Study Values Long-Term Riverbank Restoration
Modelling suggests substantial economic and environmental returns.
Research led by the University of Queensland assessed the costs and benefits of restoring 95 kilometres of Lockyer Creek, a major source of sediment affecting Brisbane's water supply. Measures include revegetation, fencing and off-stream watering points for livestock.
The study estimated returns of up to 400 percent through improved water quality, reduced treatment disruption, carbon storage and biodiversity gains. Researchers noted that mature trees may need about 20 years to withstand major floods, although benefits from smaller events can develop sooner.
