Project: Balliang Grey Box Woodland Restoration

ballliang grey box restoration project

Overview:

We can transform a paddock into the largest, most southerly block of endangered Grey Box woodland in Australia. This could be a critical climate change-refuge for threatened Koalas, Brush-tailed Phascogale & Grey-headed Flying-fox & Fat-tailed Dunnart; critically endangered Swift Parrot, endangered Speckled Warbler & Barking Owl, vulnerable Diamond Firetail, Brown Treecreeper and Jacky Winter; endangered Tussock Skink & Glossy Grass Skink; endangered Fiery Jewel Butterfly and vulnerable Golden Sun Moth.

Janine Duffy, President

Location: Balliang, west of Melbourne, northwest of the You Yangs

This project was fully funded, and plantings occurred over 11 days from late June to late August 2022. 149 volunteers contributed 596 hours of planting.

Vision:

Complete restoration of a 10 hectare block of endangered Grey Box Eucalyptus microcarpa woodland at Balliang, VIC. The site was once part of a large swathe of this species-rich open eucalypt forest, but was cleared for farmland in the early 1900s.

Revegetating this site will restore the largest, most southerly block of this endangered forest type in Australia. Threatened mammals that may benefit include vulnerable Koalas, Brush-tailed Phascogale & Grey-headed Flying-fox, near threatened Fat-tailed Dunnart; threatened birds like the critically endangered Swift Parrot, endangered Speckled Warbler & Barking Owl, vulnerable Diamond Firetail, Brown Treecreeper and Jacky Winter; endangered reptiles including Tussock Skink & Glossy Grass Skink; endangered Fiery Jewel Butterfly and vulnerable Golden Sun Moth.

What/who will benefit?

The plants chosen will specifically target the needs of 16 threatened species. These include birds, mammals, reptiles and insects that are…

Critically Endangered:

Barking Owl, Black Falcon, Swift Parrot

Endangered:

Speckled Warbler, Tussock Skink, Glossy Grass Skink, Fiery Jewel Butterfly & Large Ant-blue butterfly.

Speckled Warbler: a beautiful songster of Box woodlands. Now tragically endangered in this area, as 85% of this habitat type was destroyed.

Vulnerable:

Koala*, Brush-tailed Phascogale, Grey-headed Flying-fox, Diamond Firetail, Brown Treecreeper, Little Eagle, Jacky Winter and Powerful Owl.

Diamond Firetails, vulnerable Australian finches that thrive on diverse grass seeds found in open woodlands.

We plant a wide diversity of species, genera and families of native trees, shrubs and wildflowers, to create a flourishing ecosystem. We don’t plant only quick-growing trees for carbon capture – as these are rarely useful to koalas in the long term, and we don’t plant masses of overused, widespread species, like Kangaroo Thorn/Hedge Wattle Acacia paradoxa as these can be harmful to Diamond Firetails. Our plantings typically include 30 to 40 species, carefully chosen to suit the site.

We also plant an endangered tree species: Melbourne Yellow Gum Eucalyptus leucoxylon connata. We plant many of these, and are very careful to only plant this subspecies from local provenance seed in the area it naturally occurs.

Already, on some of our earlier plantings, landowners have been approached by government authorities about releasing koalas onto the sites. This project would be very suitable for this in 3-5 years.

What’s exciting about this:

The sympathetic custodian landowners have partnered with us to plant trees since 2016, and seen new bird species colonise their farm as a result. They have agreed to exclude this paddock from grazing permanently, in order to improve their land for biodiversity. If it works – if the plantings suppress weeds, encourage koalas and self-manage – other farmers in the district may consider restoring their low productivity paddocks in this way.

PAST PLANTINGS AT THIS SITE:

2021 Planting:

Number of trees/shrubs: 365

Size of planting site: 0.3 hectares

Total Project Cost: $3650 funded by Melbourne Water and Koala Clancy Foundation donors.

Progress Report: This planting was infill into a previously-planted, heavily eroded streamside. We changed our approach, planting a lot of saltbush and salt-tolerant, hardy groundcovers.

September 2021: A bit more infill planting on the eroded creek edge.

2020 Planting:

Number of trees/shrubs: 308

Size of planting site: 1.05 hectares

Total Project Cost: $3080 funded by Melbourne Water and Koala Clancy Foundation donors.

Progress Report: This planting was the first infill on the eroded creek edge. After 3 years we could see what had worked and what hadn’t. In future we would recommend spreading topsoil before planting a site this badly damaged.

September 2020: Planting with staff only due to lockdowns
September 2020: we’re still working on the eroded parts of this creek. 2017 & 2018 plantings can be seen in the background
September 2020: bad erosion that destroys topsoil is a long term fix. But we will keep working until we repair this creek.

2019 Planting:

Number of trees/shrubs: 500

Size of planting site: 0.406 hectares

Total Project Cost: $5000 funded by Melbourne Water and Koala Clancy Foundation donors.

Progress Report: Survival in this part of the creek has been very high, and growth too, but here topsoil was present and in good condition.

July 2019: Planting day
September 2020: the 2019 plantings looking great after just 1 year
September 2021: The same site two years later. Survival in this area has been very high.

2018 Planting:

Number of trees/shrubs: 800

Size of planting site: 0.629 hectares

Total Project Cost: $8000 funded by Melbourne Water and Koala Clancy Foundation donors.

Progress Report: Terrific growth of Acacias & Eucalypts along the banks of the creek where topsoil had not been eroded.

July 2018: planting just completed
October 2021: showing growth of 2018 plantings. The hard work has been done by these plants, and future natural regeneration will occur.

2017 Planting:

Number of trees/shrubs: 600

Size of planting site: 1.2 hectares

Total Project Cost: $6000 funded by Melbourne Water and Koala Clancy Foundation donors.

Progress Report: We are pleased with the results of this early planting, though survival is quite mixed. Eroded, bare patches still exist in the creek bed, but the banks are growing well. To structurally transform flat, windswept pasture-grass farmland into an ecosystem with layers is a huge achievement.

2016 Planting:

Number of trees/shrubs: 100

Size of planting site: 0.3 hectares

Total Project Cost: $1000 funded by Melbourne Water and Koala Clancy Foundation donors.

Progress Report: One of our first-ever plantings, this site was infill on a previously-planted corridor.
