Ecology and Environment
- The Canning River and its floodplain support diverse riparian vegetation, including banksia woodlands and wetlands that provide habitat for numerous bird, fish, and invertebrate species.
- The river is subject to water quality monitoring and management by the Department of Water and Environmental Regulation to address issues such as nutrient runoff, sedimentation, and invasive species.
Human Use

- Infrastructure: Several bridges cross the river, including the Canning Bridge on the Great Eastern Highway and various local road bridges.
Conservation
- Much of the river’s upper catchment lies within protected reserves, and the Canning River Regional Park aims to preserve natural habitats while providing public access.
- Ongoing restoration projects focus on improving water quality, rehabilitating native vegetation, and managing stormwater impacts.
