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
– fringing temperate rocky reefs". 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 coastal rocky reefs <25 m depth in the temperate zone, not including reefs within
large marine embayments (covered in the Coasts chapter). As fishes are covered in other assessments, the primary focus here
is on habitat-forming biota and mobile invertebrates.
DATA STREAM(S) USED IN EXPERT ASSESSMENT
Reef Life Survey and Long-term Temperate Reef Monitoring program data were used for the current status assessment, with
extensive spatial coverage of sites around the continent. Temporal trend information came from a combination of RLS and
LTTRMP at six particular locations (MPA locations include the broader region and sites inside and outside sanctuary zones):
NSW: Batemans Marine Park, Jervis Bay Marine Park, Sydney, Port Stephens
VIC: Beware Reef, Port Phillip Heads
SA: Encounter Bay (Fleurieu Peninsula)
WA: Rottnest Island, Jurien Marine Park
TAS: Maria Island

QUALITY OF DATA USED IN THE ASSESSMENT
Data collected using standardised methods.
CUSTODIAN AND LOCATION OF DATA
RLS data are publically available at www.reeflifesurvey.com, custodian for the LTTRMP is Neville Barrett (Neville.Barrett@utas.edu.au).
METHOD USED TO DETERMINE STATE OR RECENT TREND
The analysis is based on species recorded at each site in 3 years or more over last 10 years for monitoring locations, with
abundance of each species standardised by their maximum abundance at that particular site. Mean trend then represents the
mean standardised abundance of species across all sites surveyed in a given year.
