Today NOAA proposed listing 66 species of reef-building corals under the Endangered Species Act (ESA): 59 species in the Pacific (7 as endangered, 52 as threatened); 7 in the Caribbean (5 as endangered, 2 as threatened). The agency is also proposing that two Caribbean species already listed be reclassified from threatened to endangered. (You can see the full species list here.)
NOAA identifies 19 threats to the future of corals, including the ecological impacts of fishing and poor land-use practices. But first and foremost are three daunting problems related to the continued growth in greenhouse gas emissions and a changing climate:
Rise in ocean temperatures
Corals are biodiversity factories providing home and shelter to more than 25 percent of fish in the ocean and up to two million marine species. Their direct economic and social benefits are wide ranging, with one independent study finding they provide some $483 million in annual net benefit to the US economy from tourism and recreation and a combined annual net benefit from all goods and services of about $1.1 billion.
The annual commercial value of US fisheries from coral reefs is more than $100 million annually, with reef-based recreational fisheries generating another $100 million a year.
Following NOAA’s proposal there will be a 90-day public comment period (you can submit a comment here) including 18 public meetings (schedule here, more will be added) before the listing is finalized in late 2013.
