Molluskeninventarisatie van het Ruigeplaatbos en de Visserijgriend in Hoogvliet, Rotterdam: bijzondere vondsten en een hoge diversiteit

In the last months of 2018 an investigation was carried out of two freshwater tidal areas along the north bank of the Oude Maas: Ruigeplaatbos and Visserijgriend (Hoogvliet, Zuid-Holland, the Netherlands). During the fieldwork not only the species ‘Murchisonella spec.’ was found, as reported in an earlier paper, but also numerous other remarkable finds (e.g. Assiminea grayana, Myosotella denticulata, and high numbers of Mercuria anatina). This shows that these two areas contain an interesting fauna and high diversity, most likely caused by a diversity in habitats.
