Previous status: Eradication – whole region (outside Port Hills)
New management category: Sustained control (Nelson Port Hills only)
Rationale for inclusion
Boneseed is an Eradication species across Nelson and Tasman and persists at extremely low density in coastal areas. The Port Hills area contains a significant infestation that is the main source of reinvasion to the rest of the region. While not considered achievable to eradicate. This area is. With this rule in place, active control across the Port Hills can be applied to uniformly reduce this reinvasion risk.
Description and adverse effects
A multi-branched bushy shrub, up to 3m high. It is an aggressive colonizer in coastal sites (dunes, cliffs, saltmarshes) and can displace desirable native species. Its seed can remain dormant when deeply buried for more than 10 years.
Plan Rule
Specific Rule for Boneseed in the Tasman-Nelson (Port Hills) region
Over the duration of this Plan, occupiers in the Port Hills are of Nelson, as shown on map 12, must:
- Destroy any boneseed on their land, on an annual basis, prior to the completion of flowering, unless there is a negotiated agreement in place between the Management Agency and the occupier as an alternative way to achieve this rule.
A breach of this rule is an offence under Section 154N(19) of the Act.
