This species is listed as Endangered as the species is believed to have undergone a decline exceeding 50% over the past 30 years due in particular to the effects of disease and bleaching, as well as other factors. Current rates of mortality are exceeding growth and recruitment, and current threats are increasing and spreading into new areas. Due to their extreme longevity, low rates of recruitment and long generation times, scope for recovery of populations is limited. If current trends continue, this species may warrant listing in a higher category of threat.
