Profile
How does this weed affect you?
Prickly pears in the Austrocylindropuntia genus originate from South America, and are large succulent members of the opuntioid cacti group. Austrocylindropuntia species differ from Cylindropuntia species in that they lack papery sheaths on their spines.
Austrocylindropuntia have spines which can:
- injure people, livestock, working dogs and pets
- get stuck around the mouth of lambs or calves and stop them from feeding
- injure and sometimes kill wildlife that gets trapped in the spines
- devalue wool and hides
- prevent shearing.
Dense thickets of cacti restrict the movement of animals and people, so that:
- livestock cannot move to areas with better pasture
- mustering is difficult
- access to watering points is reduced
- recreation such as bushwalking or bird watching is restricted.
Cacti damage natural environments by excluding native plants. They also harbour pests including foxes, rabbits and fruit fly.
What does it look like?
Austrocylindropuntias have cylindrical stems with with raised tubercles (prominent oval-shaped bumps).
The leaves are fleshy, cylindrical and elongagted.
The areoles are elongated and filled with white woolly hairs and 3 or more spines. Though sometimes spines are absent on cultivated plants. Glochids (tiny barbed bristles) are present in the aeroles but very small.

The content provided here is for information purposes only and is taken from the NSW Biosecurity Act 2015 and its subordinate legislation, and the Regional Strategic Weed Management Plans (published by each Local Land Services region in NSW). It describes the state and regional priorities for weeds in New South Wales, Australia.
| Area | Duty |
|---|---|
| All of NSW | General Biosecurity Duty All pest plants are regulated with a general biosecurity duty to prevent, eliminate or minimise any biosecurity risk they may pose. Any person who deals with any plant, who knows (or ought to know) of any biosecurity risk, has a duty to ensure the risk is prevented, eliminated or minimised, so far as is reasonably practicable. |
| All of NSW |
Prohibition on certain dealings
Must not be imported into the state, sold, bartered, exchanged or offered for sale. All species in the Austrocylindropuntia genus have this requirement |

Regional Recommended Measure
* (for Regional Priority - Prevention)
