Rocky reefs are a common feature of Kangaroo Island’s coastline. They range from huge, smooth granite slabs to intricate, highly dissected limestone reefs that are full of nooks and crannies. These reefs are home to an incredible array of plants and animals that are integral to the health of our Island.

Common critters to be found on our reefs include: Blue groper, harlequin fish, snapper, rock lobsters, leafy seadragons, abalone, seastars and seals. Some of these species have disappeared or are becoming rare in other parts of South Australia.

Over the last 2 years the Coast and Marine Program, with the help of trained local divers, has surveyed 22 sites along the north coast of Kangaroo Island to assess the health of our reefs. This is done by swimming along a 50-metre underwater transect counting fish and large invertebrates.

So far we have recorded over 160 species and counted more than 30,000 animals!  The Coast and Marine Program will continue to monitor these reefs in the future.
