If you have seen or suspect the presence of african feather grass you must report the sighting to Northland Regional Council immediately

What does it look like?

African feather grass is a perennial grass that forms large clumps up to two metres tall. From November to April, it produces long, thin flower heads with distinctive yellow to purple flower and prominent bristles. When ripe, the spikelets containing the seed fall away, leaving the bare stem. The shape of the flower head distinguishes it from the fluffy flower heads of pampas grass and toe toe. African feather grass has been found in pasture, roadsides, urban areas, wasteland, swamps and stream banks.

Why is it a problem?

African feather grass can suppress low growing plants and restrict movement of animals, people and machinery. It impairs drainage and visibility along roads, creates a fire hazard and provides cover for pest species. African feather grass is very persistent (recovers quickly after being damaged), difficult to eradicate and is drought-resistant. The seeds of African feather grass are dispersed by wind, water and in animal hair or clothing (barbed bristles on the seed husk enable them to become entangled in fibres). Rhizomes are spread by machinery/cultivation or by dumping plant material/soil.

Control methods

Physical control

  • Dig out small infestations. Dispose of at refuse transfer station or burn.

Herbicide control

  • Spray (spring-autumn): glyphosate 15-20ml per litre water + penetrant (360g/l glyphosate)
  • Slash and spray regrowth (spring-autumn): haloxyfop-P-methyl 15ml per litre water  (96.8g/l Haloxyfop).

CAUTION: When using any herbicide or pesticide, PLEASE READ THE LABEL THOROUGHLY to ensure all instructions and safety requirements are followed.

Management programme

National Pest Plant Accord (NPPA), Progressive containment

National Pest Plant Accord (NPPA)

The NPPA is designed to prevent the sale, distribution and propagation of a set list of pest plants (the Accord list) within New Zealand. If allowed to spread further, these pest plants could seriously damage the New Zealand economy and environment.

Progressive containment

Progressive containment species are listed pests which are present in the region in numbers that mean eradication is not possible in the short term, but populations can be contained or reduced over time. These pests are capable of causing adverse effects to the environmental, economic, social or cultural values in Northland.

Rules

Under Section 52 and 53 of the Biosecurity Act 1993 no person can sell, propagate, breed, distribute or otherwise spread any pest in this Plan, or unwanted organism. Not complying with Section 52 or 53 is an offence under the Act, and may result in penalties noted Section 157(1).
Every person who sees, or suspects the presence of any African feather grass outside the containment areas shall immediately report the sighting to Northland Regional Council.
Where African feather grass is present on a property within the containment areas, the occupier shall develop and implement a management plan, agreed to by the Northland Regional Council, that reduces the extent of the infestation on the property and ensures that it does not spread to non-infested areas.

What is council doing about this?

If you suspect the presence of African feather grass, please contact the Northland Regional Council immediately. For infestations outside of the containment area, control will be carried out free of charge by a Biosecurity Officer or approved contractor.
