Marine conservation in South Australia


South Australia’s marine environment is unique. It has more diversity than the Great Barrier Reef, and about 85% of the organisms found there are found nowhere else (DEWNR 2013). Ocean upwellings, which bring nutrients to the surface, and deep canyons are important contributors to the biodiversity in this region (Nieblas et al 2009, Schmidt et al 2010, van Ruth 2010). There are also more than 100 offshore islands which are valuable conservation areas (Robinson et al 1996).

Some parts of South Australia’s marine ecosystem are stable and in good condition, but other parts are in poor condition and getting worse. This is partly due to pressure from fishing, aquaculture, shipping, and mining – all of which have management practices which could be improved (Government of South Australia 2012).

Great Barrier Reef water quality


The Great Barrier Reef (GBR) stretches for more than 2000km (Bowen & Bowen, 2002). It consists of approximately 3000 individual reefs, covers an area of 345,000km2, and is the largest coral reef ecosystem in the world (De’Ath et al., 2012). The GBR was listed as a World Heritage area in 1981 because of its “outstanding universal value”, which met all four of the World Heritage natural criteria, which were:

“to contain superlative natural phenomena or areas of exceptional natural beauty and aesthetic importance;

“to be outstanding examples representing major stages of earth’s history, including the record of life, significant on-going geological processes in the development of landforms, or significant geomorphic or physiographic features; Read the rest of this entry »
