Divers with SCUBA pulled out plants with their root systems and adhering mud until 9000 cm3 of material had been collected. Again 10 samples were collected, but these are not comparable with the samples taken in January or from the other zones. We found collecting in the Posidonia difficult and this zone was not well sampled. In addition to the volumetric samples, the population density and size distribution of the Sydney cockle Anadara trapezia was measured using a quadrat in the lower Zostera. A quadrat was used also to estimate the biomass of Zostera and Posidonia. The quadrat was placed randomly ten times in each zone and all plant material was removed from within the quadrat. The plants were washed, excess moisture and epiphytes removed and the plants weighed. The samples were then dried at a constant humidity and temperature (21°C) ad re-weighed until constant ?-\ 8S2* Zostera \ Sandy iP Mang if in Salt A.
