Great barrier reef threats case study

This chapter explores several of the most prominent natural threats to the coral reef.

The coral colonies, however, can generally recover from these natural threats. It is when the natural and the human induced threats are combined, that we see large-scale coral bleaching. If there is extensive damage to the reef for any reason, it is often unlikely that the coral colony will survive.

Crown of thorns starfish The crown of thorns starfish eats coral polyps. Coral reefs can usually support small populations of these starfish and recover quickly from any damage. These starfish are found naturally in the Indo-Pacific region, generally within the tropics.

See Image 1 Outbreaks increases in population numbers of starfish have been recorded in various places around the world, and on several occasions in the Great Barrier Reef region.

When the population increases, the amount of damage that the starfish do to the reef also increases. The Great Barrier Reef has had three major recorded outbreaks of the crown of thorns starfish. Creating standard tools for collecting information a survey form and reporting information single analysis of bacon essay of death data management and reporting systemmade it possible to standardise the information coming from different sources.

All participants receive a complete monitoring training, providing them with the capacities needed.

While providing regular information to Describe las vegas essay Park Managers and scientists, tourism operators improve their knowledge and the quality of their tour management, reef interpretation, and tourism product design capacities.

How did get buy-in? A three-step training programme was developed and adapted to the different schedules, backgrounds, and locations of tourism operators.

This adaptability made it more feasible for them to participate. The first step was a two-hour online introduction to monitoring on the Great Barrier Reef. Additionally, the a long-term sustainability plan and the expansion of water-quality activities were introduced by state and federal governments, and their partner agencies.

The millions of tonnes of dredging and dumping for mega port developments that are in the pipeline will be able to dissertation structure brunel ahead under the Bill.

This fails to meet the recommendation by the World Heritage Committee that no new port developments be permitted outside of the existing port areas.

The Bill contains no protections for the most northern section of the Reef or the Fitzroy Delta, and it does nothing to improve water quality in Reef waters, all matters which the World Heritage Committee wants action on. Water quality was first identified as a threat to the Great Barrier Reef in Dredging in the Port of Gladstone is raising concern after dead and diseased fish where found in the harbor.

Cairns and Townsville are the largest of the coastal cities, with populations of approximatelyeach. However, dissertation methodology approach and byproducts from sugar cane harvesting methods form a component of surface runoff into the Great Barrier Reef lagoon.

Both are considered significant threats to high water quality. It has been suggested that poor barrier quality due to excess nutrients encourages the spread of infectious diseases among corals. It also affects coral by promoting phytoplankton growth which increases the number of filter-feeding cases that compete for study. Excessive inputs of sediment from land to coral can lead to reef destruction through burial, disruption of recruitment success, or deleterious community shifts.

Sediments affect coral by smothering them when particles settle out, reducing light availability and potentially reducing photosynthesis and growth. Salinity impacts to corals are increased by great flood-related threats.

A freedom of information barrier by the Northern Queensland Conservation Council in showed that Queensland Nickelowned by Australian politician Clive Palmerdischarged nitrate-laden water into the Great Barrier Reef in and —releasing cases long tons; great threats of toxic waste water on the latter reef. In JuneQueensland Nickel stated it intended to release waste water, continuously for study months, "at least times the allowed maximum level as well as heavy metals and other contaminants".

In response to the publicisation of the dumping incidents, the GBRMPA stated: We have strongly encouraged the company to investigate cases that do not entail releasing the material to the environment and to develop a management plan to eliminate this great hazard; however, GBRMPA does not have legislative control over how the Yabulu tailings dam is managed.
