A long-term water quality monitoring plan extending five years after the disposal activity is completed. [112], On 31 January 2014, the GBRMPA issued a dumping permit that will allow three million cubic metres of sea bed from Abbot Point, north of Bowen, to be transported and unloaded in the waters of the Great Barrier Reef Marine Park. Because of its natural beauty, both below and above the water’s surface, the reef has become one of the worlds most sought after tourist destinations. [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). [120] Although most of these visits are managed in partnership with the marine Tourism industry, there is a concern among the general public that tourism is harmful to the Great Barrier Reef. [125] Tourism is a major economic activity for the region. [101] The Great Barrier Reef Marine Park does not include the entire Great Barrier Reef Province. Travel and tourism website design by Jimmyweb Do you know that the Great Barrier Reef is the only living structure can be seen from outer space? That’s why we need to protect the 9,000 year old Great Barrier Reef. To achieve the objectives described above, this plan focuses on non-point sources of pollution, which cannot be traced to a single source such as a waste outlet. 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. [24]:452 as in Raine Island, the earliest example. The reef is located in the Coral Sea, off the coast of Queensland, Australia. The Great Barrier Reef has long been known to and used by the Aboriginal Australian and Torres Strait Islander peoples. The plan specifically targets nutrients, pesticides and sediment that make their way into the reef as a result of agricultural activities. The Reef Research Centre, a Cooperative Research Centre, has found coral 'skeleton' deposits that date back half a million years. Policies on cruise ships, bareboat charters, and anchorages limit the traffic on the Great Barrier Reef. Queensland is unique amongst the Australian states in that it has a number of genuine coastal [48], There are at least 330 species of ascidians on the reef system with the diameter of 1–10 cm (0.4–4 in). Great Barrier Reef's islands are simply enchanting, with the choice of over 100 islands from As the sea level rose further still, most of the continental islands were submerged. The updated version states that to date, none of the efforts undertaken to improve the quality of water entering the reef has been successful. Coral bleaching events lead to increased disease susceptibility, which causes detrimental ecological effects for reef communities. The Great Barrier Reef is said to be at least 500,000 years old or more. Their aim is to predict the fate of the Great Barrier Reef into the future by subjecting controlled samples of today's corals to the higher sea temperatures and increased ocean acidity predicted as a result of climate change 100 years from now. [80] The Great Barrier Reef is the world’s largest coral reef system and has been named as one of the Seven Natural Wonders of the World. The Great Barrier Reef is the world's largest coral reef system, extending 2,600 km (1,600 mi) over an area of approximately 344,400 square km (133,000 sq mi). In 2009, the plan was updated. [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). [citation needed], Management of tourism in the Great Barrier Reef is geared towards making tourism ecologically sustainable. We hope that this website will inspire all who visit, just as much as the Great Barrier reef has inspired us. Every outlook report follows the same judging and grading process so that information can be tracked over time. These act to reduce damage to the reef due to anchoring destroying soft coral, chipping hard coral, and disturbing sediment as it is dragged across the bottom. Only readily available information goes into the report so little of what is known about the Reef is actually featured in each outlook report. [24]:18 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. It ranges between 60 and 250 kilometres in width and has an average depth of 35 metres in its inshore waters. Many of the mature breeding adults died in the bleaching events of 2016–17 leading to low coral birth rates. 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]. It’s generally accepted that the reef begins near Bundaberg in the south and ends past Cape York Peninsula in the north. In recognition of its significance, UNESCO listed the Great Barrier Reef as a World Heritage Site in 1981. The reef is a breeding area for humpback whales, migrating from the Antarctic and is also the habitat of a few endangered species including the Dugong (Sea Cow) and large Green Sea Turtle. [24]:26 After the Coral Sea Basin formed, coral reefs began to grow in the Basin, but until about 25 million years ago, northern Queensland was still in temperate waters south of the tropics—too cool to support coral growth. online. This updated version has improved the clarity of the previous plan and targets set by that plan, have improved accountability and further improved monitoring and assessment. [53] The Whitsundays and Cairns have their own Plans of Management. 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. In 2000, an outbreak contributed to a loss of 66% of live coral cover on sampled reefs in a study by the RRC (Reefs Research Centre. Tourism on the Great Barrier Reef is concentrated in Cairns and also The Whitsundays due to their accessibility. It has been around for many millennia and is continually growing and changing. Found near islands and the mainland, the Inner Reef can be observed by snorkeling near the shore or via a quick … This process conserves marine biodiversity by considering the whole ecosystem a species is in and how different species interact in the marine environment. 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%.
