A total of 104 species were detected. Bacillariophyta,cyanobacteria and chlorophyta dominated both pelagic and benthic microphytic communities, with dinophytaand euglenophyta also comprising a large part of the pelagic assemblages. Artificial ponds were built with lowdensity polyethylene (LDP) covered with stones and sand and were also constructed with other plasticmaterials, such as PVC or high-density polyethylene (HDP), with no natural cover. Regression tests were used to analyze the relationship between plant species diversity (Shannon index H’) and physic-chemical pond water parameters. The test showed that the species diversity from the ponds was significantly correlated with pond’s type. LDP ponds contained a significantly wider range of microphytes and macrophytes species, in summer than in winter, than HDP. These artificial irrigation ponds have led to the creation of new water habitats for plant diversity conservation within semi-arid areas.
