745:. Climate change refers to the general warming of earth's average temperature caused by carbon emissions. Warmer atmospheric temperatures incidentally also increase water temperature. As mentioned, Elkhorn coral have special algae called zooxanthellae, living on their tissues, which provide many benefits. However, when water temperatures warm, Elkhorn coral expel their zooxanthellae. Without their zooxanthellae, Elkhorn coral first lose their prime oxygen source, then color, and then usually die. In addition, climate change increases the severity and prevalence of storms, which can decimate Elkhorn coral populations.

a diameter of 4 m (12 feet) wide and 2 m(6 feet) tall. Under stressful conditions, Elkhorn coral colonies and fragment growth slow down substantially. For example, the
Fortuna Reefer Vessel grounding site showed no measurable growth over the last ten years due to stress. Elkhorn coral create thick, interlocking groups known as thickets. Thickets provide shelter to other marine life such as fish, crustaceans, and marine invertebrates, and consist of many identical polyps that have grown together. These dense groups provide protection to shorelines against large waves and storms.

As mentioned, the species faces many threats, which include but are not limited to disease, temperature-induced bleaching, and physical damage from hurricanes. The BRT determined that
Elkhorn coral was not at risk for extinction, but could become so in the foreseeable future because its population sizes were low and the severity of threats was predicted to increase.

The NMFS determined that the petition contained substantial information and established the Atlantic Acropora Biological Review Team (BRT) to review the status of these coral species. The BRT included a diverse group of experts from many different scientific fields, including coral conservationists. The BRT published a status review on March 3, 2005, which summarized the relevant, published literature on these species, comments from the public, and an assessment regarding current conservation efforts.

By concentrating their predation activities at night, Elkhorn coral expend less energy catching large amounts of prey. However, because filter feeding is more energy intensive than relying on zooxanthellae, Elkhorn coral will only resort to this feeding method when water conditions are poor and block out sunlight.

757:. Ocean acidification refers to the growing acidity of marine water caused by the increasing presence of dissolved carbon dioxide, a result of carbon emissions. The skeleton of Elkhorn coral is made of calcium carbonate. Carbon dioxide forms chemical bonds with water and, through chemical reactions, remove carbonate ions that the corals need to make calcium carbonate. With fewer carbonate ions, the coral skeletons are weaker and break easier.

Overall, there are no concrete estimates of current or historical population sizes due to technological limitations.

Even 14 years after being listed as threatened, the Elkhorn coral remains so. This failure is in part due to the time and energy-intensive procedures that were previously required to rehabilitate Elkhorn coral reefs. These procedures needed coral to be grown for months to years in nurseries before

In September 2014, the NMFS published a final rule on the listing status of 65 reef-building coral species. This included a re-evaluation of the status of Elkhorn coral. The coral was kept listed as threatened due to concerns from the public that listing it as endangered might impact the ongoing

In 2012, there was discussion surrounding the status of Elkhorn coral and whether it should be reclassified from threatened to endangered. The reasoning behind this proposed change was the continued population decline since the time of the ESA listing in 2006 as well as evidence of recruitment
665:
Since the 1980s, Elkhorn coral populations have rapidly declined by an estimated 97%. Elkhorn coral was initially recognized as a candidate for ESA listing in June 1991, but was removed from the list of candidates in 1997 for a lack of sufficient evidence in regard to their status and threats.

Most commonly, Elkhorn coral reproduce asexually, their most common type of reproduction. During storms, strong waves, or ship disturbances, fragments of coral break off and are transported to other areas where new colonies can begin. The new colonies are genetically identical to their parent
