The Nile Delta Flooded Savanna ecoregion extends along the River Nile from the Aswan High Dam, 1,100 km downstream to the mouth of the Nile as it enters the Mediterranean Sea. The delta is about 175 km long and 260 km wide (Hughes and Hughes 1992). Since the construction of the Aswan High Dam, the riverine floodplains and delta are no longer subject to annual flooding, and Cyperus papyrus swamps that used to exist in the wettest areas have largely disappeared. The remaining marshland is associated with lakes and lagoons along the seaward face of the delta. Outer margins of the delta are eroding, and salinity levels of some of the coastal lagoons are rising as their connection to the sea increases.
