The Upper Wannon River floodplain is adjacent to the Grampians National Park in western Victoria. A large proportion of this floodplain was drained from the 1950s for agriculture and later converted to a Tasmanian Blue Gum plantation forest. Nature Glenelg Trust (NGT) has been progressively working to restore the wetlands of the floodplain across public and private land, with successful permanent works now completed at Brady Swamp and Gooseneck Swamp in the Grampians National Park.
A recently awarded Victorian Government Climate Change Innovation Grant (via DELWP) is funding major on-ground works over the next two years that will see Walker Swamp transformed into a community demonstration site for sustainable floodplain restoration and management; by removing the plantations and reversing artificial drainage across the more than 440 hectares of land now owned by Nature Glenelg Trust.
These activities will restore natural river floodplain function, recreating wetland habitats for threatened and iconic species, like the Growling Grass Frog and Brolga. The works will also buffer the site against climate change, by retaining significantly more water in the landscape in the future.
A minor restoration trial on the deepest part of Walker Swamp has been in place since 2014, giving a taste of what is to come, but the major on-ground works as a result of NGT securing the site – including the backfilling of over 20 kilometres of artificial drains on the floodplain – are due to commence in autumn 2019. So we have an exciting year ahead!
The project is being delivered by NGT in partnership with the Glenelg Hopkins CMA and the Hamilton Field Naturalists Club, with grant funding support from the Victorian Government, and support from the wider community (including FOGGS).
FOGGS will be visiting the site on Saturday 14th September.
