|Some lovely brown (not bleaching) corals on the rocky shore.|
A view of the natural rocky shore just off mainland Singapore, on a glorious sunny afternoon.
July 2016 where I estimate about 80% of the hard corals and 50% of the leathery soft corals are bleaching, and 10-20% of the corals have died recently. More about the 2016 mass coral bleaching in Singapore.
|Coral bleaching at St John's Island in Jul 2016|
Sandpaper coral and one small Cauliflower coral and they were not bleaching.
Pore corals are common on this shore. I did not see any that were bleaching. Most seemed alright although some had dead patches.
Merulind corals (previously Favid corals). Some colonies were totally healthy looking, others had dead patches. But none of those I saw were bleaching.
Anemone coral colonies. Some seemed alright but a few had rather pale polyps. I saw one Small goniopora coral colony which seems alright although it had dead patches. There is a bloom of Sargassum over most of the reefy parts of the shore. So I couldn't take a closer look at the corals that I saw there in the past such as Disk corals.
Omelette leathery soft corals which looked fine. I saw many Giant carpet anemones and all looked fine. Marcus found a few Magnificent anemones, and I saw a few Frilly sea anemones, all were not bleaching. All the Sea mat zoanthids I saw were not bleaching.
Cephalapod eggs on the left and nudibranch eggs on the right. A hopeful sign of life!
Nyireh laut trees. We only have a handful of these Critically Endangered trees, some here and one other growing at Sentosa. The big mother tree seems alright. And the two daughter trees nearby are also doing fine.
Tape seagrasses with long leaf blades. All of them were flowering! Some had female flowers on long stalks (left) and some had short male flowers (right).
Spoon seagrasses with tiny leaf blades are also growing well inside the artificial swimming lagoons.
Haddon's carpet anemones. I didn't see any anemone shrimps but I saw this spider crab happily crawling on top of one. It didn't seem to be trapped in the anemone.
Common sea stars. But I didn't see any other kind of sea star or sea cucumbers in the seagrass areas. There were lots of Long black sea cucumbers on the rocky shore.
construction equipment that we saw in Jul 2016 was no longer there. It was nice to see that kids were having fun on the beach earlier in the day!
What is the future of St. John's Island?
Recently, it was reported that Sentosa Development Corporation would no longer manage St John's as well as some other Southern Islands. These islands would be returned to the Singapore Land Authority (SLA). SLA said "it would reveal plans for the Southern Islands, when ready."
Let's hope SLA considers it worthwhile to consult with the community of people who care about the Southern Islands. The Islands belong to all of us and many of us stand ready to help look after and protect the islands. From the people who care about the cats on St. John's Island, people who are concerned about heritage of the Southern Islands, people who love the marine life; divers, shore explorers, fishermen, to scientists who work in the area and fish farmers who make a living here.
In an era of public consultation, I do hope SLA will consider community engagement on their 'plans'.
