St John's Island still alive

Just minutes from the Central Business District, lies one of Singapore's last natural cliffs at St John's Island. The rocky shore and reef edge has corals. There are also seagrasses throughout, as well as rare mangrove trees on the untouched western shore, which is part of the Sisters Islands Marine Park.

A large team checks out the shores well before dawn. The corals seemed fine, seagrasses still doing well. As usual, the team make all the special finds. I will update later.

Ubin rocks still alive

A small team surveys the living rocks and seagrass meadows next to Ubin Jetty. 

We started at Thomson's Rock which was sparsely 'painted' with colourful encrusting animals. And ended up at the shore opposite the old Civil Service Chalets, where the sea fans were much reduced. The rest of the team make all the special finds. I will update later.

Less starry at a Changi shore

I made a quick solo survey of sliver of Changi shore that is seldom done by the whole team. I surveyed in Jul 2025 following a break in May 2021. 

The seagrasses seem to be doing well in the less disturbed parts of the shore. But I saw fewer and smaller sea stars. The shore was affected by seawall works all of 2024. It doesn't seem to have recovered fully from this yet.

Pulau Tekukor is alive!

Just minutes from Sentosa Cove, lies the natural reefy rocky shores of Pulau Tekukor. Including last longest natural coastal cliff in Singapore.

The corals seems fine, and coastal forest looks good. As usual, the rest of the team make all the special finds: giant clams and more! I will update later.

Pulau Semakau (North) with 3 giant clams

Pulau Semakau (North) is close to the petrochemical plants of Pulau Bukom and yet has some great reefs. A full team survey today and find 3 giant clams, a seahorse, special sea anemones and more. 

The corals seem mostly alright although there are signs of stress in some colonies. The seagrasses remain sparse.

Mangroves growing on Pulau Hantu seawall still doing well

Today, I focused almost entirely on the mangroves growing on the artificial seawalls of Pulau Hantu. Such a joy to do this with another mangrove enthusiast - thanks Kwan Siong! Amazing to see the mangroves, reefs and all kinds of marine life just opposite the huge petrochemical plants on Pulau Bukom.

We visited the large Nyireh laut growing on the seawall, and may have found another small treelet in the Southern lagoon. But sadly, someone had chopped all the saplings that settled on the Southern lagoon. My brief look suggest the corals are mostly alright. The rest of the team make all the special finds, I will update later.
