Other environmental pressures on the reef and its ecosystem include runoff, climate change accompanied by mass coral bleaching, dumping of dredging sludge and cyclic population outbreaks of the crown-of-thorns starfish.
The types of corals that reproduced also changed, leading to a "long-term reorganisation of the reef ecosystem if the trend continues.
Farming fertiliser runoff release nitrogen, phosphorus, and potassium into the oceanic ecosystem, and these limiting nutrients cause massive algal growth which eventually leads to a reduction in oxygen available for other creatures in a process called eutrophication.
This process conserves marine biodiversity by considering the whole ecosystem a species is in and how different species interact in the marine environment.
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.
As the worldxe2x80x99s most extensive coral reef ecosystem, the Great Barrier Reef is a globally outstanding and significant entity.
Practically the entire ecosystem was inscribed as World Heritage in 1981, covering an area of 348,000 square kilometres and extending across a contiguous latitudinal range of 14o (10oS to 24oS).
Criterion (viii): The GBR, extending 2,000 kilometres along Queensland's coast, is a globally outstanding example of an ecosystem that has evolved over millennia.
Today the GBR forms the worldxe2x80x99s largest coral reef ecosystem, ranging from inshore fringing reefs to mid-shelf reefs, and exposed outer reefs, including examples of all stages of reef development.
Biologically the unique diversity of the GBR reflects the maturity of an ecosystem that has evolved over millennia; evidence exists for the evolution of hard corals and other fauna.
At the scale of the GBR ecosystem, most habitats or species groups have the capacity to recover from disturbance or withstand ongoing pressures.
The extent and persistence of damage to the GBR ecosystem will depend to a large degree on the amount of change in the worldxe2x80x99s climate and on the resilience of the GBR ecosystem to such change.
