Toxicity: No toxicity known
Origin: South America and Cuba
Notes: Spread by: seeds with long viability, birds and animals. Vegetative fragments transported by flood waters and the sea, viable after many days in the sea. Invades/threats: Coastal areas including dune and strand areas on islands and the mainland. Notes: prickly pears were brought to Australia with the First Fleet as hosts for cochineal bugs, the source of red dye. Grown as garden ornamentals by early settlers. At the height of their rapid spread many millions of hectares of valuable grazing and agricultural land were infested. The larva of the Cactoblastis moth has largely brought prickly pears under control except in coastal area where it is not effective. Fruit are edible but require careful handling. Opuntia stricta appears to be the only species that occurs in this district. It and other species of prickly pear, O. aurantiaca, O. monacantha, O. tomentosa and O. streptacantha, are Category 3 restricted invasive plants under the Biosecurity Act 2014. They must not be given away, sold, or released into the environment without a permit. The Act requires everyone to take all reasonable and practical steps to minimise the risks associated with invasive plants and animals under their control. This is called a general biosecurity obligation (GBO).
