Restoration of two actively-eroding sections of streambank on Havilah Station
A large-scale restoration project on Havilah Station, near Collinsville, is complete.
The Station Creek restoration site consists of two highly-active sections of eroding streambank (1050m and 554m), running into the Bowen River. The sites are 2km upstream of the Bowen Developmental Road crossing.
Works carried out included:
- 1919 timber piles to abate sediment. The piles were sourced from local contractors and acquired from state forests.
- Bank battering the vertical banks to a stable grade and installed rock chute batter drains and bunds to manage the entry of overland flows through multiple existing gullies.
The sites were revegetated with hydromulch to achieve groundcover, and planting, irrigation, and maintenance of tube stock to restore riparian vegetation. Native vegetation tube stock was planted in the remediation area in late October and early November to maximise the benefit of wet season rains.
Stock exclusion fencing and grazing management will ensure the success of the project in the long term.
Engineering firm Neilly Group was contracted to design the on-ground works. Local contractors carried out the work.
Benefits of streambank stabilisation include reducing loss of land, reducing the downstream effects of sediment resulting from bank erosion and restoring the ecological function of the stream.
This project is part of the Landholders Driving Change Program funded by the partnership between the Australian Government’s Reef Trust and the Great Barrier Reef Foundation.
