Why is it a pest?
- It reduces the water table and can alter dune form through sand build up around its roots, resulting in erosion elsewhere.
- It is a prolific seeder with the potential to colonise a wide range of habitats and build an impenetrable sub-canopy.
- Seed is spread by birds, water and local seed fall.
- Spikes on the base of the fronds are hazardous to humans and animals.
Where is it found?
- Found in coastal areas, sandy soils, stream sides.
- Tolerant of a wide range of conditions, but not frost.
- Has been extensively used as a landscape plant.
What does it look like?
- A large palm that can grow to 18m tall.
- Robust trunk patterned with diamond shaped scars left by fallen leaves.
- Long arching dark green fronds on sharp spiny leaf stalks.
- Hanging clusters of creamy yellow-orange flowers, October to November.

What are the rules?
The Bay of Plenty Regional Council does not enforce the control of advisory species. It is landowner/occupier responsibility to manage these pests. Council may provide advice on how to manage or control these species if required.
How do you get rid of it?
- Dig out seedlings and small plants (all year round): dispose of material at a refuse transfer station.
- Drill and inject (all year round): drill holes at least 2.5cm deep every 10cm around trunk, near the ground, and inject each with herbicide.
- Cut and paint stumps (all year round) with herbicide. Leaves can be mulched, but dispose of trunk at refuse transfer station.
- Overall spray (spring-summer): spray new growth with herbicide.
Seedlings occasionally appear in profusion. All plants hard to kill. Follow up required at 1-2 months, respray survivors.
CAUTION: When using any herbicide or pesticide, PLEASE READ THE LABEL THOROUGHLY to ensure that all instructions and directions for the purchase, use and storage of the product, are followed and adhered to.
