To help protect our environment:

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

Riparian margins, rocky sites, regenerating scrubland, forest, pasture, plantations.

Spores dispersed by wind.

May competitively displace native forest-dwelling ferns.

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.
