A small team of volunteers did our annual health check on the northern shores of Chek Jawa with permission from NParks.
There were lots and lots of trails on the seaward side of the northern sand bar.
Kelvin's video of the bird. The team dug its legs out of the sand and it flew away. They tried to dig (carefully) down to see why it was trapped in the sand and couldn't find anything. Joleen Chan saw a similar situation during our survey on Dec 2019. Which she submitted to Singapore Biodiversity Records at the Lee Kong Chian Natural History Museum. Here's her report.
As usual, there were many shorebirds feeding on the shore, and also pooping. Studies have shown that shorebird poop helps seagrasses to grow, and in the process heal damaged seagrass meadows. This photo of shorebirds with the Changi Airport tower is perfect for the story of how Singapore is central to international shorebird travel - While Changi Airport is well known as an international travel hub, Singapore has long been an important stopover for shorebirds that travel thousands of kilometers every year.
Dec 2021, we saw lots of moon snails of various kinds. The most abundant were Ball moon snails, Tiger moon snails and many sand collars, which are the egg mass created by mama moon snails. I also saw the Naked moon snail. Sadly, we didn't come across Button snails - we saw these in large numbers on our last survey. We didn't come across other predatory snails common in our other sandy shores: like olive snails, bonnet snails or fig snails. These snails have not been commonly seen on our previous surveys either. But there were lots of Noble volutes - I saw one eating a clam. Also lots of Cake sand dollars and Straw tube worms.
Dec 2021, we still didn't see any Haddon's carpet anemones on the seaward facing part of the northern sand bar. They used to be quite common here. But we were relieved to see a few on the inner lagoon. We saw only a few Cerianthids, also some Pink warty sea cucumbers and large Garlic bread sea cucumbers.
Dec 2021. So the northern sand bar appears even more enormous than in the past.
Spoon seagrass (small and large leaves) and Needle seagrass with narrow leaves. I only saw some Fern seagrass in near the sourthern sand bar. Smooth ribbon seagrass continues to flourish and have taken over the southern sand bar and large parts of the southern area.
What is the fate of Chek Jawa?
Chek Jawa and Pulau Sekudu is slated for reclamation in the Long-Term Plan Review. The plan includes a road link (black line) from the mainland jumping off at Punggol, crossing to Pulau Ubin through Chek Jawa to jump off to Pulau Tekong before circling back to the mainland on Changi East. Proposed reclamation (in yellow) will bury Pasir Ris shores, Pulau Sekudu and Chek Jawa as well as a large stretches of Changi Beach.
The Singapore Blue Plan 2018
Among the Proposed Areas for Immediate Conservation Priority, the Singapore Blue Plan 2018 proposes that the intertidal and subtidal marine areas of Pulau Ubin to be designated Marine Reserve.
