Taxonomy [top]

Kingdom Phylum Class Order Family
Animalia Cnidaria Anthozoa Scleractinia Poritidae

Scientific Name: Porites pukoensis
Species Authority: Vaughan, 1907

Assessment Information [top]

Red List Category & Criteria: Critically Endangered D ver 3.1
Year Published: 2008
Date Assessed: 2008-01-01
Assessor(s): Sheppard, A., Fenner, D., Edwards, A., Abrar, M. & Ochavillo, D.
Reviewer(s): Livingstone, S., Polidoro, B. & Smith, J. (Global Marine Species Assessment)
Justification:
This species is known from only one small site in Hawaii. It is very rare with probably fewer than 50 colonies. Extent of occurrence and area of occupancy meet the criterion B thresholds (<100 km² and 10 km² respectively) and it is known from only one location. However, there is no evidence of continuing decline at present, therefore criterion B cannot be used. However, with fewer than 50 colonies the species qualifies for Critically Endangered under Criterion D.

Threats [top]

Major Threat(s): This species has a highly restricted range.

The unbranching species in this genus is not particularly susceptible to bleaching, but is more prone to disease than many other corals.

Coral disease has emerged as a serious threat to coral reefs worldwide and is 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). In the Indo-Pacific, disease is also on the rise with disease outbreaks recently reported from the Great Barrier Reef (Willis et al. 2004), Marshall Islands (Jacobson 2006) and the northwestern Hawaiian Islands (Aeby 2006). Increased coral disease levels on the Great Barrier Reef were correlated with increased ocean temperatures (Willis et al. 2007) supporting the prediction that disease levels will be increasing with higher sea surface temperatures. 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 in the Indo-Pacific at high risk of collapse.

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. In addition to global climate change, corals are also threatened by a number of localized threats. 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: All corals are listed on CITES Appendix II. Parts of this species distribution fall within several Marine Protected Areas within its range.

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.

Having timely access to national-level trade data for CITES analysis reports would be valuable for monitoring trends this species. The species is targeted by collectors for the aquarium trade and fisheries management is required for the species, e.g., Marine Protected Areas, quotas, size limits, etc. Consideration of the suitability of species for aquaria should also be included as part of fisheries management, and population surveys should be carried out to monitor the effects of harvesting.
