As well as a rich and wide range of wildlife, Selous Game Reserve also boasts a great diversity of vegetation, including rocky acacia-clad hills, gallery and ground water forests, swamps, and lowland rain forest. The most noticeable landscape being the Miombo woodlands which dominates most of the area with over 2,100 plant varietals. Large parts of the wooded grasslands of the northern Selous are seasonally flooded by the rising water of the Rufiji River, creating a very dynamic ecosystem.
