Rock and Rubble Reefs
The Tewantin reach has several large areas of gravel with dead oyster shell (Figure 3.9) and
rocky rubble (Figure 3.10) that have been buried in places by up to 0.5 m of fine sediment
(Figure 3.11), particularly in areas of accretion adjacent to seagrass beds and upstream of
the rocky reef surrounding an existing channel marker (Figure 3.3). In intertidal habitat,
oysters aggregated in a narrow band in moderate to low densities on the rock rubble
adjacent to the existing mangroves along the bank edge (Figure 3.10). The densest
aggregation of oysters were limited to intertidal areas on existing pylons and the rock around
jetties.
