What is it about?
Decades of survey data have been collected on elephant populations across Africa. However, until now they have not been analyzed together within a unified statistical framework. In doing so, we have been able to paint a more complete picture of changes in elephant population densities at different sites across the continent.

Why is it important?
As well as estimating an overall negative trend in both African elephant species, we were able to show that declines are not the same everywhere, with some regions, particularly in Southern Africa, registering an increase. This not only motivates further conservation action, but can be used to direct limited resources to regions where they are most needed, or to learn from the regions where conservation measures appear to be most successful.
