Department of Primary Industry and Fisheries 238 Method: The management of Class B noxious weeds involved ground based surveys, mapping and monitoring of infestations and liaison with land managers. Results: The integrated management of parkinsonia (Parkinsonia aculeata) continued at strategic locations across the Barkly Region. Ground management of Noogoora burr (Xanthium occidentale) continued on Helen Springs, Alexandria, Epenarra and Rocklands Stations. Rubber bush (Calotropis procera) was controlled and contained at various locations throughout the Barkly Region. Integrated mesquite (Prosopis pallida) control on Brunette Downs, Austral Downs Alroy Downs and Lake Nash has reduced the number of plants significantly. PROJECT: Survey and Control of Class C (not to be introduced) Noxious Weeds Project Officers: J. McMahon, E. Conway, in collaboration with the Queensland Department of Natural Resources Location: 100 km Buffer Zone east of the Northern Territory and Queensland border. Objective: To stop the introduction of noxious weeds into the Northern Territory. Background: The project was developed when noxious weeds in Queensland were rapidly approaching the Northern Territory border. Projects involving personnel from the Northern Territory and Queensland Governments have reduced plant numbers in the buffer zone. Method: Yearly aerial surveys involving Queensland and Territory officers continue to map the movement of rubber vine (Cryptostegia grandiflora) and other noxious weeds towards the Northern Territory. Results: Isolated infestations were found this year along the Gulf coastline within 130 km of the Northern Territory border. Control programs involving Northern Territory and Queensland officers have restored the buffer zone to more than a 100 km. Weed officers continue the management of prickly acacia, mesquite and parkinsonia within the buffer zone region.
