what is the great barrier reef

The Great Barrier reef runs along the northeast coast of Queensland, Australia. [60] In 2020, a study has found that Australia's Great Barrier Reef has lost more than half of its corals since 1995 due to warmer seas driven by climate change. It has been around for many millennia and is continually growing and changing. Queensland is unique amongst the Australian states in that it has a number of genuine coastal There are two steps to this process. These forms of pollution have made the reef less resilient to climate change. What Is The Great Barrier Reef? These guidelines are nationally recognised and implemented at the local level based on the Australian policy for implementation outlined in the "Goals and Principles for the Establishment of the National Representative System of Marine Protected Areas in Commonwealth Waters". On 3 April 2010, the bulk coal carrier Shen Neng 1 ran aground on Douglas Shoals,[81] spilling up to four tonnes of oil into the water and causing extensive damage to the reef. There are also venomous sea snakes, brightly colored worms, and large algae. 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. [106] The rezoning was based on the application of systematic conservation planning techniques, using marxan software. The Great Barrier Reef formed from a long and slow process involving the accumulation of organic materials, such as stone, plants and animals and shells of dead corals. the length and breadth of the Great Barrier Reef and beyond. The first step is to identify regional conservation priorities in the five (currently) different marine regions. The science behind this claim is wrong … but no-one wants to remedy the problem. The reef is located in the Coral Sea, off the coast of Queensland, Australia. Many of the mature breeding adults died in the bleaching events of 2016–17 leading to low coral birth rates. 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. [116] This fee ends up being 20% of the GBRMPA's income. The types of corals that reproduced also changed, leading to a "long-term reorganisation of the reef ecosystem if the trend continues. What’s the Great Barrier Reef? Found near islands and the mainland, the Inner Reef can be observed by snorkeling near the shore or via a quick … It has moved and morphed over the years and was first encountered by humans 40,000 years ago when A… The Great Barrier Reef is a diverse region offering the popular detinations while at the same time, still allowing the visitor to escape to remote isolation. The Great Barrier Reef Marine Park was created in 1975 through the Great Barrier Reef Marine Park Act. [111], In December 2013, Greg Hunt, the Australian environment minister, approved a plan for dredging to create three shipping terminals as part of the construction of a coalport. Also quantitative targets have been made to critically assess whether targets are being met. The announcement of the grant was subject to backlash as the grant had avoided proper tender and transparency processes. [84] The Queensland "shark control" program uses shark nets and drum lines with baited hooks to kill sharks in the Great Barrier Reef – there are 173 lethal drum lines in the Great Barrier Reef. [6] This reef structure is composed of and built by billions of tiny organisms, known as coral polyps. The Reef’s Outstanding Universal Value remains intact A maze of 3000 coral reefs and 1050 islands, the Great Barrier Reef covers an area the size of Italy and stretches 2300 … 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. [24]:18 The northern islands have 300–350 plant species which tend to be woody, whereas the southern islands have 200 which tend to be herbaceous; the Whitsunday region is the most diverse, supporting 1,141 species. [13] It employs approximately 2000 people, and fishing in the Great Barrier Reef is pursued commercially, for recreation, and as a traditional means for feeding one's family. That’s why we need to protect the 9,000 year old Great Barrier Reef. 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. [24]:158–160, Wonky holes can have localised impact on the reef, providing upwellings of fresh water, sometimes rich in nutrients contributing to eutrophication. A closer encounter with the Great Barrier Reef’s impressive coral gardens reveals many astounding underwater attractions including the world’s largest collection of corals (in fact, more than 400 different kinds of coral), coral sponges, molluscs, rays, dolphins, over 1500 species of tropical fish, more than 200 types of birds, around 20 types of reptiles including sea turtles and giant clams over 120 years old. Each assessment is judged by these criteria and given a grade. At around that time, sea level was 120 metres (390 ft) lower than it is today.

