Tsetse fly
The Selous Game Reserve in southeastern Tanzania is a hunting reserve named in his honor. Established in 1922, it covers an area of 54,600 km2 along the rivers Kilombero, Ruaha, and Rufiji. The area first became a hunting reserve in 1905, although it is rarely visited by humans due to the significant presence of the Tsetse fly. In 1982 it was designated a UNESCO World Heritage Site due to the diversity of its wildlife and undisturbed nature.
