The thing is, you can still find Acropora palmata growing everywhere, but it’s usually just a small remnant, a large encrustation or one poorly developed branch just trying to hang on to life. Threats to elkhorn coral include disease, coral bleaching, predation, climate change, storm damage, and human activity. Throughout its range, it has become more and more rare, and scientists now consider it to be critically endangered (very highly vulnerable to extinction). In October 2009, the Center launched an effort to gain endangered listing for 83 additional corals. Thankfully, on our recent visit to the Dominican Republic, we had a nice refresher on why this coral is so special when it is covering a nice spread of wave-washed shallow reef. Once the most abundant and important reef-building corals in Florida and the Caribbean, elkhorn corals have declined by more than 90 percent in many areas, mainly as a result of disease and “bleaching. Acropora palmata, the Elkhorn Coral, is the quintessential Caribbean Coral Reef species.

Unfortunately, the risk of shipgrounding on big ‘trees’ of Acropora palmata is a long forgotten memory. Thanks to a scientific petition the Center submitted, elkhorn and staghorn corals gained federal legal protection in 2006, becoming the first species listed under the Endangered Species Act because of vulnerability to global warming.

Thankfully, seeing and documenting the Caribbean’s lesser known corals was a complete success, and several dives at some key sites brought us face to face with a veritable catalog of rare living corals. Our site uses cookies. The number one threat for coral reefs globally is climate change. His primary interest is in corals which Jake pursues in the aquarium hobby as well as diving the coral reefs of the world. On March 3, 2005, we determined that elkhorn and staghorn corals were likely to become endangered within the foreseeable future throughout their entire ranges, and, therefore, a proposal to list the two species as threatened under the ESA was warranted (70 FR 13151; March 18, 2005). Elkhorn coral has been reported as far north as Broward County, with significant reef development and framework construction by this species beginning at Ball Buoy Reef in Biscayne National Park, extending discontinuously southward to the Dry Tortugas. The elkhorn coral is endangered mainly because of disease such as white-band disease which is believed to be the primary cause for the region wide acroporid decline during the 1980s and is still ongoing. The Elkhorn coral (Acropora palmata) is a Critically Endangered stony coral species distributed in the Caribbean, Gulf of Mexico, Florida and the Bahamas. Low genetic diversity makes coral populations more susceptible to being decimated by disease. Over the past 30 years a strong population reduction has been registered due fundamentally to the white-band disease. Endangered and Threatened Species; Proposed Threatened Status for Elkhorn Coral and Staghorn Coral, 24359-24365 [05-9222] Download as PDF Federal Register / Vol. We spent quite a bit of time working on such a Palmata Reef at Rincon, Puerto Rico nearly ten years ago, but it’s been so long since we’ve seen a good stand of this quasi-mythical coral. This list forms an objective framework which is used to set priority measures for biodiversity conservation. SUMMARY: NMFS announces the 90-day finding for a petition to list elkhorn coral (Acropora palmata), staghorn coral (A. cervicornis), and fused-staghorn coral (A. prolifera) as endangered or threatened, and to designate critical habitat under the Endangered Species Act (ESA). He is currently working with the Smithsonian Institution documenting new Caribbean deep-water species and building a one of a kind database. Genus Acropora contains three Atlantic/Caribbean species, all currently listed as threatened under the Endangered Species Act. The greatest threat to elkhorn coral is ocean warming, which cause the corals to release the algae that lives in their tissue and provides them food, usually causing death. Staghorn corals (Acropora cervicornis) are propagated within underwater coral nurseries to create a sustainable source of corals for use in coral restoration activities (inset). Since 1980 it has been estimated that 90-95% of elkhorn coral has been lost. Scientists predict that most of the world’s corals will be subjected to mass bleaching events at deadly frequencies within 20 years on our current emissions path. 88 / Monday, May 9, 2005 / Proposed Rules will incorporate biometric identifiers. Despite its rapid and dramatic decline in the 20th century, there are still some places in the Caribbean where Elkhorn coral is holding on, and still dominating certain regions of the reef. Scientists have predicted that most of the world’s coral reefs will disappear by mid-century due to global warming and ocean acidification unless carbon dioxide pollution is rapidly reduced. Indo Pacific Corals, a New Coral ID Book by Joe Rowlett, Shedding Light on Minimum PAR Values for an LPS Reef Tank. These provide important habitat for other reef animals, especially fish. A related threat, ocean acidification, caused by the ocean’s absorption of carbon dioxide, impairs the ability of corals to build their protective skeletons. This species was once so abundant that entire regions of the reef were called the ‘Palmata Zone’ and it was important to know where the palmata zones were, because their sturdy branches easily sank ships. Image of landscape, conservation, marine - 158004068 Two coral species, elkhorn (Acropora palmata) and staghorn (A. cervicornis), were liste… Sexual reproduction occurs via broadcast spawning of gametes into the water column once each year in August or September. For example, many coral diseases have emerged in recent decades, including the ‘white band’ disease that attacks all Western Atlantic species of Acropora palmata. Today, 33% of coral species are listed on the on the International Union for Conservation of Nature (IUCN) Red List of endangered species. In the early 1980s, a severe disease event caused major mortality throughout its range and now the population is less than 3 percent of its former abundance. Like staghorn coral, elkhorn coral has been listed as federally threatened under the Endangered Species Act. R. Gombarik / Shutterstock Endangered Elkhorn Coral - ABOUT Avid outdoorsman and underwater photographer, Barry Brown has spent the last 12 years documenting life above and below water in Curacao, Netherlands Antilles.

Thickets of Acropora palmata growing together in such densities have become increasingly rare in the Caribbean Sea Elkhorn coral's primary source of nutrients comes from photosynthetic algae, zooxanthellae, that live inside the coral's cells. 70, No. When corals are stressed by warm ocean temperatures, they experience bleaching – which means they expel the colorful algae upon which they rely for energy and growth.
