A semi-natural wetland on the eastern edge of Batu Pahat, fed by drainage canals through old rubber and palm-oil estates. The site is locally famous for its population of Lesser Adjutant storks — known in Malay as burung botak ("bald birds") for their naked, scabby heads. These are large, ungainly wading birds, around 1.2 metres tall, and Malaysia is one of the very few places in the world where they can reliably be seen.
The storks roost on bare-branched trees along the canal and feed in the shallows. Early morning (around 7am) and late afternoon are best; binoculars help. There is no formal visitor centre — just a couple of pull-offs along Jalan Parit Labis — but the village along the road is friendly and used to occasional birdwatching visitors. Avoid weekends, when motorcycles disturb the birds.
