What you need to know

To help protect our environment:

• You must not breed, distribute, release or sell Brazilian pepper tree. As Brazilian pepper tree is a National Pest Plant Accord species, these restrictions apply within the Auckland region and across the whole of New Zealand.
• You must not plant Brazilian pepper tree 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 Brazilian pepper tree 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

Wetlands, mangroves, salt marshes, riparian margins, dunes, cliffs, disturbed sites, roadsides, pasture, wasteland, urban areas.

Dispersal

Seeds are dispersed by birds, mammals and water. Vegetative spread from suckering. Human-mediated dispersal through deliberate planting.

Impact on environment

Displaces native vegetation. Allelopathic, inhibiting growth and abundance of nearby native plants.

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

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 1g metsulfuron-methyl per 1 L of water.

Certified Handler/Experienced agrichemical user: Drill and inject trees with 10g metsulfuron-methyl per 1L of water if safe to do so. Drill 18mm holes (tangentially angled downwards) in a spiral up the trunk.

For 50mm stems drill one hole. For 100mm stems drill two holes. For larger stems drill holes 150mm apart. Foliar spray seedlings with 5g metsulfuron-methyl per 10L of water and 20ml penetrant.
