Good write up indeed. I learnt more about our fragile marine environment today!


Nice write-up. I recall at this point in time that corals do actually wage warfare against one another, stinging each other until they withdraw into their own little spaces; I wonder if the relocation plans have taken this into account.


Attenborough's Blue Planet series has an episode showing this gory coralistic competition. But somehow I doubt the folks behind this project have as good a grasp of the island's marine ecology and true biodiversity as the people behind the Hantu Blog and the Blue Water Volunteers. The SUF seems to have the notion that a shallow lagoon can be turned into a flourishing crystal clear reef just by throwing in corals from other reefs and adding a filter ala a reef aquarium.


I do not know anything about marine ecology.

However I fear that the results by the Singapore Environment Council to "preserve" the reef ecology will be not every different from what resulted in URA's attempt to "preserve" cultural heritage by the redevelopment of the Bugis/Chinatown area.


Coral competition is not very weel know, and may not always be chemical in nature. Another strategy is to just overwhelm the competition by overgrowing them. Acropoa (Staghorn)corals can do this quite fast, which is why some reefs are dominated by such corals. However, these Acropora corals are (usually) impacted by sediment and low light conditions.

Certainly, coral reef biology is a complex ... there are hundreds, if not thousands, of interactions that are unknown.

Cheers, Jeff
