***A PDF of the full Expert Assessment, including figures and tables (where provided) is downloadable in the "On-line Resources" section of this record as "EXPERT ASSESSMENT 2021 - Oceanic reefs"***

----------------------------------------

DESCRIPTION OF HABITAT/COMMUNITY/PROCESS FOR EXPERT ASSESSMENT
Assemblages of plants and animals found on shallow offshore reefs in the 0-30 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, based on results from the national case study ‘Australia’s changing reefs’.

DATA STREAM(S) USED IN EXPERT ASSESSMENT
Underwater visual census data from Reef Life Survey, as reported in references. NW and Elizabeth & Middleton reefs surveyed in 2013 and 2018, Lord Howe Island 2006, 2008, 2009, 2010, 2012, 2014, 2016, 2018 and 2020. Coral Sea 2012, 2013, 2016, 2017, 2018, 2019 (2020 data not yet available for assessment), Norfolk Island (2009, 2013).
While results were based on those regions covered in the national case study ‘Australia’s changing reefs’ in which quantitative comparisons were made with standardised data, other relevant monitoring data have been collected by the Australian Institute of Marine Science, James Cook University, CSIRO and the Sydney Institute of Marine Science. It is uncertain whether trends reported here are consistent with those indicated by those other monitoring programs.
