There were 16 FoG working parties across the three sites in 2013 following the commencement of mid-weekly events in Stirling Park and increased support from residents of Yarralumla. FoG supporters contributed over 1,000 hours in volunteer work in 2013, for a total of 3,860 since 2009. Around 1,200 m3 of woody weeds were cut, for a total of over 2,900 m3 since 2009. For more information on FoG's work see the Annual Reports.
The statistics for our volunteer efforts in 2015 showed that over 17 workparties, 192 people volunteered for 651 hours and we cut an estimated 1,053 m3 of green weeds. More importantly, we made significant progress in clearing Stirling Park of woody weeds and in replanting key areas of both Stirling Park and Yarramundi Reach.
Thanks to an ACT Government Environment Grant of $19,010 in 20013-14, FoG was able to engage contractors to spray key weeds at the three sites.
General update, February 2018
Stirling Park is in much better condition than over the past decade thanks to our efforts and those of the NCA. The last of the ‘old growth’ woody weeds should be dispatched this month. Concerted spraying of Briar Rose, Blackberry and St John’s Wort over the last two years has greatly reduced their populations. We hired a contractor this summer who has significantly reduced infestations of Fennel and Everlasting Pea. Our plantings of eucalypts, wattles and other shrubs have suffered some losses but surviving plants are thriving. Most exciting is the spread of a number of species wildflowers that we planted with Greening Australia in three plots, with wind-blown seed aiding the recolonization of weeded grassland. The Attunga Point shoreline remains largely weed free after our work to mop up after the NCA contractors, who removed major woody weeds. Happily, dense indigenous regrowth (good small bird habitat) is maturing following the removal of over 200 weed trees on the western side of Stirling Ridge three years ago.
Challenges remain, including finding the right method to kill Blue Periwinkle infestations. We keep finding more African Lovegrass and Serrated Tussock incursions. Illegal dumping of garden waste (e.g. lawn clippings and autumn leaves), especially off the Fitzgerald Street car park, is one source of these weeds: FoG wrote a letter to local residents in April 2018.
At Yarramundi Reach our battle against weed grasses (African Lovegrass, Chilean Needle Grass and Paspalum) continues. Blackberry and St John’s Work are considerably reduced. The NCA’s enhanced burning program is helping to create the right density of grass cover to allow other wildflower species to thrive.
The NCA is supporting FoG again in 2018 with a $6,000 grant to pay for volunteer training (anyone keen to help with ChenCert III or First Aid certification, please contact me), tools, plants and weed control services.
Friends of Grasslands has thanked the new Chief Executive of the National Capital Authority, Sally Barnes, and her staff for allocating additional FY19 funds to manage the significant grassy woodlands at Stirling Park and grasslands at Yarramundi Reach. In April 2018, Sally Barnes visited Stirling Park with FOG to discuss future land management. The recent Federal budget has allowed a modest increase in funding to undertake essential maintenance of the National Capital Estate. The critical management activities to be funded by the NCA in 2018-19 are:
- Remediation for the small areas affected by broken sheet asbestos in Stirling Park;
- Assessment of the safety risk posed by old and falling pine trees in Stirling Park, that are nearing the end of their lives, and the development of a management approach;
- Appropriate signage at the entrance to Stirling Park; and
- A modest increase in funding for the annual works at the woodland and grassland sites on national lands.
Stirling Park and Yarramundi Reach are already benefitting by the NCA’s investment in conservation planning, fire management and weed control. FOG considers that these additional interventions will significantly enhance conservation of cultural and natural heritage of these national lands. The work will enable greater public appreciation and use of these park lands. FOG is committed to continuing our volunteer contributions to conservation of these national lands in partnership with the NCA. We congratulate the NCA for their strategic investment in better management of these national lands.
General update November 2018
I’m still tallying up the stats but by my reckoning all three sites are substantially healthier thanks to our work:
- Stirling Park. The last woody weeds are being removed. The Attunga Point shore line has had most weeds removed. A number of weed species have declined to near negligible levels, including blackberry, honeysuckle, verbascum, fennel, asparagus and everlasting pea. Major weed infestations have been substantially reduced, including of African lovegrass, Chilean needlegrass, serrated tussock and St John’s Wort. We are trialling control of blue periwinkle. Our plantings are restoring strategic areas of grassy woodland habitat, and a lot of rubbish has been removed.
- State Circle woodlands. The site is now largely free of woody weeds, including blackberry. We have significantly reduced infestations of weed grasses and forbs, and removed a lot of rubbish.
