“The coral bleaching event that is wreaking havoc in the northern part of the Great Barrier Reef is also being expressed along the subtropical coast of eastern Australia. Preliminary work being conducted in the Solitary Islands near Coffs Harbour in northern New South Wales, led by myself and the ARC Centre of Excellence for Coral Reef Studies, shows widespread coral bleaching with a number of coral genera feeling the heat.  The hardest hit corals appear to be the pocilloporids, (Pocillopora in particular, but also Stylophora), and the genus Turbinaria. However, other taxa, such as Porites are also showing substantial bleaching.

Of particular concern is that in many places around the Solitary Islands, the two hardest hit corals are two of the most abundant.  Moreover, some of the Pocillopora colonies are dying or have already died.  Should mortality ensue for these two dominant corals on the reef, Australia’s subtropical reefs could undergo major changes in their biotic composition.  On the positive side, many of the hardest hit corals on the Great Barrier Reef, such as Acropora, are showing only minimal stress to the sub-tropical bleaching event.”
