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]
