split
- Savanna: open grassland; Forest: Congo Basin rainforest
Common questions
Why does the species distinction matter in an ivory seizure?+
The two species carry different conservation status and population trends, so correctly assigning a tusk to savanna or forest elephant affects sentencing, trade-route inference, and which range states get notified under CITES enforcement channels.
Can the species be told apart just by looking at the ivory?+
Not reliably. Tusk shape and Schreger-angle patterns overlap between the two species, which is why forensic labs fall back on mitochondrial DNA sequencing when visual or radiographic methods are inconclusive.
