| Abstract | Hudson pear (Cylindropuntia rosea (DC.) Backeb.) is an invasive cactus of Mexican origin that has naturalised in a variety of habitats in north-western NSW and continues to spread. It seriously degrades invaded land and ecosystems and has the potential to reduce the viability of agricultural enterprises and impact on the biodiversity of native fauna and flora. Cylindropuntia rosea has spines which can penetrate footwear and even vehicle tyres. The spines can cause serious injury to humans, livestock and working animals such as horses and dogs and may present a severe impediment to mustering operations. The presence of C. rosea on flood plains is particularly worrying as a major flood event could result in a significant increase in its distribution including movement into the Darling River system. Cylindropuntia rosea was first detected in Australia in the Lightning Ridge area during the late 1960s and is believed to have spread from a cactus nursery at Grawin. The current Australian distribution of C. rosea is north-western NSW (primarily around the opal mining areas of Lightning Ridge, Grawin and Glengarry and at Cumborah, although infestations have also been reported from Brewarrina, near Coonamble and Goodooga), South Australia (from the Flinders Ranges south to Morgan), in Western Australia, in the Northern Territory and in Queensland. Estimates of the area of NSW infested range from 60,000 to in excess of 100,000 hectares. Climate matching of the current Australian distribution of C. rosea using the Match Index function in CLIMEX ® indicates large areas of inland Australia have a similar climate to the current core infestations of C. rosea and are therefore potentially at risk of invasion. Control of C. rosea using herbicides is made more difficult by the types of terrain and vegetation in which infestations are located. C. rosea spreads by the movement of segments and fruit that root where they come into contact with the ground. As the plant occurs over an extremely large area it is not possible to successfully locate and destroy all potential Prospects for Hudson pear biological control in Australia |
