A quick glimpse of the shore which lies opposite petrochemical plants on Pulau Bukom, the submerged reef of Terumbu Semakau and next to the Landfill.
July 2016, at the height of mass coral bleaching. At that time, We estimated about 70% of the hard corals and 40% of the leathery soft corals are bleaching. We estimate 5-10% of the corals have died then.
Jun 2017. No bleaching was seen and the soft corals were abundant again.
Boulder pore corals with dying upper patches that were grey and sloughed off. This is similar to what I saw at Sentosa Serapong last month.
Boulder pore corals had white upper parts. While the Branching pore corals were less affected.
Merulinid corals were bleaching, some with dying patches.
Brain corals seemed alright, with only some with large dead portions and bleaching.
Anchor coral colonies that were 99% dead with only tiny living portions on the bottom. Similar situation with Lettuce coral and Trumpet coral.
Carnation coral, Ridged plate coral and Disk corals. While Mei Lin pointed out a highly stressed Acropora coral that was bright pink. But I saw healthy clumps of Branching montipora coral. I saw two recently dead Cauliflower corals. I did not come across any Mushroom corals.
Anemone corals I saw were alright with only one small one that looked a little bleachy. I saw a few Galaxy corals that were also ok except for small dead upper portions.
leathery soft corals of all kinds. None were bleaching and most seemed alright.
I saw two Leathery sea fans with only living tissues at the tips. There were many Asparagus flowery soft corals, most of them alright, a few were oddly pastel. Zoanthids of all kinds and Broad feathery soft corals covered wide swathes of the shore. Some Broad zoanthids were rather pale.Magnificent anemones remain abundant on this shore, with many clumps even near the mid-water mark. The rest of the team saw anemonefishes in them.
Bubble tip anemones, Giant carpet anemones, Frilly anemones and I saw one Wiggly reef star anemone. None of them were bleaching.
Jun 2017 is still there. Although most of the netting seems to have disintegrated.
More about Pulau Semakau
Just as Changi Airport and Changi Beach are not the same even though they are near one another and share a name, Pulau Semakau is NOT the same as the Semakau Landfill. The Landfill was created by destroying all of Pulau Saking, and about half of the original Pulau Semakau by building a very long seawall. Fortunately, the landfill was constructed and is managed in such a way that the original mangroves, seagrass meadows and reefs on Pulau Semakau were allowed to remain.
Phase 2 of the Landfill was launched. This involved closing the gap of the seawall on the Semakau Landfill, forming one big pool where incinerated ash will be dumped. NEA worked to limit the damage to natural shoresduring the construction work for this expansion of the landfill.
The 2030 Landuse Plan by the Ministry of National Development released in Jan 2013 shows plans for 'possible future reclamation' (in light blue surrounded by dotted lines) that may impact the eastern shore of Pulau Semakau. More about the possible impact of the 2030 Landuse Plan on our shores.
