Conservation Status
L. pertusa was listed under CITES Appendix II in January 1990, meaning that the United Nations Environmental Programme recognizes that this species is not necessarily currently threatened with extinction but that it may become so in the future. CITES is technically a means of restricting international trade in endangered species, which is not a major threat to the survival of L. pertusa. The OSPAR Commission for the protection of the marine environment of the North-East Atlantic have recognised Lophelia pertusa reefs as a threatened habitat in need of protection.
Main threats come from destruction of reefs by heavy deep-sea trawl nets, targeting redfish or grenadiers. The heavy metal "doors" which hold the mouth of the net open, and the "footline", which is equipped with large metal "rollers", are dragged along the sea bed, and have a highly damaging effect on the coral. Because the rate of growth is so slow, it is unlikely that that this practice will prove to be sustainable.
Scientists estimate that trawling has damaged or destroyed 30%–50% of the Norwegian shelf coral area. The International Council for the Exploration of the Sea, the European Commission’s main scientific advisor on fisheries and environmental issues in the northeast Atlantic, recommend mapping and then closing all of Europe’s deep corals to fishing trawlers.
In 1999, the Norwegian Ministry of Fisheries closed an area of 1,000 square kilometres (390 sq mi) at Sula, including the large reef, to bottom trawling. In 2000, an additional area closed, covering about 600 square kilometres (230 sq mi). An area of about 300 square kilometres (120 sq mi) enclosing the Røst Reef closed to bottom trawling in 2002.
In recent years, environmental organisations such as Greenpeace have argued that exploration for oil on the north west continental shelf slopes of Europe should be curtailed due to the possibility that is it damaging to the Lophelia reefs - conversely, Lophelia has recently been observed growing on the legs of oil installations.

Famous quotes containing the words conservation and/or status:
“The putting into force of laws which shall secure the conservation of our resources, as far as they may be within the jurisdiction of the Federal Government, including the more important work of saving and restoring our forests and the great improvement of waterways, are all proper government functions which must involve large expenditure if properly performed.”
—William Howard Taft (1857–1930)
“Knowing how beleaguered working mothers truly are—knowing because I am one of them—I am still amazed at how one need only say “I work” to be forgiven all expectation, to be assigned almost a handicapped status that no decent human being would burden further with demands. “I work” has become the universally accepted excuse, invoked as an all-purpose explanation for bowing out, not participating, letting others down, or otherwise behaving inexcusably.”
—Melinda M. Marshall (20th century)
