Higher ocean acidity contributes to bleaching and also reduces the ability of corals and other marine animals to build hard shells. The decline in coral cover in caribbean reefs over time. Even though staghorn coral is the fastest growing species of all corals growing in western Atlantic waters, it has been listed as federally threatened under the Endangered Species Act. This turbidity increase can result from a myriad of issues like untreated wastewater and beach erosion activities. These provide important habitat for other reef animals, especially fish. These resistant staghorn coral genotypes may explain why pockets of Acropora have been able to survive the WBD epidemic. The growth pattern is similar in appearance to antlers of elk.  Often, Elkhorn coral will have a yellow to yellowish-brown coloration due to the presence of a symbiotic zooanthellae which lives within the cells of the coral animal.

The species was listed as threatened under the U.S. Why are elkhorn and staghorn coral now listed as threatened under the Endangered Species Act? The coral receives nutrients and oxygen from algae, and the algae receive nutrients and carbon dioxide from the coral. These resistant staghorn coral genotypes may explain why pockets of Acropora have been able … Animal Research Medical Monitoring Program. Elkhorn corals have a relatively more massive structure than Staghorn corals but are also susceptible to the same threats. Staghorn corals derive their name from their appearance which is reminiscent of the multiple pointed antlers of male deer, or stag. Staghorn coral 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. They cover less than 1% of the ocean floor but are habitat for at least 25% of all known marine life. Acropora is a relatively fast growing coral (2-4 inches annually) but is highly susceptible to damage caused by storm and surge activity. Unfortunately, the conservation status of the Staghorn coral, according to the IUCN, is worse than endangered. Purpose: The purpose of these data is to visually represent the critical habitat areas for GIS analysis and display. Predict: In the Caribbean, water temperatures … 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 threate… Populations of staghorn coral have been collapsing throughout their range, and the species has been locally extirpated in some … White band disease was discovered when biologists observed the peeling of tissue from colonies of elkhorn and staghorn (Acropora spp.) The Great Barrier Reef contains around 600 species of coral, consisting of both hard corals and soft corals. Why do you think corals have declined since 1977? It, along with staghorn coral and star corals (boulder, lobed, and mountainous), built Caribbean coral reefs over the last 5,000 years.

These resistant staghorn coral genotypes may explain why pockets of Acropora have been able to survive the WBD epidemic. For example, in our coral tree nurseries, we grow elkhorn, staghorn and other corals and are able to outplant them back onto degraded reefs. The greatest threat to staghorn coral is ocean warming, which cause the corals to release the algae that lives in their tissue and provides them food, usually causing death. What does it … But the progress is slowed by increased populations of urchins and other creatures that hinder growth.

Most Acropora reefs have now been reduced to barren rubble fields with a corresponding loss in habitat for other species. The numerous interlaced branching growth patterns of Acropora historically formed large reef structures which protected the high energy ocean side or "front" of reef zones and provided critical habitat for fish and invertebrates. 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 … The affected areas adjacent to the dredge site are of high conservation value and have been designated as “critical habitat” for the recovery of these threatened staghorn corals.
