Map of Balgzand, showing location of the 15 sampling sites: 12 transects of 1 km each (marked 1–12) and 3 squares of 900 m² each (A–C). Thin lines are the borders of the intertidal area. Mussel beds were present along parts of transect-4 (in all years 1970 till summer 1990), transect-5 (in all years 1970–2005, except 1990/1991), transect-8 (infrequent and short periods), and transects-9 and -10 (frequent short periods)
