| Abstrakt: | Floristic surveys and phytoecological relevés were conducted on 36 temporary wetlands of Mogods region. Multivariate analyses (CA, AHC) performed on these data reveal the high specific and biocoenotic diversity of Mogods wetlands, which appear controlled by substrate nature and hydrology. Among the 128 hydrophytic species inventoried, 38 are presently in precarious status and 6 are presumed extinct. The Mogods region harbours, moreover, very rare habitats (peatlands and semi-permanent lakes), and a vast plain so-called Garâa Sejenane, exceptionally rich in temporary wetlands. These results underline the urgency of an adapted conservatory management, based on the development of scientific studies dealing with structure and functioning of hydrophytic communities of the region.
