The Marine chapter of the 2016 State of the Environment (SoE) report incorporates multiple expert templates developed from
streams of marine data. This metadata record describes the Expert Assessment "The state and trends of ecological communities/habitats
– offshore banks, shoals, islands". The full Expert Assessment, including figures and tables (where provided), is attached
to this record. Where available, the Data Stream(s) used to generate this Expert Assessment are accessible through the "On-line
Resources" section of this record.
DESCRIPTION OF ECOLOGICAL HABITAT/COMMUNITY FOR EXPERT ASSESSMENT
Assemblages of plants and animals found on offshore banks, and shoals around islands, in the 0-25 m depth range. This largely
relates to reefs in the Coral Sea, Elizabeth and Middleton Reefs, Lord Howe Island, Norfolk Island, and the offshore reefs
in the north and north-west.
DATA STREAM(S) USED IN EXPERT ASSESSMENT
Reef Life Survey data were used for the current status assessment, with extensive spatial coverage of sites on most offshore
banks, shoals and Island around the continent where the seabed rises to within 20 m of the surface.
