The Nile Delta flooded savanna, ecoregion covers both the Nile Delta proper, where the Nile River enters the Mediterranean Sea, as well as the river floodplains of the Nile 1,100 kilometres (680 mi) up-river to the Aswan Dam. Since the Aswan Dam was completed in the 1970s, the Nile on this stretch has not been subject to annual flooding, leading the loss of much of the papyrus sedge swamps and other marshes along the river.

The North Saharan steppe and woodlands is a desert ecoregion, in the deserts and xeric shrublands biome, that forms the northern edge of the Sahara. It extends east and west across Northern Africa, south of the Mediterranean dry woodlands and steppe ecoregion of the Maghreb and Cyrenaica, which is part of the Mediterranean forests, woodlands, and scrub biome. Winter rains sustain shrublands and dry woodlands that form an ecotone between the Mediterranean climate regions to the north and the hyper-arid Sahara Desert ecoregion to the south.
