REEF PROTECTION

Do not take or buy any marine products from the Indonesia ocean. The animals are important for the sensitive ecological balance of the reef and the health of the nutrient-poor reef system.
The theft of corals, shells, turtels, fish or other products are all improtant to let nutrients in the reef for the other animals and plants.
Otherwise this will destroy the marine habitat and deplete slow-growing species and their reproductive population.
Our dive center AMED SCUBA take care about this.

Coral Watchdog Calls for Plan to Counter Bleaching

Denpasar – Urgent action must be taken to prevent the worsening impact of bleaching on Bali’s coral reefs, the lobby group Reef Check Indonesia Foundation (RCIF) said this week.
FCIF said it had made a rapid assessment of reefs along a 120 kilometre stretch of coastline from Pemuteran in Buleleng to Amed in Karangasem after receiving a report from fishermen at Tejakula in Bali’s remote northeast.
The assessment found that Amed was most affected. Bleaching there covered 40 percent hard coral bleach.
RCIF has called for a six point action plan to be implemented to minimise further damage to reefs from bleaching, which is most often blamed on high water temperatures. During the assessment period water temperatures of 29-30°Cwere recorded in reef areas. Coral specialist Naneng Setiasih, who is chairwoman of RCIF, said the extent of bleaching found so far demanded a collaborative effort to manage its impact.
Nineteen types of hard coral and four varieties of soft coral were found to be affected (four types of hard coral were several affected). RCIF plans a further assessment this month to expand its data base on coral bleaching and identify areas in need of urgent remedial action.
It has put forward a six-point action plan to reduce immediate risk to coral:
stricter management of preserved areas to reduce violations
Banning destructive fishing methods such as blasting and poisoning
Clearing algae from dead coral so it can rejuvenate
Taking action (including clearing algae) to reduce feeding areas for herbivorous fish.
Diver education to minimise contact with coral
Volunteer monitoring of reefs with reports to Reef Check.

In southern Bali, a 2005 survey of coral either side of Ngurah Rai International airport found 75 percent of hard coral tested was affected by bleach. A further survey the following year found soft coral was absent from tin the area.
RCIF says Indonesia was severely affected by the global mass bleaching phenomenon of 1997-98 reporting at least half its hard coral were affected.
In Bali Barat National Park, bleaching affected 100percent of coral cover.
Around Lombok’s Gili islands, bleaching affected 90 percent of the area. Elsewhere, bleaching affected corals in Seribu National Park in East Kalimantan and at Karimunjawa, where 50-60 percent of corals died.
The economic cost of reef destruction is also very high. The degrading of coral reefs causes financial loss to the fisheries and tourism industries. Degradation of Australia’s Great Barrier Reef, blamed on global warming, was been estimated to exceed US$ 2.5 billion in a 19-year period.
One report suggest that if there is a severe coral bleaching event in the next 50 years in south-east Asia, the financial loss from product and services from fisheries, tourism and biodiversity degradation could reach $38 billion.
Rising temperatures are likely to increase the frequency of coral bleaching in some areas Some specialists, after studying the tolerance threshold of coral to bleaching over the past 100 years, predict that in 2020 coral bleaching will become an annual event. In Bali, coral reefs area critical economic asset for the tourism and fishing industries. Tourists are likely to invest less in areas with coral degeneration and reduced coral cover cuts fish numbers. One study suggests that a decrease in coral cover of more than 10 percent will cut fish numbers in the area by up to 62 percent. “We cannot avoid global warming, but together we can do something to reduce the impact on nature and on humans” Naneng Setiasih said at a media conference in Denpasar this week called to announce the results of the RCIF reef assessment.
She said a first step locally was to protect the reefs by reducing other threats and therefore giving the reefs more strength to counter bleaching. This must involve many sectors of society, from fisheries management to the tourism sector. Zoning was a part of coral reef management and technical interventions could be used to hasten rehabilitation. Bali is already developing a marine conservation area and many of the island’s eco-friendly tourism agents are helping to reduce the pressure on our reefs by removing coral predators, using mooring buoys instead of anchors, and conducting clean-up activities. According to the foundation these efforts must be tailored into a continuous network of activity which would support research to identify coral reef resistance and resilience and support development of marine conservation area management.
The foundation says it is already receiving support from government and non-government bodies. Bali’s Department of Marine Affairs and Fisheries will help by communicating information’s through the media and community groups. Departmental programs will support the coral reef research and recovery effort.
The Indonesian Maine Tourism Association of Bali will encourage both environmentally-friendly tourism and the tourist industry’s involvement in collecting coral bleaching data. Non-governmental organisations and universities in Bali, through the Mitra Bahasa consortium, a partner project focused on the management of coastal and marine resources by local government, will develop team to research coral reef management in the context of global warming. So far, the World Conservation Society ad the Bahtera Nusantar Foundation have signed up for the project.
