List of Endangered Animals in the Coral Reef


endangered animals in the coral reef

The National Marine Fisheries Service (NMFS) petitioned to list 83 species of coral under the Endangered Species Act. The petition listed greenhouse gas emissions as the primary cause of increased water temperatures, ocean acidification, increased frequency and intensity of coastal storms, and sea level rise, all of which combine to threaten corals. Two coral species, elkhorn (Acropora palmata) and staghorn (A. cervicornis), were listed as threatened for related reasons in 2006. In September 2014, 20 of the petitioned species were officially listed as threatened, and in October 2015, an additional three coral species were listed as endangered. 

Background

In October 2009, the Center for Biological Diversity petitioned NMFS to list 83 species of coral as threatened or endangered under the U.S. Endangered Species Act. Seventy-five of the species commonly occur in the Indo-Pacific, while eight are found in the Caribbean; all of the species in the petition have been identified by the International Union for Conservation of Nature (IUCN) as either vulnerable, threatened, endangered, or critically endangered. The petition identified the following threats to corals as reasons for listing under the Endangered Species Act: mass bleaching events, destructive fishing activities, pollution, sedimentation, disease, climate change, and ocean acidification. The Center for Biological Diversity identified anthropogenic climate change caused by greenhouse gas emissions and its consequences (e.g., warmer oceans, ocean acidification, increased frequency and severity of storms, sea level rise) as the largest threats to continued survival of coral reefs. In February 2010, the National Marine Fisheries Service determined that 82 of the 83 species (all except for Oculina varicosa) listed in the petition could qualify for listing as threatened or endangered under the Act.

Implementation

NMFS collaborated with scientists to examine the 82 candidate coral species through a status review report, released in April 2012. A Biological Review Team determined that two major factors contribute to the vulnerability of the species: (1) the synergistic effects of climate (warming temperatures, coral disease, ocean acidification) and non-climate (sedimentation, nutrient loading, fishing) factors on corals; and (2) the life history, taxonomy, and abundance of individual species. In November 2012, NMFS proposed to list 66 of the 82 candidate species as threatened or endangered, and to reclassify the two reef-building coral species, elkhorn and staghorn, from threatened to endangered. Through additional review of general and species-specific information, NMFS published a final rule to list 20 of the original coral species as threatened under the Act and to retain a threatened listing status for elkhorn and staghorn. A similar process was undertaken after WildEarth Guardians submitted a petition in 2013 to list 23 coral species; in 2015, three coral species were listed as endangered under the ESA. 

Outcomes and Conclusions

To date, there are 22 coral species listed as threatened and three species listed as endangered. Threatened coral species include:

  • Acropora palmata – Elkhorn coral
  • Acropora cervicornis – Staghorn coral
  • Dendrogyra cylindrus – Pillar coral
  • Mycetophyllia ferox – Rough cactus coral
  • Orbicella annularis – Lobed star coral
  • Orbicella faveolata – Mountainous star coral
  • Orbicella franksi – Boulder star coral
  • Acropora globiceps
  • Acropora jacquelineae
  • Acropora lokani
  • Acropora pharaonis
  • Acropora retusa
  • Acropora rudis
  • Acropora speciosa
  • Acropora tenella
  • Anacropora spinosa
  • Euphyllia paradivisa
  • Isopora crateriformis
  • Montipora australiensis
  • Pavona diffluens
  • Porites napopora
  • Seriatopora aculeata

Endangered coral species include:

  • Cantharellus noumeae
  • Siderastrea glynni
  • Tubastraea floreana

For threatened species, NMFS has the authority to use regulatory measures (e.g., impose harvest limitations) to protect corals; endangered listings allow for more stringent and immediate action, including harvest restrictions and recovery plans. A unique possibility of an endangered listing is that environmental organizations may be able to file lawsuits against industry or other large emitters of greenhouse gases.
