Pest PlantsTipu Orotā

Pest plants in Hawke's Bay can harm our environment and agriculture. At the Regional Council we protect Hawke's Bay against these pests.

What is the problem?

A large number of introduced plant species have naturalised in Hawke's Bay, to the extent that we have more introduced plants growing wild than our native species.

Many of these are considered weeds, but some cause serious harm to the environment or economic loss to agriculture. These serious weeds are called 'pest plants' and Hawke's Bay Regional Council has management plans in place, developed with community input, to meet the requirements of the Biosecurity Act 1993.

The strategy's objectives are to:

  • reduce the density and extent of pest plants,
  • increase awareness of the public of the need to recognise and control these pests, and
  • ensure that plant pests listed in the strategy are not imported into the region, sold or distributed.

Gardeners might call a weed “a plant in the wrong place” but many weeds can have serious impacts on native bush, animals, pasture and people’s lifestyles. A good reference for identifying weeds is on our pest hub or on the Weedbusters website.

What you can do to help

​Control all plant pests on your property

Destroy any plants shown in this web site that are on your property, and as they appear in future.

Dispose of plant pests safely

The best way to dispose of unwanted  pest plants is to compost, or dispose of them at an approved landfill or transfer station for deep burial. Root fragments, cuttings and seed heads can rapidly establish new plant pest infestations if they are dumped in areas such as native bush, stream banks, and along roadsides. They are also dispersed by birds, animals, wind and water and in the right conditions grow quickly, smothering native vegetation.

Prevent the spread of new plants

From time to time plants come into the region which quickly establish and can become pest plants.

​We rely on Hawke's Bay residents to be our eyes and ears looking out and reporting unusual organisms so we can respond immediately. Whether you are a landowner, lifestyle property owner or urban resident, there are pest plants that will require dealing with at some time or another.

Plant pests & management programmes

Under our Regional Pest Management Plan each each plant falls in to one of the following management programmes:

Sustained control - To provide for ongoing control of the subject, or an organism being spread by the subject, to reduce its impact on values and spread onto other properties.
Site led - The subject, or an organism being spread by the subject, that is capable of causing damage to a place is excluded or eradicated from that place, or is contained, reduced, or controlled within the place to an extent that protects the values of that place.
Eradication - To reduce the infestation level of the subject, or an organism being spread by the subject, to zero levels in an area in the short to medium term.
Exclusion - To prevent the establishment of the subject, or an organism being spread by the subject, that is present in New Zealand but not yet established in an area.
Progressive containment - To contain or reduce the geographic distribution of the subject, or an organism, being spread by the subject, to an area over time.

Pest hub

Comprehensive information on over 170 pests and weeds can be found in our online pest hub. This gives a description, images, management programmes, related links, control methods and rules for each pest.  It also provide links to notify us about certain pests, and how to request more information about a pest.
