Mollusken in een verlandingszone in het Markermeer

An inventory was made in July 2016 and September 2017 in a remote accretion zone in lake Markermeer along the dam separating the lake from lake IJsselmeer. Development of such a zone was possible due to the construction of small longitudinal dams at variable distances along the separation dam in the 1990s. Results of the inventories from both years are presented.
