Tropical and subtropical grasslands, savannas, and shrublands are found in relatively low-lying areas or in plateaus up to 1,000 m above sea level. They are characterized by a mixture of grasses, shrubs, and trees. The grasses can grow up to 2 m tall and are often dominated by species of Pennisetum, Hyparrhenia, and Themeda. The shrubs and trees can reach heights of up to 10 m and are often dominated by species of Acacia, Commiphora, and Terminalia.
Flooded grasslands and savannas are found in areas that are periodically inundated by water. These areas can be found in the floodplains of rivers or in depressions that collect water during the rainy season. The vegetation in these areas is adapted to the periodic flooding and can tolerate long periods of inundation. The dominant species in these areas are often grasses such as Echinochloa, Panicum, and Paspalum.
