Pest Strategy

Gardeners - are you aware that you may have plants growing in your garden that are considered pests and can be harmful to our environment?

Virtually all of New Zealand’s environmental weed species began their rampage by escaping from people’s gardens. Weeds can have devastating effects on native ecosystems and any hardy, vigorous garden plant is quite possibly an environmental disaster waiting to happen.

The National Pest Plant Accord identifies pest plants that are prohibited from sale and commercial propagation and distribution across the country.

The Accord came into effect on 1 October 2001 and is an agreement between regional councils and government departments with biosecurity responsibilities. It provides a consistent approach to managing pest plants and ensures sound, environmental outcomes for controlling and eradicating pest plants across the country.

For further information on the Pest Plant Accord and the species it includes see any of the following web sites:

Greater Wellington - The Regional Council is the local municipal authority responsible for administering and enforcing the policy regarding Plant and Animal Pests in the Tawa area.

Pest Plants are assigned a management policy category according to the severity of their impact and how widespread are the infestations which is related to the phase of its invasion into the Wellington Region. Four categories are used;

Phase 0 - Potential pest not currently in the region Vigilance
Phase 1 - Recent arrival limited in distribution Eradication
Phase 2 - Expanding in range and density Containment
Phase 3 - Widespread or Entrenched in most available habitatWidespread suppression or site led management

Occupiers have a legal responsibility to notify Greater Wellington of the presence of any “Eradication” or “Containment” (outside of the containment zone) pest found on land they occupy.

For the majority of pests included in the Strategy, the main impact is on our native biodiversity. Unfortunately, many of these pests are well established and widespread throughout the region, and it is not financially or technically possible to attempt to remove all of the pests from all of the places. For these species, the most sensible option is to manage pests of our native flora and fauna in special natural places.

In 1996 Greater Wellington established the Key Native Ecosystem (KNE) programme as a means of providing a special focus on the quality of native ecosystems with the aim of protecting indigenous biodiversity in a comprehensive selection of Key Native Ecosystems. The Redwood Bush area is included as one of the KNE areas.

In addition Greater Wellington also has a Wellington City Programme with an the aim to minimise the spread and the adverse environmental impacts of Banana Passionfruit, Cathedral Bells, Climbing Asparagus, Old Man’s Beard and Wild Ginger within Wellington City. For these species in this area it is the legal responsibility of the occupier to eradicate the pest species from their land.

The following is a complete list of the pest species currently included in the Pest Strategy and their management regime.
