Elephant Trails 1 (IMAGE) Purdue University Caption Elephants act as engineers of the forests. These massive creatures trample thick vegetation through dense forests in the Central African Republic's Congo Basin as they move from the forests' fruit trees to more open water sources where they hydrate, bathe and socialize. Remis and Jost Robinson focus on these massive trail networks as well as the ecosystem and local foraging community, called the BaAka, as they evaluate how biological anthropology plays a role in conservation.
