In 2012, Earthjustice, representing CBD, filed a lawsuit seeking greater protections from fishing for threatened coral reefs in the Caribbean. 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. elkhorn coral, endangered species, grassroots restora-tion, growth, reef rehabilitation, survival, transplanting. Today, 33% of coral species are listed on the on the International Union for Conservation of Nature (IUCN) Red List of endangered species. He is currently working with the Smithsonian Institution documenting new Caribbean deep-water species and building a one of a kind database. For example, many coral diseases have emerged in recent decades, including the ‘white band’ disease that attacks all Western Atlantic species of Acropora palmata. Staghorn and Elkhorn coral are harvested for building materials, souvenirs, jewelery, and for aquariums. The number one threat for coral reefs globally is climate change. With our primary coral photo targets acquired, we shifted our focus to shallow reef waters and set out to see what Acroporids we could find around Punta Cana. The species was listed as threatened under the U.S. 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. With a natural abundance reduced to one percent of its former glory, Elkhorn coral is truly deserving of all federal and international protections of an endangered species.

This list classifies the extinction risk of species based on criteria such as population size reduction and geographic range information. Mass bleaching events have become much more frequent and severe as ocean temperatures have risen in recent decades. A related threat, ocean acidification, caused by the ocean’s absorption of carbon dioxide, impairs the ability of corals to build their protective skeletons. Key words: Acropora palmata, Caribbean coral reefs, elkhorn coral, endangered species, grassroots restora-tion, growth, reef rehabilitation, survival, transplanting methodology. Thickets of Acropora palmata growing together in such densities have become increasingly rare in the Caribbean Sea Thankfully, we were pleasantly surprised to see that a true palmata zone still existed in Punta Cana, with healthy Elkhorn coral colonies dominating the surf zone for at least a hundred feet. Like staghorn coral, elkhorn coral has been listed as federally threatened under the Endangered Species Act.

Two coral species, elkhorn (Acropora palmata) and staghorn (A. cervicornis), were liste… 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. Researchers are sampling the corals to determine the relationship between the coral host and its algal partner using high-resolution genetic … The rising temperature of the ocean as a result of global warming is the single greatest threat to this coral species, as well as coral reefs more generally worldwide. 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 dutch, caribbean, aquatic - 158004072 Jake is interested in every facet of the marine aquarium hobby from the concepts to the technology, rare fish to exotic corals, and his interests are well documented through a very prolific career of speaking to reef clubs and marine aquarium events, and writing articles for aquarium publications across the globe.
