Invasive water weed detected in Nillumbik
9 August 2016
A large infestation of the State Prohibited Weed Water hyacinth has been eradicated on a property in Nillumbik Shire.
The infestation was discovered close to the Yarra River which, if undetected, could have spread into the river, creating environmental damage and negatively impacting fishing and other water activities.
Agriculture Victoria Biosecurity Officers removed 377 Water hyacinth plants from a pond on the property during June, with several thousand more plants subsequently detected and removed from a second location on the property.
Water hyacinth (Eichhornia crassipes) originates from Brazil and is extremely invasive. It can form dense mats across waterways, rendering them unusable for transport and recreation.
Infestations of Water hyacinth can also kill aquatic life by preventing light from penetrating the water and by reducing oxygen levels.
According to Agriculture Victoria Biosecurity Officer Annie Lamb, it is the community as a whole who will suffer if weeds like Water hyacinth are allowed to spread throughout Victoria.
"Water hyacinth is one of the world's worst aquatic weeds and poses a serious risk to our waterways", Ms Lamb said.
"The Victorian Government is responsible for the control of State Prohibited Weeds, including Water hyacinth, and Agriculture Victoria will remove the plants at no cost to the land owner."
Water hyacinth can be identified by its distinctive mauve flower and bulbous spongy stems. Anyone who may have seen Water hyacinth plants is urged to contact Agriculture Victoria on 136 186 and not attempt to remove the plants themselves.
