169CHA016 - Sebkhet Sidi Masoud

Description

Sebkhet Sidi Masoud is located at the south-east of Chargui island in Kerkennah Archipelago, just outside the village of El Ataya. The whole area was included in the national wetlands' inventory under the code 169 (Hughes et Al, 1997). It is a coastal saltmarsh with an elevation that ranges from 0 to 2.5m above sea level (Topography Map, 1973; Etienne, 2011) which get regularly flooded by the high tides. In the past, it used to be larger and water used to circulate freely up and down the area, but 2 years ago, a dike was built in the middle to stop sea water from reaching the houses located at the edge of the wetland and thus deviding it into 2 smaller systems. The eastern system (by the sea) is well preserved and has more than 95% of its surface covered by salicornia, whereas the other part (on the other side of the wall) is heavily degraded; the vegetation has been entirely removed and the land has been covered by soil making the ground higher. Building the dike stopped the natural flow of water which started to stagnate and therefore creating major problems for neighbouring residents (bad smells and mosquitos). Additionnaly, a lot of garbage, brought from the sea by tides and waves, are scattered along the shoreline. The dominant flora specie in the wetland is Sarcocornia fruticosa (L.) A. J. Scott.
