The agencies charged with managing the country’s invasive species could not have done their job this year if it wasn’t for the public reporting of their sightings of species of concern, according to the New Zealand Biosecurity Institute.
Institute President, Dr Diane Fraser, said it is reports from the New Zealand public that has so far helped authorities with the identification of major invasive threats this year.
She praises members of the public for reporting sightings of the recently detected yellow-legged hornets, the invasive freshwater gold clams and Caulerpa, the invasive seaweed, which have been crucial in assisting the appropriate agencies in their control efforts of these highly impactful species.
Dr Fraser said that these agencies need all the help they can get this summer in their efforts to protect New Zealand.
She encourages everyone to be constantly vigilant throughout the summer and the rest of the year so that these invasive species can be managed.
If any member of the public finds unusual plants or animals, she asks that these are reported to the Ministry for Primary Industries on their Pest Hotline (0800 80 99 66).
Dr Fraser said that other simple actions kiwis can do are: clean and dry all recreational gear, including footwear, bikes, boats and other water craft, dispose of garden waste appropriately, and be responsible pet owners. These simple actions can help stop the spread of harmful pests and diseases and protect the environment.
The New Zealand Biosecurity Institute is the professional networking organisation for people involved in all aspects of biosecurity including pest animal and plant management, and border control. Its members work for research organisations, educational institutions, regional councils, government departments and private organisations. All are involved in protecting Aotearoa from invasive species.
