Prickly pears - Opuntias (Opuntia species)

Also known as: Opuntioid cacti

Prickly pears (Opuntia species) are cactus plants that can invade natural areas and pastures. Opuntias must not be sold in NSW except for Indian fig Opuntia ficus-indica.

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. 

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.
