What you need to know

To help protect our environment:

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

Habitats

Coastal areas, cliffs, lowland forest and riparian margins, roadsides, wasteland, open areas.

Dispersal

Seeds dispersed by wind. Vegetative spread from stolons.

Impact on environment

Smothers understorey, suppresses seedling regeneration and facilitates invasive vines. Toxic to aquatic animals and terrestrial invertebrates.

Control

Site Management

Cut and pull vines away from desirable trees and native plants before foliar spraying. Follow up treated areas 3 times per year. Encourage natural regeneration of native plants or replant treated areas where possible after 4-6 treatments to establish dense ground cover and minimise reinvasion.

Method: Dig out.

Plant parts requiring disposal: All parts.

Disposal options: Remove to greenwaste or landfill if practical.
