mass coral bleaching here in 2016.
Today, I saw that many of the large coral colonies were not bleaching or only had small pale patches.
2 weeks ago.
mass coral bleaching here in 2016. When there were bright white corals on both Terumbu Semakau and Pulau Semakau.
There are not as many leathery soft corals here as on some other submerged reefs. Those I saw were mostly alright. A nice pink/brown colour that blended well with the surroundings.
Asparagus flowery soft corals, most were pale. I saw a few bleaching zoanthids. But saw two leathery sea fans that were alright.
Magnificent anemones on this part of the flat. None of them were bleaching (in fact, I've never seen a bleaching Magnificent anemone). Although some Magnificent anemones had pale body columns, they are like that all the time. There were also many Giant carpet anemones, I only saw one that was rather pale. Most Frilly anemones I saw were alright, only one that was pale.
Merten's carpet anemone and it was alright.
The Burrowing giant clam is still there! Giant clams can also suffer from bleaching, so it was good to see that this one seemed alright.
Banded file snake. Jonathan has created a lovely compilation of photos and videos of this very cute creature.
The seagrass situation seems similar to what I saw in May 2019, i.e., slowly improving. Although heavily covered with epiphytes, there was good cover of Spoon seagrasses on many of the pools in the middle of the reef flat.
Tape seagrass with longish leaf blades. Although also many clumps with short cropped leaves. I saw many small clusters of Serrated ribbon seagrass that looked fresh and green.
June 2010. Let's hope the seagrasses will return soon!
survey of Pulau Semakau 2 weeks ago. The trap was well weighed down by rocks. But there was nothing inside it.
Fate of Terumbu Semakau?
Terumbu Semakau is one of the existing natural shores that may be impacted by the landuse plan by the Ministry of National Development released in Jan 2013 in response to the Populations White Paper with a 6.9 million population target. The dotted margined blue areas are "Possible Future Reclamation".
The other shores impacted by this plan include Pulau Jong, Pulau Hantu, Terumbu Pempang Darat, Terumbu Pempang Tengah, Terumbu Pempang Laut.
Singapore's submerged reefs are often out of sight under the high tide and thus forgotten. Let's hope Terumbu Semakau stays safe until we can visit again.
The Singapore Blue Plan 2018
Pulau Semakau and nearby islands and submerged reefs have been recommended by the Singapore Blue Plan 2018 for Immediate Conservation Priority.
The Blue Plan recommends the intertidal and subtidal marine areas of Pulau Semakau and adjacent Pulau Hantu, and Pulau Jong to be designated Marine Reserve.
