This study was conducted to assess the ecological performance of the aquatic macrophyte Ludwigia stolonifera ( Guill .  Perr. ) P.H., family Onagraceae in three water habitats under different pollution loads. This emergent hydrophyte can grow and tolerate a wide range of habitats with different pollution levels (ecological plasticity) and produces high biomass (458g.dry wt. /m²) in autumn at site C and (400 g. dry wt. /m²) at site A, this indicated the survival in autumn across the year, while the lowest biomass was produced in winter season at site A (180 g. dry wt. /m²). The plant can absorb and accumulate heavy metals in its tissues with high concentrations, especially in spring and so it could be taken as a good bioindicator for pollution and used in bioremoval of heavy metals from polluted water.