In 1999, the Australian Parliament passed the Environment Protection and Biodiversity Conservation Act, which improved the operation of national environmental law by providing guidance about regional biodiversity conservation priorities. Areas without tourism platforms have 14 out of 9,468 (1.1%) diseased corals versus areas with tourism platforms that have 172 out of 7,043 (12%) diseased corals. [78] Farming practices damage the reef due to overgrazing, increased run-off of agricultural sediments, nutrients and chemicals including fertilisers, herbicides and pesticides representing a major health risk for the coral and biodiversity of the reefs. One of Australia’s most remarkable natural gifts, the Great Barrier Reef is blessed with the breathtaking beauty of the world’s largest coral reef. Geological Society of Australia Special Publication, Adelaide, pp. [64], Another key threat faced by the Great Barrier Reef is pollution and declining water quality. ), Gondwana to Greenhouse: environmental geoscience – an Australian perspective. [83][84][85] In Queensland, sharks found alive on the baited hooks are shot. Travel and tourism website design by Jimmyweb [32][33] In the northern part of the Great Barrier Reef, ribbon reefs and deltaic reefs have formed; these structures are not found in the rest of the reef system. It's important to note the seafloor of the approved disposal area consists of sand, silt and clay and does not contain coral reefs or seagrass beds.[113]. The dredge spoil from the Abbot Point port project is to be dumped 24 kilometres (15 mi) away, near Bowen in north Queensland, and the approval from the Authority will result in the production of an extra 70 million tonnes of coal annually, worth between A$1.4 billion and $2.8 billion. Crescentic reefs are also found in the far north of the Great Barrier Reef Marine Park, and in the Swain Reefs (20–22 degrees south). Like protected areas on land, marine reserves are created to protect biodiversity for generations to come. Discover a diverse range of experiences in the Great Barrier Reef. 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. The Great Barrier Reef has suffered mass coral bleachings in 1998, 2002, and 2006, and some predict that it may become an annual occurrence. [8] The Queensland National Trust named it a state icon of Queensland. [96], In 1768 Louis de Bougainville found the reef during an exploratory mission, but did not claim the area for the French. Several continental and coral cay islands are now resorts, including Green Island and Lady Elliot Island. [27] A previously undiscovered reef, 500 meters tall and 1.5 km wide at the base, was found in the northern area in 2020. As a deepwater port that has been in operation for nearly 30 years, Abbot Point is better placed than other ports along the Great Barrier Reef coastline to undertake expansion as the capital and maintenance dredging required will be significantly less than what would be required in other areas. A study by Katharina Fabricius and Glen Death of Australian Institute of Marine Science found that hard corals numbers were almost double on reefs that were far from agricultural areas. None found in the Great Barrier Reef World Heritage Area are endemic, nor are any endangered. This 35 years plan, titled "Reef 2050 Plan" is a document proposing possible measures for the long-term management of the pollution, climate change and other issues that threaten the life span and value of this global heritage. 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. Our aim is to discuss the Great Barrier Reef, its history, its environment, its marine life and its spectacular destinations. 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 Great Barrier Reef Coast Marine Park is a marine protected area located in Queensland waters adjoining the Great Barrier Reef. In addition, approximately 400,000 years ago there was a particularly warm Interglacial period with higher sea levels and a 4 °C (7 °F) water temperature change. The world’s largest synchronised sex event, filmed every year on a moonlit night in the tropics, is to be live-streamed for the first time.Corals in the Great Barrier Reef are expected to release 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. Hazard identification and risk assessment, This page was last edited on 27 November 2020, at 06:35. Coral reefs are one of the most biologically diverse ecosystems on our planet. 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%. The Great Barrier Reef is a gathering of brilliant, vivid coral providing divers with the most [18] The percentage of baby corals being born on the Great Barrier Reef dropped drastically in 2018 and scientists are describing it as the early stage of a "huge natural selection event unfolding". [11][12], The Great Barrier Reef has long been known to and used by the Aboriginal Australian and Torres Strait Islander peoples, and is an important part of local groups' cultures and spirituality. ", "Number of Tourists Visiting The Great Barrier Reef Marine Park", "Understanding Great Barrier Reef visitors preliminary results", "Understanding Tourist Use of the Great Barrier Reef: The Whitsundays Visitor", "Are Coral Reefs Literally Sick of Ecotourists? [66], Fertilizers also increase the amount of phytoplankton available for the crown-of-thorns starfish larvae to consume. The green sea turtles on the Great Barrier Reef have two genetically distinct populations, one in the northern part of the reef and the other in the southern part. [20], The Great Barrier Reef is a distinct feature of the East Australian Cordillera division. Lady Elliot Island is located 1,915 km (1,190 mi) southeast of Bramble Cay as the crow flies. [24]:27 The Great Barrier Reef's development history is complex; after Queensland drifted into tropical waters, it was largely influenced by reef growth and decline as sea level