Full description

This research was conducted to understand the relationship between water quality and ecological attributes on coral reef communities, through field surveys on naturally turbid inshore coral reefs that vary in exposure to water bourne sediment, nutrient and chlorophyll concentrations. Reefs in two regions were surveyed for biodiversity of algae, hard corals, octocorals and fish. Region PC: Princess Charlotte Bay (in the Claremont Isles, north of PC Bay) and and Region WT: Wet Tropics (between Tully and Port Douglas). SOme reefs were surveyed for the all four groups of taxa, while others were surveyed for some groups of the biodiversity. Four groups of taxa were surveyed using rapid ecological assessments based on standardized scuba-swims by experts: 1 -macroalgae, mostly identified to genus level 2- hard corals , idenified to species level 3- octocorals, identified to genus level 4 -fish, identified to species or species groups Abundances of the three benthic groups were rated on a 6-point scale as 0 = ‘absent’, 1 = ‘rare’, 2 = ‘uncommon’, 3 = ‘common’, 4 = ‘abundant’, and 5 = ‘dominant’.
