Rope pear (Cylindropuntia imbricata)

Also known as: Devil's rope pear, prickly pear

Profile

Impact

Rope pear, native to the USA and central Mexico, was first recorded in Australia in 1911. The plant is common around mining towns in western NSW. Rope pear is a very spiny cactus which can cause injury to humans and to animals. It has the ability to form impenetrable clumps and reduce stock carrying capacity. Segments easily break off and can spread to new sites via flood waters.

Description

Much-branched spiny plant, often 2–3 m high, with rope-like segments growing at all angles to the upright branches.

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 Mandatory Measure
Must not be imported into the State or sold
All species in the Cylindropuntia genus have this requirement
Central Tablelands Regional Recommended Measure*
Land managers should mitigate the risk of new weeds being introduced to their land. The plant should be eradicated from the land and the land kept free of the plant. The plant should not be bought, sold, grown, carried or released into the environment. Notify local control authority if found.
This Regional Recommended Measure applies to all species of Cylindropuntia
Central West Regional Recommended Measure*
Land managers should mitigate the risk of new weeds being introduced to their land. Land managers should mitigate spread from their land.
This Regional Recommended Measure applies to all species of Cylindropuntia except Cylindropuntia rosea (Hudson pear)
North West Regional Recommended Measure*
Land managers should mitigate the risk of new weeds being introduced to their land. Land managers should mitigate spread from their land.
Western Regional Recommended Measure*
