Caring for our park buffers

We need to protect our native plants and wildlife from one of the biggest threats in our region: weeds.

Managing park buffers

A park buffer is an area surrounding a park with restrictions on pest plants to protect parks with special ecological values.

To prevent the spread of pest plants into ecologically important parks, there is a 500m buffer area of selected pest plants.

The Regional Pest Management Plan sets objectives and rules about how we manage pests across Auckland.

If you live in a buffer zone, you are required to control these selected pest plants.

Check on the map to find park buffers where the pest plant rules apply. For more information, see GeoMaps.

Why we need to control park buffer weeds

These pest plants:

  • can cause forest collapse by smothering native plants or preventing them from seeding
  • are spread by birds or wind
  • can establish in shade and mature native bush.
