Singapore's canal-to-river conversion at Bishan Park boosted biodiversity by 30%
0
·1 viewsSingapore converted a 2.7-km concrete canal in Bishan-Ang Mo Kio Park into a 3-km winding natural river between 2009 and 2011. The transformation involved creating a flood plain and more diverse river habitats to support wildlife. Subsequent research recorded 26 fish species in the rehabilitated stretch, including three native species. In contrast, an untreated canal section nearby harboured only eight non-native fish species. The project stands as a notable example of urban ecological restoration delivering measurable biodiversity gains.
