The National Parks Board (NParks) will be extending a barricade to a pedestrian pathway where a crocodile was spotted in Sungei Buloh Wetland Reserve over the weekend.
Nature watchers were surprised at the sight of a crocodile in the middle of the pathway and had to wait for up to half an hour before it crawled into the bushes and darted into the water.
Ms Judy Liew posted a video of the encounter on Nature Society Singapore's Facebook page, creating a hubbub online.
Ms Liew, who works in customer service support, said she had gone to Sungei Buloh on Saturday during high tide, at around 1.45pm.
"I didn't expect to see crocodiles around, as usually they will be feeding in the water during high tide."
She had walked about 300m to 500m from the visitor centre when she saw a crocodile lying across the footpath. She said groups of people on either side of the 2m-long crocodile could not cross over.
"I went on Sunday again and saw another crocodile on the pathway, but I don't know whether it's the same one," she said.
Mr How Choon Beng, director of the reserve, said yesterday that NParks monitors visitor trails daily and has been setting up barricades at sections where crocodiles were seen to prevent them from climbing onto the trail.