changed. [124] This reef structure is composed of and built by billions of tiny organisms, known as coral The Great Barrier Reef has long been known to and used by the Aboriginal Australian and Torres Strait Islander peoples. Thus, while non-permanent platforms could be possible in some areas, overall, permanent platforms are likely a necessity. Environmental Management of Torres Strait: a Marine Geologist’s Perspective, in: Gostin, V.A. Although the route through the Great Barrier Reef is not easy, reef pilots consider it safer than outside the reef in the event of mechanical failure, since a ship can sit safely while being repaired. online. Furthermore, dredge spoil can literally smother reef or sea grass to death, while storms can repeatedly resuspend these particles so that the harm caused is ongoing; secondly, disturbed sea floor can release toxic substances into the surrounding environment.[113]. The Reefocus summit in 2008, which is also detailed in the report, came to similar conclusions. [113] Authority chairman, Dr Russell Reichelt, stated after the confirmation of the approval: This approval is in line with the agency's view that port development along the Great Barrier Reef coastline should be limited to existing ports. By around 13,000 years ago the sea level was only 60 metres (200 ft) lower than the present day, and corals began to surround the hills of the coastal plain, which were, by then, continental islands. In 2009, the plan was updated. Sydney website design by Jimmyweb The Great Barrier Reef is the world's largest reef systems, stretching along the East coast of Australia from the northern tip down to the town of Bundaberg, is composed of roughly 2,900 individual reefs and 940 islands and cays that stretch for 2,300 kilometres (1,616 mi) and cover an area of approximately 344,400 square kilometres (133,000 sq mi). The reef is a very popular destination for tourists, especially in the Whitsunday Islands and Cairns regions. When it comes to how the reef was formed, it is first important to understand what coral is exactly and its overall process. [45] Nesting has not been reported, and the salt water crocodile population in the GBRWHA is wide-ranging but low density. The plan specifically targets nutrients, pesticides and sediment that make their way into the reef as a result of agricultural activities. [48], There are at least 330 species of ascidians on the reef system with the diameter of 1–10 cm (0.4–4 in). Their immediate goal was to halt and reverse the decline in water quality entering the reef by 2013. Trying to work out where to stay at the Great Barrier Reef? [52] Five hundred species of marine algae or seaweed live on the reef,[39] including thirteen species of genus Halimeda, which deposit calcareous mounds up to 100 metres (110 yd) wide, creating mini-ecosystems on their surface which have been compared to rainforest cover. The renowned coral reef scientist, Terry Hughes, said it was logical the IUCN had moved the Great Barrier Reef into the critical category after three bleaching events in five years. Five Great Barrier Reef species of large benthic corals were found bleached under elevated temperatures, affirming that benthic corals are vulnerable to thermal stress. [28] According to the GBRMPA, the current, living reef structure is believed to have begun growing on the older platform about 20,000 years ago. Composed of almost 3,000 individual reefs, the Great Barrier Reef is sometimes called the world's largest organism, but it is more accurately the world's largest structure built by organisms. Solutions have been suggested to siphon bird waste into gutters connecting to tanks helping lower runoff that causes coral disease. The outer part of the Great Barrier Reef is favoured for such activities, due to water quality. The marine bioregional planning process came from the implementation of this law. [24], The remains of an ancient barrier reef similar to the Great Barrier Reef can be found in The Kimberley, Western Australia. [87] Also, Queensland's "shark control" program has also killed many other animals (such as dolphins and turtles) — the program killed 84,000 marine animals from 1962 to 2015, including in the Great Barrier Reef. 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. [55], The Great Barrier Reef Marine Park Authority considers the greatest threat to the Great Barrier Reef to be climate change, causing ocean warming which increases coral bleaching. A heritage management plan to protect the Catalina second world war aircraft wreck in Abbot Bay. [73], The crown-of-thorns starfish preys on coral polyps. We are passionate about Australia's great natural wonder, its vast marine life, its golden sun-kissed beaches, its warm turquiose waters and the unforgetable experiences that are waiting for all who visit. Corals are also known as coral polyps. "[19], The Great Barrier Reef Marine Park Act 1975 (section 54) demands every five years an Outlook Report on the Reef's health, pressures, and future. [48], 215 species of birds (including 22 species of seabirds and 32 species of shorebirds) visit the reef or nest or roost on the islands,[24]:450–451 including the white-bellied sea eagle and roseate tern. The Great Barrier Reef is a gathering of brilliant, vivid coral providing divers with the most spectacular underwater experience imaginable. 