34% of the waterway’s foreshore has been cleared of native vegetation and now consists of urban and rural land or exotic vegetation. The retained native vegetation elsewhere consists primarily dry eucalypt communities, but also includes areas of:
- saltmarsh and wetland
- wet eucalypt forest and woodland
- non-eucalypt forest and woodland (e.g. she-oak forests)
- scrub, heath and coastal complexes and
- native grassland.
There are few formal records showing how flora and fauna in the intertidal zone has changed. This is something that beachcombers, rock pool enthusiasts, fishers and divers may be able to help us with.
The waterway’s coastline includes 54 wetlands and 43 saltmarshes. The tidal flats at Oyster Cove are listed on the Directory of Important Wetlands in Australia, and the Port Cygnet Conservation Area includes wetland habitat that is significant for the State. The Lutregala Marsh at the southern end of Bruny Island Neck is of particularly high conservation significance due to species-rich invertebrate communities.
Threatened species that may be spotted on the foreshore intertidal zone include:
