“A landowner with a determination to help koalas, and a grass-roots community group are working together to recreate an ecosystem. In just two years, this partnership has radically improved 1.7km of waterway leading into the most flow-stressed river in Victoria: the Moorabool River. Koalas will benefit in time, but Platypus, wombats and Wedge-tailed Eagles are already better off from the 3964 trees planted, 800m x 30m wide of invasive weed removed and 1.7km of waterway fenced off from grazing.”Janine Duffy, President Koala Clancy Foundation
Location: Gheringhap, north west of Geelong
Total project cost: $67,600
We are seeking a partners to fund the majority of this project. A government agency is funding part.
Number of trees/shrubs: 6760
Size of planting site: 8.39 hectares
To revegetate a degraded tributary of the Moorabool River and along the river itself, to provide additional high quality habitat for koalas, to slow erosion and improve water flow and quality into the Moorabool, and to protect the large remnant River Red Gum forest growing on the banks of the river on the property.
The majority of the tributary was infested with introduced Spiny Rush Juncus acutus – an invasive noxious weed. This serious environmental weed eliminates almost all other native vegetation, obstructs water flow, and harbours pest animals. The remnant old River Red Gums growing in the tributary were under threat from the weed, and some had already died. Spiny Rush is very difficult, expensive and time-consuming to control. Planning to control it began in 2020, spraying started in 2021 followed by mulching. About half the rush was killed and mulched in time for planting in winter 2021. Further spraying continued in early 2022, but mulching over winter 2022 was not possible due to water levels. By January 2023 soil moisture had reduced and mulching had been done.
PAST PLANTINGS ON THIS SITE:
Number of trees/shrubs: 843
Size of planting site: 0.764 hectares
Total project cost 2022: $8430 funded by Koala Clancy Foundation and landowner. (Note: this figure does not include the cost of Spiny Rush control, funded in full by landowner.)
Progress report: TBA
Number of trees/shrubs: 1641
Size of planting site: 3.3 hectares
Total project cost 2021: $16410 funded by Binance Charity and landowner. (Note: this figure does not include the cost of Spiny Rush control, funded in full by landowner.)
Progress report: at 28 Feb 2022 plants are thriving. The largest of them – River Red Gums and Silver Wattles – are already 1.2m high.
Number of trees/shrubs: 1020
Size of planting site: 1.132 hectares
Total project cost 2020: $10200 funded by Koala Clancy Foundation donors and landowner.
Progress report: Across most of the site, growth has been exceptional. Hop Goodenia, Sweet Bursaria, River Bottlebrush and Woolly Tea-tree are growing really well. Silver & Black Wattles are over 2m high. River Red Gums are 1 to 1.5m high. At the far southern end of the planting conditions became too salty over an area of 0.3 ha, and about 60 eucalypts have died. We will replant this area with more salt tolerant plants in 2022.
Number of trees/shrubs: 460
Size of planting site: 0.6 hectares
Total project cost 2019: $4600 funded by Koala Clancy Foundation donors
Progress report: Plants grew very fast in their first year, but in 2021 the River Red Gums were infested with Leafblister Sawfly (a native insect) that slowed their growth. Landowner sprayed with pyrethrum, and most have recovered and are growing again in 2022. Silver & Black Wattles and Blackwoods were never affected, and some are now 3m high.

How is wildlife benefitting:
Yellow-tailed Black-cockatoos, Superb Fairy-wrens, Red-rumped Parrots, Eastern Rosellas, Brown Falcons, Black Kites, Galahs, Straw-necked Ibis, Australasian Pipit, Red-browed Finch, Flame Robins, Yellow-faced & White-plumed Honeyeaters, Red Wattlebirds, Australian Magpies, Willie Wagtails, Black-fronted Dotterels and a family of Wedge-tailed Eagles are all using the planted sites. A newly-constructed wombat burrow has been seen.
Platypus have been seen in the Moorabool River at this location, and will be benefitting from improved water quality with the removal of Spiny Rush.
What’s exciting about this:
In just two years, we have radically improved 1.7km of waterway leading into the most flow-stressed river in Victoria. Brought together by a will to help koalas, our partnership with this landowner has caused the removal of a noxious environmental weed from 800metres of creekline, planted 3121 trees and plants, and fenced off 1.7km of waterway, protecting it from livestock grazing pressure.
The benefits will not only be to koalas, but to scores of birds, other mammals and insects.
