Chilean Needle Grass clippings spread by local resident on Friends of Mt Majura's Chilean Needle Grass experimental control and improvement site. Since 2004 FoMM asked local resident to discontinue spreading this highly invasive Weed of National Significance in the reserve. FoMM also asked Parks and Conservation to talk to the resident. FoMM also offered to provide trash bags and empty them which would be less costly, less time consuming and much more friendly to the environment than spraying herbicide year after year and manually remove CNG. FoMM documented the spread of CNG clippings on CNM; see for example https://canberra.naturemapr.org/sightings/4661512
