Add to basketThe mollusk fauna of the Rhine floodplain near Hördt (Rhineland-Palatinate) a critical comparison after more than four decades Between 2008 and 2011 a survey of the mollusk fauna of the Rhine floodplain near Hordt focussing on the species listed in the annexes II and IV of the European Habitats Directive was conducted. Results w…ere compared with investigations on the land snails and freshwater molluscs in the 1960th and 1970th. With about 1,500 single records and nearly 25,000 specimens collected from more than 60 sites the new survey yielded, among others, the first local records of the rare and endangered species Anisus vorticulus, Vertigo moulinsiana, Gyraulus riparius, and Pisidium pseudosphaerium and added significantly to the known list of species. Simple comparative analyses showed that especially the older aquatic assessments despite their own claim did not prove adequate to reveal faunal changes. Methodological deficiencies alone feasibly accounted for the differences observed. For this reason, with exception of Unio crassus, population trends could not be determined in the annex-species of the Habitats Directive either. Comprising a total of 133 species including four presumably locally extinct taxa, the area near Hordt probably is the floodplain with the highest diversity and concentration of endangered mollusk species in the entire Upper Rhine Valley. In total, 40 % of the species are either on the Red list of Germany or Rhineland-Palatinate, four of eight species in the category "critically endangered" still survive in the area, another twelve species are ranked as "endangered". The importance of the area as an inactive floodplain of excellent conservation status with its typical advanced succession stages is emphasized. The relative isolation of the area from the Rhine main stream guarantees the survival of many species by protecting them against the unnatural floodplain dynamics and fluctuating water quality. Anisus vorticulus is presented as indicator species for such conditions. 42 pp., 13 figs, 6 tabs, gr. 8.
