15167: Eradication of prohibited organism water hyacinth in the Serpentine River
Water hyacinth (Eichhornia crassipes) is an invasive species and has been identified as a Weed of National Significance. Its propensity to easily spread means that its control needs to be strategic and immediate. Without its control, there is risk of:
- Blocking irrigation channels and rivers
- Restricting livestock access to water.
- Destroying natural wetlands.
- Changing the temperature, pH and oxygen levels of water.
- Altering the habitats of aquatic organisms.
- Restricting recreational use of waterways.
- Reducing water quality from decomposing plants.
- Destroying fences, roads and other infrastructure when large floating rafts become mobile during flood events, and
- Destroying pastures and crops when large floating rafts settle over paddocks after flood events.
An aerial weed control operation
is being undertaken by land managers of the infested area within
the Birega Drain and Lower Serpentine River. In addition, this
project will carry out surveillance and follow
up manual removal; and aerial surveillance using drone
