Will elephants soon disappear from West African savannahs?

Precipitous declines in Africa’s native fauna and flora are recognized, but few comprehensive records of these changes have been compiled. Here, we present population trends for African elephants in the 6,213,000 km2 Sudano-Sahelian range of West and Central Africa assessed through the analysis of aerial and ground surveys conducted over the past 4 decades.
These surveys are focused on the best protected areas in the region, and therefore represent the best case scenario for the northern savanna elephants.
