The “bricks” in the reef framework are formed by the calcareous remains of the tiny creatures known as coral polyps and hydrocorals, while the “cement” that binds these remains together is formed in large part by coralline algae and bryozoans. [104] 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. 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 80 km away from the point of origin due to the actions of wind and currents. A world heritage listed, natural inspiration. [66], Fertilizers also increase the amount of phytoplankton available for the crown-of-thorns starfish larvae to consume.

[24]:185, Climate change, pollution, crown-of-thorns starfish and fishing are the primary threats to the health of this reef system. Each assessment is judged by these criteria and given a grade. These forms of pollution have made the reef less resilient 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%.

[98] One of the most famous wrecks was HMS Pandora, which sank on 29 August 1791, killing 35 men. The Great Barrier Reef Marine Park Authority (GBRMPA) stated "We have strongly encouraged the company to investigate options that do not entail releasing the material to the environment and to develop a management plan to eliminate this potential hazard; however, GBRMPA does not have legislative control over how the Yabulu tailings dam is managed". [35][36], The Great Barrier Reef supports an extraordinary diversity of life, including many vulnerable or endangered species, some of which may be endemic to the reef system. [89], 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). ), Gondwana to Greenhouse: environmental geoscience – an Australian perspective. Solutions have been suggested to siphon bird waste into gutters connecting to tanks helping lower runoff that causes coral disease. [39] Most nesting sites are on islands in the northern and southern regions of the Great Barrier Reef, with 1.4 to 1.7 million birds using the sites to breed. Lady Elliot Island is located 1,915 km (1,190 mi) southeast of Bramble Cay as the crow flies. It has been characterized, somewhat inaccurately, as the largest structure ever built by living creatures. [24]:18, Fringing reefs are distributed widely, but are most common towards the southern part of the Great Barrier Reef, attached to high islands, for example, the Whitsunday Islands. [83][84][85] In Queensland, sharks found alive on the baited hooks are shot. [66], Mining company Queensland Nickel discharged nitrate-laden water into the Great Barrier Reef in 2009 and 2011 – on the later occasion releasing 516 tonnes (508 long tons; 569 short tons) of waste water. According to corresponding approval documents, the process will create around 3 million cubic metres of dredged seabed that will be dumped within the Great Barrier Reef marine park area. As part of the Reef 2050 plan, an AUD$443 million grant was given to the Great Barrier Reef Foundation in 2018. The rivers of north eastern Australia pollute the Reef during tropical flood events. [24]:37, The land that formed the substrate of the current Great Barrier Reef was a coastal plain formed from the eroded sediments of the Great Dividing Range with some larger hills (most of which were themselves remnants of older reefs[26] or, in rare cases, volcanoes[24]:26). Boat sizes range from dinghies to superyachts. [101] The Great Barrier Reef Marine Park does not include the entire Great Barrier Reef Province. The water environment of the Great Barrier Reef is formed by the surface water layer of the southwestern Pacific Ocean. The reef’s health, however, is also threatened by other factors; some marine scientists noted that coral coverage on the reef fell by nearly 50 percent between 1985 and 2012 as a result of damage caused by coral bleaching, invasive species such as the crown-of-thorns starfish (Acanthaster planci), and tropical cyclones. Five Great Barrier Reef species of large benthic corals were found bleached under elevated temperatures, affirming that benthic corals are vulnerable to thermal stress. (Ed.
