Specific population trends are unknown but population reduction can be inferred from estimated habitat loss (Wilkinson 2004). It is less widespread and common throughout its range and therefore is likely to be more resilient to habitat loss and reef degradation because of an assumed large effective population size that is highly connected and/or stable with enhanced genetic variability. Therefore, the estimated habitat loss of 25% from reefs already destroyed within its range is the best inference of population reduction since it may survive in coral reefs already at the critical stage of degradation (Wilkinson 2004). This inference of population reduction over three generation lengths (30 years) does not meet the threshold of a threat category. However, since this population reduction estimate is close to a threatened threshold, and because this species is moderately susceptible to a number of threats, it is likely to be one of the species lost on some reefs currently at the critical stage of degradation and therefore is Near Threatened. Predicted threats from climate change and ocean acidification make it important to reassess this species in 10 years or sooner, particularly if the species is actually observed to disappear from reefs currently at the critical stage of reef degradation.
