Kōrero: Biosecurity



Biosecurity aims to reduce the introduction of new pests, weeds and diseases into New Zealand. Ragwort, now a common farm weed, was probably introduced accidentally with pasture grasses. It was first recorded growing wild in 1874, and rapidly spread throughout the country, especially where cattle and horses were grazed.
