Also known as: Opuntioid cacti

Opuntia species are part of the group of Opuntioid Cacti that are Weeds of National Significance.

Profile

How does this weed affect you?

The most commonly known members of the opuntoid cacti group referred to generally as prickly pears, Opuntia species were first introduced into Australia with the first fleet, via Brazil, to establish a cochineal dye industry. By 1920 Opuntia stricta had infested 23,000,000 hectares in NSW and Queensland. Half of the infested area was so densely covered it was useless for production and was abandoned by its owners. 

Opuntia species have been declared Weeds of National Signficance in Australia. See Related weeds for details of individual Opuntia species.

Where is it found?

Prickly pears are present in all regions of NSW from the coast to the far west.

Maps and records

  • Recorded presence of Prickly pears - Opuntias during property inspections (Map: Biosecurity Information System - Weeds, 2017-2021)
    These records are made by authorised officers during property inspections under the Biosecurity Act 2015. Officers record the presence of priority weeds in their council area and provide this to the NSW Department of Primary Industries. Records reflect the presence of the weed on the date of inspection.

Biosecurity duty

The content provided here is for information purposes only and is taken from the 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 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.
For all Opuntia species except for Opuntia ficus-indica (Indian fig).
Central West Regional Recommended Measure*
The plant or parts of the plant are not traded, carried, grown or released into the environment. Land managers mitigate the risk of the plant being introduced to their land. Land managers reduce impacts from the plant on priority assets.
This Regional Recommended Measure applies to all species of Opuntia except for Opuntia ficus-indica (Indian fig)
Western Regional Recommended Measure*
Land managers mitigate the risk of the plant spreading from their land. Land managers mitigate the risk of the plant being introduced to their land. The plant or parts of the plant are not traded, carried, grown or released into the environment Land managers reduced impact of the plant on priority assets (grazing, conservation and urban areas).
This Regional Recommended Measure applies to all species of Opuntia except for Opuntia ficus-indica (Indian fig)
