What you need to know

To help protect our environment:

  • You must not breed, distribute, release or sell drooping prickly pear within the Auckland region.
  • You must not plant drooping prickly pear within the Auckland region, unless you are transferring an existing plant on your land to another location within the boundaries of the same property.
  • You must destroy any drooping prickly pear on land that you occupy if it has been planted in breach of the above rules and you are directed to do so by an authorised person.

Coastal habitats, cliffs, sand dunes, scrub, pasture, roadsides, sparse canopy.

Seed dispersed by birds. Vegetative spread from stem segments, dispersed by gravity and water. Human-mediated dispersal through deliberate plantings.

May outcompete and exclude native species in coastal ecosystems, causing substantial structural changes. May impede access to coastal areas.

Site Management

Follow up treated areas 3 times per year. Encourage natural regeneration of native plants or replant treated areas where possible after 2-3 treatments to establish dense ground cover and minimise reinvasion.
