ABSTRACT
The study site is a ∼200 ha Holocene sedimentary coastal plain adjacent to Cairns in tropical northern Australia. A tide excluding wall was constructed around the site in the 1970’s. Tide exclusion and intensive drainage caused the oxidation of iron-sulfides and formation of severe acid sulfate soils across the site. A remediation program commenced at the site in 2001-2002. This has involved incrementally increasing tidal inundation of acid sulfate soils.