- Yarramundi Reach. Our trial of scraping off weed seed infested and nutrient rich soil patches has commenced to test this restoration technique. We have significantly reduced infestations of weed grasses and St John’s Wort, and removed a lot of rubbish.

FoG and Save Stirling Park Group, with strong support from the NCA, are working together to eliminate the infestations in the park of cotoneaster, pyracantha (firethorn), hawthorn, olive trees, Cootamundra wattles, photinia, privet, blackberry, fleabane, St John’s wort - the list goes on. We are also planting a substantial number of species native to this area including eucalypts, kurrajongs, bursaria, acacias, small native plants and ground covers (forbes).
In January 2014, FoG President Sarah Sharp coordinated a re-survey of weeds and also threatened plants across key parts of Stirling Park. A number of the quarter hectare survey quadrats were almost completely free of woody weeds following volunteer restoration efforts since 2009, especially at the southern end of Stirling Ridge. Many thousand individual plants of a number of threatened species were counted. Sadly, other quadrats at the northern and eastern ends are still thick with weeds. The survey will help us target our future workparties to best effect.
A huge volume of woody weeds was cleared by the May 2014 workparty. Much of it was box thorn which left its mark on a few arms and legs but it was all dragged onto the pile outside the fence opposite the rusty sculpture in Alexandrina Drive. We had twenty-two workers ranging across students, Friends of Grasslands and Save Stirling Park Group. It is pleasing to note that the numbers of volunteers continues to grow as more people realise the importance of retaining Stirling Park and of removing exotic and non indigenous interlopers. These are the infestations of cotoneaster, firethorn (pyracantha), box thorn, olive trees and the Cootamundra wattles which have spread prolifically and impede the growth of species indigenous to this area. Where the Tasmanian blue gums were felled and burnt was not pretty, but Friends of Grasslands planted 200 locally indigenous trees and shrubs. As these start to grow, and other local species and wild flowers begin to re-populate the open space, the visual effect will increasingly improve for all those who walk run, learn or otherwise benefit from Stirling Park.
The ACT Government’s natural resources management program granted FoG $6000 for 2014–15 to control key weeds and do some planting at grassland sites on national lands (thank you ACT Government). FoG’s contractor sprayed Vinca, St John’s wort, african lovegrass and Chilean needle grass at the Scrivener’s Hut site, which should put it in excellent shape.
The site at Stirling Park in Yarralumla was heavily infested with Chilean needle grass and once this was sprayed in 2012 there was little remaining groundcover alive. In 2013 FoG and the Greening Australia planted 200 forbs in a section of the sprayed area. Fifteen months on (photo at right), Leucochrysum had gone from 40 to nearly 300 plants, with the second generation flowering and throwing seed. Little haloes of seedlings were starting to appear around both of the Chrysocephalum species planted. Eryngium had survived and was starting to flower. There were still issues with the roos, rabbits, a dry summer and emerging weeds, but the site was looking much better than it had two years earlier. In May 2018 FOG weed control contractors – Robert, Carl and Brent of EnviroAg – sprayed 4,250 litres of herbicide on large patches of Chilean Needlegrass on the eastern and northern lower slopes of Stirling Ridge. The weed grass sprayed is in areas where sufficient native grasses and forbs survive to recolonise the sprayed out areas.
Fire is an essential management tool for native grasslands. FoG worked with the National Capital Authority and Rural Fire Service volunteers to burn patches of Stirling Park on 16 May 2015. following our volunteer efforts to weed the Scrivener’s Hut / State Circle woodland in recent years, the NCA and Rural Fire Service conducted a control burn on the site in April 2018. The burn went very well and should aid further weed control.
In July 2014, a small team of volunteers planted about 700 seedlings of nine different forb species into grassland at Yarramundi Reach (on Lady Denman Drive, ACT). These were clustered into a few areas that had earlier been sprayed for Chilean Needle Grass and St Johns Wort under the environmental grant ‘Grassy Ecosystem Restoration on National Lands in Central Canberra’ from the ACT Government. Many places at Yarramundi Reach have good stands of grasses but very few forbs, so the addition of other common species was undertaken to improve biodiversity as well as enhancing areas of dead weeds. The work was carried out by volunteers from Greening Australia Capital Region (GA), and all the plants had been propagated in GA’s nursery facility in Aranda. Despite some dry and warm times since July, several of the species have gone on to flower and set seed in their very first season. One of the most striking has been Wahlenbergia stricta which showed up dramatically early in November with many flowers in several of the planted areas.
workparties may be cancelled in the event of extreme weather. For details and contact information for forthcoming workparties, see the current Calendar.
FoG also conducts occasional workparties at the Hall Cemetery.
