Factors affecting three species of the emergent Macrophytes assemblages along East Hammar Marsh

Abstract EN

The communities of emergent macrophytes and environmental factors were studied in four sites of East Hammar marsh (Harer, Al-Sadda, Al-monthory and Burka) during January to December of 2010.

This research aimed to identify possible present and past data of some environmental factors and human activities in the surrounding land-use.

Quantitative data were collected on emergent macrophytes density, vegetation cover, biomass and their relationships with environmental factors and human activities (cutting and grazing processes).

Three different perennial species Typha domingensis, Phragmites australis and Schoenoplectus litoralis were dominated in East Hammar is subject to many anthropogenic activities and impact of human toward emerged plants vegetation cover and biomass was more than changing in water quality of the marsh
