LONG SWAMP RESTORATION TRIAL, DISCOVERY BAY COASTAL PARK

As you might have guessed from its name, Long Swamp is a long, narrow wetland system that is situated literally in the far south-western corner of Victoria, near the township of Nelson.

Long Swamp extends for over 15km, from the Glenelg River estuary, south-eastwards to Lake Mombeong and is bounded by coastal dunes to the south and higher undulating ground to the north. This wetland is one of the key environmental features conserved within Discovery Bay Coastal Park, is listed on the Directory of Important Wetlands in Australia, and forms part of one of the Australian Government’s identified High Ecological Value Aquatic Ecosystem (HEVAE) sites across the country.

Like many wetlands across southern Australia, the hydrology of Long Swamp has been altered (through a range of factors) since European settlement, and there has been growing concern within the local community about the current trends of change within the wetland system.

After the launch of Nature Glenelg Trust in January 2012, we began working in partnership with the local community and the agencies responsible for the management of Long Swamp, to:

  • help better understand the current values of the system,
  • document the historic and current trajectory of change, and
  • articulate future management options that are based around a sound set of principles that are guided by the scientific work undertaken.

The findings of the baseline Long Swamp Fish and Frog Study, commissioned by the Glenelg Hopkins CMA and undertaken by Nature Glenelg Trust in 2012, can be downloaded here: Long Swamp Fish and Frog Survey 2012.

As a result of the this work and other previous studies, Nature Glenelg Trust has been awarded grant funding by the Department of Environment and Primary Industries (DEPI), to undertake a hydrological restoration trial at the Nobles Rocks outlet from Long Swamp, through the installation of temporary sandbag weir structures in 2014/15.

This project has been made possible by the generous support of the Nelson Coastcare Group, Parks Victoria, DEPI, the Glenelg Hopkins CMA and a wide range of other people in the local cross-border community.

Please check the blogs below for the latest updates on the project, as well as a large amount of additional background information.

  • Natural flows return for the first time in decades to a new section of creekline at Glenshera Swamp, near Mount Compass June 26, 2020 Regular readers will be familiar with NGT’s ongoing hydrological restoration work at Glenshera Swamp, on the Fleurieu Peninsula near Mount Compass. In the previous newsletter we described recent work completed to backfill an artificial drain that was denying flow to a natural, meandering creekline that formerly carried water into the heart of Glenshera Swamp, a short distance ...
  • Your final chance to support the work of NGT before the end of financial year June 25, 2020 Outside of occasional major projects, we don’t generally talk much about public fundraising. However, with the end of financial year fast approaching, this is the one time of year when a donation to NGT can immediately be included as a deduction in your forthcoming tax return… so it is probably worth a quick mention! Over the ...
  • What do saltmarsh near Geelong, Glastonbury Abbey and wild rabbits have in common? The fascinating story of James and Thomas Austin June 25, 2020 It has been bubbling away quietly in the background for the past 12 months, but NGT are now in the final stages of an eco-hydrological assessment to evaluate restoration options for an area of important saltmarsh habitat that has been declining in condition over several decades, situated within The Spit Wildlife Reserve (near Avalon/Geelong). The ...
  • A very exciting rare visitor to the south-west of Victoria! June 25, 2020 I had moments of doubt when I wondered if this day would ever come… This is my fourth year coordinating the Orange-bellied Parrot winter counts in south-west Victoria and I must say on some days I was wondering if I ever would be lucky enough to have a confirmed sighting in our region. Four years of ...
  • Hanna Swamp: a forgotten Wallan Wallan wetland that highlights the challenges of ‘business as usual’ urban development June 25, 2020 Next month NGT will be publicly sharing another Discussion Paper on the Wallan Wallan wetlands, to follow on from one we released in March last year (2019), where we explored the risks and opportunities associated with Herne Swamp. This floodplain wetland at the headwaters of Merri Creek is within Melbourne’s northern growth corridor and, despite ...
  • Ecological burning to recover Cassinia tegulata in South Australia (Part 3) June 25, 2020 The global population of Avenue Cassinia (Cassinia tegulata) has received a further boost in management this past autumn with an ecological burn being carried out at the Blackford site. Avenue Cassinia is known to occur at just a handful of sites in our region, and NGT has been involved in boosting the population of the ...
  • Tiny art to highlight Australia’s threatened species June 25, 2020 From Orange-bellied Parrot monitoring in south-west Victoria, to the Silver Xenica translocation, to the Southern Bell Frog conservation facility, to prescribed burning to support Avenue Cassinia regeneration, and rare plant propagation in our nursery, a lot of NGT’s work centres around our local threatened species.  More than 1800 plants and animals are declared threatened species in ...
  • Photo of the month: Landholder generosity goes a long way June 25, 2020 Aquasave-NGT’s Sylvia and Nick have been out and about busy sampling for freshwater fish within the Inman Valley of the Fleurieu Peninsula, South Australia. This photo of the month captures a great moment, where one of the landowners, Baden, was able to come and join in some sampling – in the photo with him is a ...
  • Kelp, krill and whales: Reflecting on World Oceans Day 2020 this June June 25, 2020 The UN World Oceans Day on June 8th each year celebrates the major role that the ocean has in our health and that of our planet. It also draws attention to the impact that human actions have, in turn, on the health of the ocean. The world’s ocean captures about 40% of the carbon dioxide emitted by ...
  • Winter is whale season in southern Australia June 25, 2020 Late autumn sees whales returning to Australian waters to breed after spending the summer months in the Antarctic feeding grounds. The most commonly seen whales in our region are humpback and southern right whales, as well as blue whales (see this month’s post for some blue whale news) with orcas occasionally spotted too. Last week ...
