Horizons Regional Council is warning farmers to stay vigilant about invasive Chilean needle grass - which is picked to pose a billion-dollar threat to New Zealand if not controlled.
The recent expiry of the Tukituki controlled area notice regarding gravel extraction and expiry of biosecurity restrictions on the Waipawa River increases the risk of Chilean needle grass spreading to the region.
Potential pathways for the plant’s propagation include movement of contaminated stock, equipment, machinery and gravel.
Any mowing or soil-engaging equipment, machinery and vehicles used in Hawke’s Bay and moved into the Tararua or Rangitīkei districts need to be washed before being used to stop the spread of Chilean needle grass.
