What you need to know
To help protect our environment:
- You must not breed, distribute, release or sell cotoneaster within the Auckland region.
- You must not plant cotoneaster 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 cotoneaster 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
Open scrub and coastal forest, lava flats, cliffs, forest and riparian margins, roadsides, track margins, grasslands, plantations, wasteland.
Dispersal
Seeds dispersed by birds. Human-mediated dispersal through dumping of garden waste and deliberate plantings.
Impact on environment
Form dense thickets, preventing regeneration of other plant species in coastal scrubland and grasslands.
Control
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.
Recommended approaches
Physical control
Method: Dig out.
Plant parts requiring disposal: Seeds.
Disposal options: Remove to greenwaste or landfill if practical.
Biocontrol
