|Scientific Name:||Cantharellus noumeae|
|Species Authority:||Hoeksema & Best, 1984|
|Red List Category & Criteria:||Endangered B2ab(iii) ver 3.1|
|Assessor(s):||Hoeksema, B., Wood, E., Rogers, A. & Quibilan, M.|
|Reviewer(s):||Livingstone, S., Polidoro, B. & Smith, J. (Global Marine Species Assessment)|
This species is endemic to New Caledonia with a restricted range size, and is naturally rare. Threats include habitat degradation due to mining and associated activities and urbanisation. The AOO is calculated as approximately 225 km2. Therefore this species is listed as Endangered under B criterion with less than 5 locations and decline in habitat quality.
|Range Description:||This species is found in New Caledonia. It is also reported from Papua New Guinea, Milne Bay Provence (Allan et al. 2003) but it is unconfirmed and not included in the current distribution.
There are Miocene fossil records form the species from Indonesia (Hoeksema 1989).
Native:Australia; Indonesia; New Caledonia; Papua New Guinea
|FAO Marine Fishing Areas:||
Indian Ocean – eastern; Pacific – western central
|Estimated area of occupancy (AOO) - km2:||225|
|Lower depth limit (metres):||30|
|Upper depth limit (metres):||20|

|Population:||This is a rare species and has a restricted range, endemic to New Caledonia.
There is no species specific population information available for this species. However, there is evidence that overall coral reef habitat has declined.
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 generation length estimates.
|Current Population Trend:||Unknown|
|Habitat and Ecology:||This species is found in deep water close to sediment in sheltered bays. The maximum size is 7cm diameter. It is an attached stalked species (Hoeksema and Best 1984). This species is found from 10-20 m.|
|Generation Length (years):||7|
The main threat to this species is mining activities causing sedimentation and habitat degradation.
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). 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 GBR 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.
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.
Recommended conservation measures include specific localised habitat protection and awareness raising in the region.
All corals are listed on CITES Appendix II. Parts of the species’ range fall within Marine Protected Areas.
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.
