Once again, members of the public joined NUS Toddycats in commemorating National Day by coming together to clear marine trash from our precious mangroves – 90 volunteers cleared half a tonne of trash (573kg) in 103 trash bags from Lim Chu Kang East mangrove this year.
The cleanup was relocated to this tougher site as our usual site at Lim Chu Kang beach and mangrove has received enough tender loving care of late that it remains relatively clean – encouraging news indeed!
Before the buses from Kranji MRT with most of the buses arrived, a pre-cleanup check of the site was conducted. We identified two beautiful mangrove pit vipers in LCK East mangrove and marked off the area to ensure they would not disturbed by the cleanup crew.
The 90 volunteers were sorted into groups of 10 led by team leaders who were pushed through four insertion points into Lim Chu Kang East mangrove, slowly and carefully. Many hands make light work indeed and the small groups working hard amidst the vegetation also ensured we minimised our impact to the site.
We would not clear all of the trash that morning but the ICCS cleanup in September would take care of the rest. Meanwhile, it was good to realise see that the mangrove plant cover had improved considerably in LCK East mangrove.
I was really happy that I had NUS Toddycats with me – eleven of these experienced field biologists led small groups of volunteers deep into our plastic-ridden but precious LCK mangroves. Thanks to Amanda Tan, Xu Weiting, Kenneth Pinto, Yang Yi Yong, Fung Tze Kwan, Tan Chia Wu, Tan Kai Scene, Airani S, Adriane Lee, Teo Kah Ming & Theresa Su; also Joys Tan for handling pre-cleanup logistics.
It was a delight to see Sonneratia alba sprouting on the northern stream bank once again! We worked hard in this polluted stream to remove embedded plastic bags – the stream was still host to many crabs, fish, prawns, mudskippers and even horseshoe crabs, which still mate in the area.
Mangrover Theresa Su, the soothing sight of a capable field biologist amidst the mud!
Organic pollutants from upstream was trickling down into the stream and raising an awful smell – this stinky organic effluent must be traced back to its source and eliminated. It pollutes the north-western mangroves in many spots, not just Lim Chu Kang East mangrove.
Wheelbarrows are critically important in shifting half a ton of trash – we borrowed this from NUS CAPT, used the DBS pickup to bring to over to my RVRC office and rented a GoGoVan to transport it here in the morning – well worth all the effort! They will next be used at Tanah Merah during ICCS on 3rd September 2016.
At the Weighing Station, volunteers weight and total up the weighed trash carefully! The weight does not reflect the number of items removed (e.g. a high amount of plastics is not heavy), but provides some indication at least of the amount of trash removed.
A chain-gang of volunteers moved the accumulated half tonne of mangrove trash to the Trash Disposal Point, and thanks to the National Environment Agency’s Department of Public Cleanliness, their contractor will come at midday to help us with trash removal. All of such trash in Singapore ends up in an incineration point and its ash ultimately makes its way to the Pulau Semakau landfill the south.
What an amazing sight to behold once we were done, this is what a macro-trash free mangrove in Singapore would look like – may all our mangroves be as well-loved! #limchukang #mangrove #nationalday (Photo by Fung Tze Kwan)
Always on hand, my first aid kits were thankfully needed just for one scratch today; sharing the comprehensive advise to participants before the cleanup, the pre-cleanup recce, the safety briefing with critical emphasis at the start, site captains and experienced independents amongst the volunteers, the slow and careful movement by everyone, the thick gloves issued to everyone, and the “gloves on always” rule – all of these help keep cleanups incident-free.
Back at the Lee Kong Chian Natural History Museum at the National University of Singapore, a few of us NUS Toddycats see to the cleaning of the muddy gloves and wheelbarrows. These will be set aside to dry and then are packed away for the next cleanup! #reuse
Always head into tough terrain with some help – I was really pleased with the 11 @nustoddycats who stepped up to be site captains when summoned that morning – they kept everyone safe in the tough terrain! Here, my former honours students are lined up chronologically – Maria, sister of Theresa Su (Hons 2009), Xu Weiting (Hons 2010), Fung Tze Kwan (Hons 2011) & Amanda Tan (Hons 2012).
Hearty greetings for Singapore’ 51st National Day in the sun from the wonderful volunteers!