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. [38][39][40] More than 1,500 fish species live on the reef, including the clownfish, red bass, red-throat emperor, and several species of snapper and coral trout. [24]:452 as in Raine Island, the earliest example. [72], Farming fertiliser runoff release nitrogen, phosphorus, and potassium into the oceanic ecosystem, these limiting nutrients cause massive algal growth which leads to depletion in oxygen available for other creatures which decreases the biodiversity in the affected areas, altering the species composition. [98] One of the most famous wrecks was HMS Pandora, which sank on 29 August 1791, killing 35 men. Great Barrier Reef: Australia must act urgently on water quality, says Unesco. The Great Barrier Reef is the only natural structure that can be seen unaided from space and is home to about 9000 species. [76] As of the middle of 2004, approximately one-third of the Great Barrier Reef Marine Park is protected from species removal of any kind, including fishing, without written permission. As part of the Reef 2050 plan, an AUD$443 million grant was given to the Great Barrier Reef Foundation in 2018. [26], From 20,000 years ago until 6,000 years ago, sea level rose steadily around the world. [53] The Whitsundays and Cairns have their own Plans of Management. The Outer Great Barrier Reef refers to the part that is located around the central region of the entire Great Barrier Reef, some 60km from the shore of Cairns. The Great Barrier Reef is the largest living ecosystem in the world. [15] In October 2016, Outside published an obituary for the reef;[16] the article was criticized for being premature and hindering efforts to bolster the resilience of the reef. In recognition of its significance, UNESCO listed the Great Barrier Reef as a World Heritage Site in 1981. It can be reached within 90 minutes by most high speed boats and subsequently is accessible by both liveaboards and from dive resorts. [96], Under the Native Title Act 1993, native title holders retain the right to legally hunt dugongs and green turtles for "personal, domestic or non-commercial communal needs". Fishing also impacts the reef through increased water pollution from boats, by-catch of unwanted species (such as dolphins and turtles) and habitat destruction from trawling, anchors and nets. No new research is done to produce the report. Tourism operators also must comply with speed limits when travelling to or from tourist destinations, to prevent excessive wake from the boats disturbing the reef ecosystem. Most of the islands on the reef are found on planar reefs. The Great Barrier Reef is home to over 1,600 species of fish, and countless other animals. [5][110] In each outlook report, several assessments are required. The Queensland government and the Commonwealth have now accepted the alternative option and advice from The World Heritage Committee and will now commence dumping on land. Marine reserves are identified based on criteria written in a document created by Australian and New Zealand Environment and Conservation Council called "Guidelines for establishing the national representative system of marine protected areas", also known as just "the Guidelines". [27] The shallow water reefs that can be seen in air-photographs and satellite images cover an area of 20,679 km2, most (about 80%) of which[29] has grown on top of limestone platforms that are relics of past (Pleistocene) phases of reef growth. Great Barrier Reef suffers third mass bleaching Australia downgrades reef outlook to 'very poor' They found populations had dropped by more than … Region", "Aboriginal & Torres Strait Islander Culture & Dugongs and Turtles", "A history of exploration and research on the Great Barrier Reef", Captain Cook's Journal During the First Voyage Round the World, "Great Barrier Reef Marine Park Act 1975", "Fact Sheet – Marine Regional Bioregional Planning – The Process", "Reef Water Quality Protection Plan 2009", "Great Barrier Reef Outlook Report 2009 in Brief", "Greg Hunt approves dredging off Queensland to create huge coalport", "Dredge dumping: just because you can doesn't mean you should", "Dredge dumping banned on Great Barrier Reef", "Ecological Economics Criteria for Sustainable Tourism: Application to the Great Barrier Reef and Wet Tropics World Heritage Areas, Australia", "Summary report of the social and economic impacts of the rezoning of the Great Barrier Reef Marine Park", "Is Australia shooting itself in the foot with reef port expansions? [62], Climate change has implications for other forms of reef life—some fish's preferred temperature range leads them to seek new habitat, thus increasing chick mortality in predatory seabirds. The rivers of north eastern Australia pollute the Reef during tropical flood events. 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. The Great Barrier Reef is a mosaic of 2,900 individual reefs off the coast of Queensland in northeast Australia. Discover a great selection of accommodation, [53], In 1996, most of the tourism in the region was domestically generated and the most popular visiting times were during the Australian winter. [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. [128], coral reef system off the east coast of Australia, World Heritage Site, Satellite image of part of the Great Barrier Reef adjacent to the Queensland coastal areas of, Protection and preservation: Reef 2050 plan, Abbot Point coal port dredge dumping controversy, CS1 maint: multiple names: authors list (, Harris, P.T., 2001. [24]:185, Climate change, pollution, crown-of-thorns starfish and fishing are the primary threats to the health of this reef system. The marine park stretches over 3000km (1800 miles) almost parallel to the Queensland coast, from near the southern coastal town of Bundaberg, up past the northern tip of Cape York. [17] In March 2017, the journal Nature published a paper showing that huge sections of an 800-kilometre (500 mi) 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. [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. [10] According to a study published in October 2012 by the Proceedings of the National Academy of Sciences, the reef has lost more than half its coral cover since 1985, a finding reaffirmed by a 2020 study which found over half of the reef's coral cover to have been lost between 1995 and 2017, with the effects of a widespread 2020 bleaching event not yet quantified.
