There are a number of woody plants growing in the wild in Marlborough and many of these are threatening our native ecosystems and productive agricultural land. With so many weedy plants out there, it is everyone's responsibility to do their bit to minimise their impact.
The following is a list of plant species including declared pest plants where there are legal obligations for landowners and agencies to undertake control and a number of other invasive plants where there is no legal requirement for landowners to intervene, however voluntarily action is encouraged.
