Full description The Marine chapter of the 2021 State of the Environment (SoE) report incorporates multiple expert templates developed from streams of marine data. This metadata record describes the Expert Assessment "State and Trend of shallow rocky reefs (<30m)".
***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 - Shallow rocky reefs (<30m)"***
----------------------------------------
DESCRIPTION OF HABITAT/COMMUNITY/PROCESS FOR EXPERT ASSESSMENT
Assemblages of plants and animals found on inshore shallow rocky reefs <30 m depth in the temperate zone. The primary focus here is on habitats and mobile invertebrates while fishes are covered in other assessments.
DATA STREAM(S) USED IN EXPERT ASSESSMENT
Underwater visual census data from, Australian Temperate Reef Collaboration (ATRC; https://atrc.org.au/), Parks Victoria subtidal monitoring program and the Reef Life Survey program (RLS; https://reeflifesurvey.com/). Data collected between the years 2008-2020 (inclusive) were reported in the Australia’s changing reefs case study, with data from Jurien Bay, Rottnest Island (WA), Encounter (SA), Port Phillip, Beware Reef and (Vic), Kent Group, SE Tasmania, Maria Island (Tas), Batemans Bay, Jervis Bay, Sydney, and Port Stephens (NSW) the key locations with time series data.
