What you need to know

To help protect our environment:

Benthic habitats, still or slow-moving waterbodies.

Uproots plants, increases turbidity, modifies habitats, eats invertebrates. Can compete with native waterfowl, fish and kōura for resources. Can cause lakes to flip to alternative state devoid of vegetation, with turbid water dominated by phytoplankton.


Check equipment and vessels for freshwater pests, clean everything that has been in contact with the water and dry everything thoroughly.
