[18] In March 2017, the journal Nature published a paper showing that huge sections of an 800-kilometre (500xc2xa0mi) stretch in the northern part of the reef had died in the course of 2016 due to high water temperatures, an event that the authors put down to the effects of global climate change.
In addition, approximately 400,000 years ago there was a particularly warm Interglacial period with higher sea levels and a 4xc2xa0xc2xb0C (7xc2xa0xc2xb0F) water temperature change.
[28] The shallow water reefs that can be seen in air-photographs and satellite images cover an area of 20,679xc2xa0km2, most (about 80%) of which[30] has grown on top of limestone platforms that are relics of past (Pleistocene) phases of reef growth.
[46] Nesting has not been reported, and the salt water crocodile population in the GBRWHA is wide-ranging but low density.
The draft decision also warned Australia that it will not meet the targets of the Reef 2050 report without considerable work to improve water quality.
Another key threat faced by the Great Barrier Reef is pollution and declining water quality.
[70][71][72] It is thought that the poor water quality is due to increased light and oxygen competition from algae.
A study showed that a doubling of the chlorophyll in the water leads to a tenfold increase in the crown-of-thorns starfish larvae's survival rate.
Mining company Queensland Nickel discharged nitrate-laden water into the Great Barrier Reef in 2009 and 2011 xe2x80x93 on the later occasion releasing 516 tonnes (508 long tons; 569 short tons) of waste water.
[75] Outbreaks are believed to occur in natural cycles, worsened by poor water quality and overfishing of the starfish's predators.
[81] On 3 April 2010, the bulk coal carrier Shen Nengxc2xa01 ran aground on Douglas Shoals,[82] spilling up to four tonnes of oil into the water and causing extensive damage to the reef.
The plan contains all the elements for measurement and improvements, including; long-term sustainability plan, water quality improvement plan and the investment plan for the protection and preservation of The Reef until 2050.
However, whereas the 2050 plan aims to incorporate protective measures such as improving water quality, reef restoration, killing of predatory starfish, it does not incorporate additional measures to address the root cause the problem namely climate change (which is caused by greenhouse gas emissions).
In 2001, the GBRMPA released a report about the declining water quality in the Great Barrier Reef and detailed the importance of this issue.
In response to this report, in 2003, the Australian and Queensland governments launched a joint initiative to improve the quality of water entering the Great Barrier Reef.
[105] The decline in the quality of water over the past 150 years (due to development) has contributed to coral bleaching, algal blooms, and pesticide pollution.
Their immediate goal was to halt and reverse the decline in water quality entering the reef by 2013.
By 2020, they hope that the quality of the water entering in the reef improves enough so that it doesn't have a detrimental impact on the health of the Great Barrier Reef.
To achieve these goals they decided to reduce pollutants in the water entering the reef and to rehabilitate and conserve areas of the reef that naturally help reduce water pollutants.
The updated version states that to date, none of the efforts undertaken to improve the quality of water entering the reef has been successful.
Some key achievements made since the plan's initial passing in 2003 were the establishment of the Reef Quality Partnership to set targets, report findings and monitor progress towards targets, improved land condition by landowners was rewarded with extended leases, Water Quality Improvement Plans were created to identify regional targets and identified management changes that needed to be made to reach those targets, Nutrient Management Zones have been created to combat sediment loss in particular areas, education programs have been started to help gather support for sustainable agriculture, changes to land management practices have taken place through the implementation of the Farm Management Systems and codes of practice, the creation of the Queensland Wetland program and other achievements were made to help improve the water quality flowing into the coral reefs.
A taskforce of scientists was also created to assess the impact of different parts of the plan on the quality of water flowing into the coral reefs.
They found that many of the goals have yet to be reached but found more evidence that states that improving the water quality of the Great Barrier Reef will improve its resilience to climate change.
Some examples of the water quality goals outlined by this plan are that by 2013, there will be a 50% reduction in nitrogen and phosphorus loads at the end of catchments and that by 2020, there will be a reduction in sediment load by 20%.
There are also a number of supporting initiatives to take place outlined in the plan to help create a framework to improve land use practices which will in turn improve water quality.
Through these means the governments of Australia and Queensland hope to improve water quality by 2013.
The 2013 outlook report and revised water quality plan will assess what needs to be done in the future to improve water quality and the livelihoods of the wildlife that resides there.
Potential significant harms have been identified in relation to dredge spoil and the process of churning up the sea floor in the area and exposing it to air: firstly, new research shows the finer particles of dredge spoil can cloud the water and block sunlight, thereby starving sea grass and coral up to distances of 80xc2xa0km away from the point of origin due to the actions of wind and currents.
A long-term water quality monitoring plan extending five years after the disposal activity is completed.
The outer part of the Great Barrier Reef is favoured for such activities, due to water quality.
The Great Barrier Reef (hereafter referred to as GBR) includes extensive cross-shelf diversity, stretching from the low water mark along the mainland coast up to 250 kilometres offshore.
The latitudinal and cross-shelf diversity, combined with diversity through the depths of the water column, encompasses a globally unique array of ecological communities, habitats and species.
Criterion (vii): The GBR is of superlative natural beauty above and below the water, and provides some of the most spectacular scenery on earth.
The varied seascapes and landscapes that occur today have been moulded by changing climates and sea levels, and the erosive power of wind and water, over long time periods.
The GBR Marine Park's legal jurisdiction ends at low water mark along the mainland (with the exception of port areas) and around islands (with the exception of 70 Commonwealth managed islands which are part of the Marine Park).
This is contiguous with the GBR Marine Park and covers the area between low and high water marks and many of the waters within the jurisdictional limits of Queensland.
Development and land use activities in coastal and water catchments adjacent to the property also have a fundamental and critical influence on the values within the property.
Other Queensland and Federal legislation also protects the propertyxe2x80x99s Outstanding Universal Value addressing such matters as water quality, shipping management, sea dumping, fisheries management and environmental protection.
Other key initiatives providing increased protection for the GBR include thecomprehensive Great Barrier Reef Outlook Report (and its resulting 5-yearly reporting process); the Reef Water Quality Protection Plan; the GBR Climate Change Action Plan; and the Reef Guardians Stewardship Programs which involve building relationships and working closely with those who use and rely on the GBR or its catchment for their recreation or their business.
This report also identified continued declining water quality from land-based sources, loss of coastal habitats from coastal development, and some impacts from fishing, illegal fishing and poaching as the other priority issues requiring management attention for the long-term protection of the GBR.
Further building the resilience of the GBR by improving water quality, reducing the loss of coastal habitats and increasing knowledge about fishing and its effects and encouraging modified practices, will give the GBR its best chance of adapting to and recovering from the threats ahead, including the impacts of a changing climate.
