“…Diary Bull reef has for several years been the fringing reef around Discovery Bay, Jamaica, with high rugosity, the most coral cover, with a benthic community similar to that of the 1970s (Huston, 1985), and it was the subject of the study which suggested a rapid phase-shift reversal (Idjadi et al, 2006 Quinn and Kojis (2008). It is encouraging that coral cover and the rapidly growing A. cervicornis colonies have returned to the reef at levels approaching pre-bleaching values.…”

After the 2005 bleaching event there was a major loss of live coral cover, particularly of A. cervicornis (Quinn & Kojis, 2008). Here, we investigate coral cover at Dairy Bull reef over a ten year period, from 2002-2012.…”

Current challenges to coral reef sustainability include overfishing, destructive fishing practices, bleaching, acidification, sea-level rise, starfish, algae, agricultural run-off, coastal and resort development, pollution, diseases, invasive species and hurricanes. We used SCUBA belt transects to record coral cover and digital image analysis in the Dairy Bull Reef off the north coast of Jamaica and found that it is a positive example of how reefs can recover after major environmental disturbance.

“…After the 2005 bleaching event there was a major loss of live coral cover [32,33], and it is encouraging that the population size studies show that there are numbers of both small and large colonies at both Discovery Bay and Port Royal sites. Also, the linear extension rates of A. palmata branching corals at Dairy Bull, Rio Bueno, and Pear Tree Bottom on the north coast of Jamaica were maintained from 2005-2012.…”

Knowledge of factors that are important in coral reef growth help us to understand how reef ecosystems react following major environmental disturbances due to climate change and other anthropogenic effects. This study shows that despite a range of anthropogenic stressors, corals on the fringing reefs south of Kingston harbour, as well as corals on fringing reefs on the north coast of Jamaica near Discovery Bay can survive and grow. Skewness values for Sidastrea siderea and Porites astreoides were positive (0.85 -1.64) for all sites, implying more small colonies than large colonies. Coral growth rates are part of a demographic approach to monitoring coral reef health in times of climate change, and linear extension rates (mm·yr The range of small-scale rugosities at the Port Royal cay sites studied was lower than that at the Discovery Bay sites; for example Rio Bueno was 1.05 ± 0.15 and Dairy Bull the most rugose at 2.3 ± 0.16. Diary Bull reef has for several years been the fringing reef with the most coral cover, with a benthic community similar to that of the 1970s. We discuss whether Jamaica can learn from methods used in other Caribbean countries to better protect its coral reefs against climate change. Establishing and maintaining fully-protected marine parks in Jamaica and elsewhere in the Caribbean is one tool to help the future of the fishing industry in developing countries. Developing MPAs as part of an overall climate change policy for a country may be the best way of integrating climate change into MPA planning, management, and evaluation.

“…Increases in the density of the grazing sea urchin Diadema antillarum, following its epidemic die-off in the 1980s, have been associated with greater coral recruitment in Jamaica [111,112]. Aer mortality from bleaching in 2005 reversed some of these gains [104,113], coral cover is once again increasing [104].…”

Irrefutable evidence of coral reef degradation worldwide and increasing pressure from rising seawater temperatures and ocean acidification associated with climate change have led to a focus on reef resilience and a call to “manage” coral reefs for resilience. Ideally, global action to reduce emission of carbon dioxide and other greenhouse gases will be accompanied by local action. Effective management requires reduction of local stressors, identification of the characteristics of resilient reefs, and design of marine protected area networks that include potentially resilient reefs. Future research is needed on how stressors interact, on how climate change will affect corals, fish, and other reef organisms as well as overall biodiversity, and on basic ecological processes such as connectivity. Not all reef species and reefs will respond similarly to local and global stressors. Because reef-building corals and other organisms have some potential to adapt to environmental changes, coral reefs will likely persist in spite of the unprecedented combination of stressors currently affecting them. The biodiversity of coral reefs is the basis for their remarkable beauty and for the benefits they provide to society. The extraordinary complexity of these ecosystems makes it both more difficult to predict their future and more likely they will have a future.
