Yet another marine pest is taking hold in Northland.
Northland Regional Council has identified a new sea spurge (Euphorbia paralias) infestation at Kapowairua (Spirits Bay).
The weed is native to Europe, but it is likely to have arrived in New Zealand on ocean currents from Australia, where it is causing major environmental damage, displacing native plants and changing natural patterns of sand movements.
The find included more than 50 plants in a six square metre area.
The latest discovery means there are now sea spurge sites recorded in seven different areas in Northland – Poutō peninsula, the Waipoua River mouth, Mitimiti, Ahipara, Waipapakauri, Hukatere and now Kapowairua, Spirits Bay.
Anyone who thinks they have found sea spurge should report it as soon as possible using the Ministry for Primary Industries Pests-and-Diseases hotline on 0800 80 99 66.
Take clear photos and do not disturb the plants as the sap is toxic. Be aware that seeds can spread via clothing and equipment and plants can also regrow from root fragments.
