Statement: QUALITY OF DATA USED IN THE ASSESSMENT Data used to determine state and trend are based on systematic surveys for the relevant species. Methods and associated quality of data produced by those surveys are detailed in the publications provided in the reference list. Purpose To describe the state and trends in populations of whales for use in the Marine chapter of the 2016 State of the Environment report. 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 quality of species and groups – whales". 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 TAXONOMIC GROUP FOR EXPERT ASSESSMENT A total of 24 species of whales (two of which comprise two subspecies) have been documented from Australian waters with a further one (Omura’s whale) likely to occur, but yet to be definitively confirmed. A number of these species (e.g. sperm whale) are distributed nationally, others are restricted to particular latitudes (e.g. Bryde’s whale) and others consist of populations that only seasonally utilise Australian waters (e.g. some of the baleen whale species). DATA STREAM(S) USED IN EXPERT ASSESSMENT This assessment is based on peer-review papers and reports provided by a series of researchers working on whales in Australia. Details on the specific data products used in this assessment have not been provided. --- 2016 SOE ASSESSMENT SUMMARY [see attached Expert Assessment for full details] • 2016 • Assessment grade: Good Assessment trend: Unclear Confidence grade: Limited evidence or limited consensus Confidence trend: Limited evidence or limited consensus Comparability: Grade and trend are somewhat comparable to the 2011 assessment • ...
