To help protect our environment:
Still or slow-moving freshwater bodies.
Vegetative spread from stem and leaf fragments. Human-mediated dispersal through deliberate plantings.
Forms thick mats, smothering vegetation, impeding drainage, and interfering with recreational activities. Potential to impact on the mauri of wai māori.
Do not attempt to undertake control of this species. Please report to Auckland Council.
CAUTION: When using any herbicide or pesticide please read the label thoroughly to ensure that all instructions and safety requirements are followed.
