Cyperus papyrus
Near the river mouth in Tanzania, the rapidly fluctuating water levels in Lake Victoria of the previous century have further added to discharge difficulties of the Mara River. Consequently, floods have become more common and large parts of the Tanzanian Mara wetlands have become more permanent instead of temporary wetlands. These dynamics have caused a subsequent land cover change from dryland (that occasionally flooded) to wetland forests, to wetland vegetation with varied water-related plants as mentioned above, where eventually the "Cyperus papyrus" has become one of the most dominant species.
