This species is listed as Critically Endangered as there has been a population reduction exceeding 80% over the past 30 years due, in particular to the effects of disease, as well as other climate change and human-related factors. This species is particularly susceptible to bleaching. Although the current population is persisting at a very low abundance and the current population trend appears to be stable, there are places where populations continue to decrease and others where there seems to be moderate or localized recovery. Whether mortality continues to exceed growth and recruitment or not, this species requires immediate investigation and monitoring on a regional scale.
