Assessment Information [top]

Red List Category & Criteria: Vulnerable A4ce ver 3.1
Year Published: 2008
Date Assessed: 2008-01-01
Assessor(s): Aronson, R., Bruckner, A., Moore, J., Precht, B. & E. Weil
Reviewer(s): Livingstone, S., Polidoro, B. & Smith, J. (Global Marine Species Assessment)
Justification:
This species is widespread and uncommon throughout its range. However, it is susceptible to bleaching, disease, and extensive reduction of coral reef habitat due to a combination of threats. It has low juvenile survivorship. Specific population trends are unknown but population reduction can be inferred from declines in habitat quality based on the combined estimates of both destroyed reefs and reefs at the critical stage of degradation within its range (Wilkinson 2004). Its threat susceptibility increases the likelihood of being lost within one generation in the future from reefs at a critical stage. Therefore, the estimated habitat degradation and loss of 38% over three generation lengths (30 years) is the best inference of population reduction and meets the threshold for Vulnerable under Criterion A4ce. It will be important to reassess this species in 10 years time because of predicted threats from climate change and ocean acidification.

Population [top]

Population:This species is uncommon but conspicuous. Usually at low abundances, but can be locally abundant in shallower well-circulated areas due to propagation by fragmentation.

There is no species specific population information available for this species. However, there is evidence that overall coral reef habitat has declined, and this is used as a proxy for population decline for this species. This species is particularly susceptible to bleaching, disease, and other threats and therefore population decline is based on both the percentage of destroyed reefs and critical reefs that are likely to be destroyed within 20 years (Wilkinson 2004). We assume that most, if not all, mature individuals will be removed from a destroyed reef and that on average, the number of individuals on reefs are equal across its range and proportional to the percentage destroyed reefs. Reef losses throughout the species' range have been estimated over three generations, two in the past and one projected into the future.

The age of first maturity of most reef building corals is typically three to eight years (Wallace 1999) and therefore we assume that average age of mature individuals is greater than eight years. Furthermore, based on average sizes and growth rates, we assume that average generation length is 10 years, unless otherwise stated. Total longevity is not known, but likely to be more than ten years. Therefore any population decline rates for the Red List assessment are measured over at least 30 years. See the supplementary material for further details on population decline and generation length estimates.

Habitat and Ecology [top]

Habitat and Ecology:Colonies are found on flat or gently sloping back reef and fore reef environments from 1-25 m depth, most commonly from 5-15 m (Goreau and Wells, 1967; E. Weil and A. Bruckner pers. comm.). Colonies do not occur in extremely exposed locations. This colony is resistant to heavy wave surge; however, colonies will occasionally topple due to bioerosion at the bases. Upper portions of the colonies generally survive, and the colony produces multiple new pillars which continue to grow upward (A. Bruckner pers. comm.).
Systems:Marine

Threats [top]

Major Threat(s): This species is highly susceptible to disease (white plague), which has resulted in partial mortality to individual colonies (Bruckner and Bruckner 1997,Weil 2005). Localized impacts have been associated with hurricane damage (e.g., Rogers et al. 1991), other diseases, predation by damselfish, bioerosion by sponges. Collection for curios was reported to be a threat in the past (Colin, 1978), but this has now been banned (A. Bruckner pers. comm.).

Although it propagates through fragmentation, due to reproductive pattern (gonochoric), low juvenile survivorship, and the frequent occurrence of individual clones in localized areas this species may be slow to recover after disturbance events.

In general, the major threat to corals is global climate change, in particular, temperature extremes leading to bleaching and increased susceptibility to disease, increased severity of ENSO events and storms, and ocean acidification.

Coral disease has emerged as a serious threat to coral reefs worldwide and a major cause of reef deterioration (Weil et al. 2006). The numbers of diseases and coral species affected, as well as the distribution of diseases have all increased dramatically within the last decade (Porter et al. 2001, Green and Bruckner 2000, Sutherland et al. 2004, Weil 2004). Coral disease epizootics have resulted in significant losses of coral cover and were implicated in the dramatic decline of acroporids in the Florida Keys (Aronson and Precht 2001, Porter et al. 2001, Patterson et al. 2002). Escalating anthropogenic stressors combined with the threats associated with global climate change of increases in coral disease, frequency and duration of coral bleaching and ocean acidification place coral reefs at high risk of collapse.

Localized threats to corals include fisheries, human development (industry, settlement, tourism, and transportation), changes in native species dynamics (competitors, predators, pathogens and parasites), invasive species (competitors, predators, pathogens and parasites), dynamite fishing, chemical fishing, pollution from agriculture and industry, domestic pollution, sedimentation, and human recreation and tourism activities.

The severity of these combined threats to the global population of each individual species is not known.

Conservation Actions [top]

Conservation Actions: In the US, it is present in many MPAs, including Florida Keys National Marine Sanctuary, Biscayne N.P., and Buck Island Reef National Monument. Also present in Hol Chan Marine Reserve (Belize), Exuma Cays Land and Sea Park (Bahamas). In US waters, it is illegal to harvest corals for commercial purposes. (Aronson, R., Precht, W., Moore, J., Weil, E., and Bruckner, A. pers. comm.)

All corals are listed on CITES Appendix II.

Recommended measures for conserving this species include research in taxonomy, population, abundance and trends, ecology and habitat status, threats and resilience to threats, restoration action; identification, establishment and management of new protected areas; expansion of protected areas; recovery management; and disease, pathogen and parasite management. Artificial propagation and techniques such as cryo-preservation of gametes may become important for conserving coral biodiversity.
