What you need to know

To help protect our environment, from 1 September 2021:

  • You must not breed, distribute, release or sell carex within the Auckland region.
  • You must not plant carex 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 carex 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.

Pasture, forest, forest margins, grasslands, lawns.

Sets seed, vegetative spread from rhizomes. Seeds and rhizomes dispersed by water, soil movement and attachment to birds and livestock. Human-mediated dispersal through contamination of machinery.

Competes with native grass species. Displaces pasture species, invades apple orchards and threatens horticultural plants by acting as a potential reservoir for rust fungi.

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.
