Save St Kilda Mangroves

Latest Update

21 January 2022 -

Senator Rex Patrick spent many months battling through the Freedom of information process to obtain this (heavily redacted) trove of documents. They show what, and when, the government knew about the deaths of mangroves as a result of waste brine leaking from the moribund salt ponds at St Kilda. The documents also reveal that there was no environmental bond taken from the operator when the mining leases were recently renewed for 21 years, raising the possibility that the public of SA may be left to foot the bill to clean up this mess.

Christmas is nearly upon us and the Alliance to Save St Kilda Mangroves thought you may all be interested in an update. How did the situation evolve, where are we now, and what do we hope for this site in the future? Well, the latter is easy. First things first. The impacting salt needs removing. Then restoration of the surrounding wetlands can start. And remediation of the damaged and damaging gypsum ponds. Finally, a proper closure plan for the rest of the mining leases. Faith spells out our "asks" clearly in the video. With State and Federal elections coming up, we would love to see our representatives of all political stripes commit to these four steps.

Coming soon! Earlier this year, a Community Vision Workshop was held to envision the future of the coastline along the southern parts of the Adelaide International Bird Sanctuary, Winaityinaityi Pangkara. The report from that workshop is due out shortly. Keep coming back to this website for updates and remember that there are even more updates, live as they happen, on our social media feeds.

The St Kilda Mangrove Die-off

What is happening?

Our beautiful tidal wetlands (mangroves and Commonwealth EPBC Act protected saltmarshes) surrounding the St Kilda Mangrove Boardwalk have been sickening and dying since mid 2020.

The nearby decommissioned gypsum ponds were filled with hyper-saline brines. Gypsum, lining the old ponds, had rotted after sitting empty for seven years and now the ponds are leaking and mobilising acidic materials from underneath the gypsum crust.

The SA Department of Energy & Mines regulate all the ponds as part of the Dry Creek Saltfields and the SA Department for the Environment manage the National Park next to the gypsum ponds.

Both departments have allowed this catastrophic impact to continue unchecked, merely measuring the impact, rather than being proactive and starting efforts to halt the ongoing leakage occurring from underneath the irreparably damaged gypsum crust.

The St Kilda Mangroves need your help right now

Please sign, and share the petition for the South Australian Government to act immediately to minimise the damage done to the St Kilda Mangrove Forest through the continuing leaking of hyper-saline liquid from the adjoining gypsum ponds.

So far the impact continues, no one is admitting it is an ongoing disaster, no one is taking responsibility and the environment is losing ground (and ability to repair itself) daily. [28-12-2020]
