Decline of Forest Elephants in Central Africa

PLoS ONE

A recent survey of African forest elephants has revealed a startling reduction in that animal's population and geographic range over the past decade.  Human population density, as measured by SEDAC's Gridded Population of the World (GPW v3) data set, and nearness to human infrastructure, as indicated by SEDAC's Human Influence Index (HII v2), are two of the strongest predictors of that decline along with hunting intensity, poor governance and absence of law enforcement.
