الملخص EN

A survey on aquatic macrophytes was done during 2006 to evaluate status of East Hammar marsh after restoration including two main stations Al-Mafrag (S1) and Al-Burgah (S2).

Ninteen plant species belonging to11 families of aquatic macrophytes were recorded in East Hammar marsh, one of them considered as an exotic species.The highest value of cover recorded for Ceratophyllum demersum as submerged 57.48% and Schoenoplectus litoralis as emerged 49.46%.

The most frequent species in the Hammar marsh was Ceratophyllum demersum (82.5%).The value of biodiversity was 1.96 and evenness was 0.74 while richness was 2.66 in S1.

Phragmites australis recorded the highest value of biomass in summer for emergent aquatic macrophytes, while Ceratophyllum demersum recorded highest values of biomass comparing with other submerged macrophytes
