Structures de végétation et conservation des zones humides temporaires méditerranéennes : la région des Mogods (Tunisie septentrionale)

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