The Environmental Trust has given the green light for the second stage of the SURG estuarine project, Community action blueprint to enhance estuarine habitat resilience.

 This year marks 25 years since the area surrounding the Solitary Islands was first gazetted as a Marine Reserve, to later become known as the Solitary Islands Marine Park (SIMP).

With all the talk of coral bleaching on the Great Barrier Reef and, closer to home, in the Solitary Islands, it is good to know that some corals are healthy and seem to be thriving among their bleached relatives.

SURG members are currently undertaking emergency surveys to assess the worst coral bleaching ever seen off the Coffs Coast. Water temperatures as high as 27.5 degrees were registered at South Solitary Marine Park in March, causing widespread bleaching on corals growing as deep as 20m. 

SURG members and local dive operators have witnessed severe bleaching in the Solitary Islands, in particular the Pocillopora variety of coral.
