I am studying the diverse relationships between humans and wildlife in the forested areas of southeast Guinea in West Africa. Focusing on the latent potential for conservation of forest and wildlife represented by the landscape that has traditionally been maintained by swidden villages, I have conducted research on the conservation ecology of local wildlife, analyzed the organization and origins of traditionally-maintained forest reserves, and studied the indigenous inhabitants’ struggle to identify future conservation strategies.
