Résumé :	The Roque-Haute Natural Reserve (Herault, France) encompasses an exceptional natural heritage comprising more than 200 oligotrophic Mediterranean ponds. In those natural habitats grows an inestimable flora including 24 protected species of plants. In Roque-Haute, very rare plant associations were first described by phytosociologists, of which numerous amphibious communities have been placed under the "Habitats Directive" of the European Union. Often, these associations are gathered in the same pond, which then has to be considered as the effective unit for management. A pond typology based on the vegetation physionomy and dominant plant species has been suggested for use by the site manager. At the present time, most of the problems concerning rare plants and communities are correlated with invasive plants (and consecutive eutrophisation of water), such as helophytes (reeds, bulrushes, sea club-rushes), or sclerophyllous shrubs from the maquis (Cistus spp.), or deciduous trees growing at the pond edge (elms, ashes).
