Kew area. Freshwater meeting

Meet at Kew Gardens Railway Station (London Underground, District Line, Richmond branch and the North London Line) (map reference TQ 192767) at 12:00 h.   The low tide is late in the day (about 18:20 h) so we will look at two local Balea biplicata sites first and then make our way to the River Thames.   There is an exposure near Chiswick Bridge of a subfossil deposit (about 300 years old) on the foreshore near low tide mark that contains an interesting assemblage of freshwater molluscs.   Corbicula fluminea is now well established in the area and has a variable shell morphology.   Specimens should be easy to find.
