What you need to know

To help protect our environment, after the RPMP has been operational for two years, you:

  • will not be allowed to breed, distribute, release or sell Canary Island ivy within the Auckland region.
  • will not be allowed to plant Canary Island 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.
  • must destroy any Canary Island 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

Native forest, roadsides.

Dispersal

Seed dispersed by birds. Vegetative spread locally. Human-mediated dispersal through dumping of garden waste.

Impact on environment

Forms dense mats, preventing native regeneration, affecting ground invertebrate communities and providing habitat for rodents. Can cause contact dermatitis.

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 2-3 treatments to establish dense ground cover and minimise reinvasion.

Recommended approaches

Physical control

Method: Dig out.

Plant parts requiring disposal: All parts.

Disposal options: Compost stems and roots in a composting weed bag or remove to greenwaste or landfill if practical.

Biocontrol

Biocontrol is currently not available for this species.

Community agrichemical control recommendations

No qualifications: Cut stump and paste freshly cut base of stems with metsulfuron gel.

Basic Growsafe certified: Cut stump and spray freshly cut base with 2g metsulfuron-methyl per 1 L of water.

Certified Handler/Experienced agrichemical user: Foliar spray with 5g metsulfuron-methyl per 10L of water and 20ml penetrant.

Caution: When using any herbicide or pesticide please read the label thoroughly to ensure that all instructions and safety requirements are followed.
