Bladderwort colonies : lemnoutricularietalia

The order Lemno-Utricularietalia consists of thermophile communities which are distributed mainly in Middle and Southern Europe. This vegetation type has one or two layers which consist of free-floating species on the surface and insecttrapping species underneath. The determining ecological factor is the organic material and detritus richness of the dystrophic water. Crustacean fauna of the habitat is usually rich in species. Stands frequently appear in shaded waters surrounded by reed vegetation (Borhidi 2003)
