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 dolphins and porpoises". <br /> ***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 - Dolphins and Porpoises"***<br /> <br /> ----------------------------------------<br /> <br /> DESCRIPTION OF TAXONOMIC GROUP FOR EXPERT ASSESSMENT<br /> Following taxonomic standards, 20 dolphin species in the Family Delphinidae and one species in the Family Phocoenidae are known to occur in Australian waters (Table 1). A number of these species (e.g. common dolphins, Delphinus delphis) are distributed nationally, others are restricted to particular latitudes (e.g. dusky dolphin, Lagenorhychus obscurus) and others consist of populations that are highly restricted to embayments and tributaries within particular regions (e.g. the endemic Australian snubfin dolphin, Orcaella heinsohni). <br /> Since the 2016 State of the Environment (SoE) report further insights into the spatial distribution of Australian snubfin dolphin (Blue Planet Marine 2019, Bouchet et al. 2021), Australian humpback dolphins (Sousa sahulensis; Parra and Cagnazzi 2015, Hanf et al. 2016, Hunt et al. 2017; Raudino et al. 2018a, Raudino et al. 2018b, Blue Planet Marine 2019, Burns et al. 2019, Hunt et al. 2020), Indo-Pacific bottlenose dolphins (Tursiops aduncus, Raudino et al. 2018a, Blue Planet Marine 2019, Burns et al. 2019, Haughey et al. 2020), common dolphins (Delphinus delphis, Mason et al. 2016) and orca (Orcinus orca, Jones et al. 2019, Salgado-Kent et al. 2020) have been established. <br /> <br /> DATA STREAM(S) USED IN EXPERT ASSESSMENT<br /> Assessment based on review of literature published since the 2016 SoE assessment – see references for spatial and temporal coverage of data incorporated into assessments. <br /> <br /> ----------------------------------------<br /> <br /> 2021 SOE ASSESSMENT SUMMARY [see attached Expert Assessment for full details]<br /> <br /> • 2021 •<br /> Assessment grade: Good<br /> Assessment trend: Unclear<br /> Confidence grade: Limited evidence or limited consensus<br /> Confidence trend: Limited evidence or limited consensus<br /> Comparability: Grade and trend are comparable to the 2016 assessment<br /> • 2016 •<br /> Assessment grade: Good<br /> Assessment trend: Unclear<br /> Confidence grade: Limited evidence or limited consensus<br /> Confidence trend: Limited evidence or limited consensus<br /> Comparability: Grade and trend are somewhat comparable to the 2011 assessment<br /> • 2011 •<br /> Assessment grade: Good<br /> Assessment trend: Stable<br /> Confidence grade: Limited evidence or limited consensus<br /> Confidence trend: Limited evidence or limited consensus<br /> <br /> ----------------------------------------<br /> <br /> CHANGES SINCE 2016 SOE ASSESSMENT<br /> Assessment has not changed.

《2021年环境状况报告》的海洋章节包含了从海洋数据流中开发的多个专家模板。此元数据记录描述了专家评估“海豚和鼠海豚的状态和趋势”。<br /> * 专家评估报告全文的PDF格式，包括图表（如有提供），可在本记录的“在线资源”部分下载，名称为“专家评估2021 -海豚和鼠海豚”*<br /> <br /> ----------------------------------------<br /> <br /> 专家评估分类组的描述<br /> 根据分类标准，已知在澳大利亚沃茨有20种海豚科和1种海豚科。其中一些物种（如普通海豚，Delphinus delphis）分布在全国各地，其他物种仅限于特定纬度（如dusky dolphin，Lagerichychus obscurus），其他物种的种群高度局限于特定区域内的海湾和支流（如澳大利亚特有的snubfin dolphin，Orcaella heinsohni）。 <br /> 自2016年环境状况（SoE）报告以来，进一步深入了解了澳大利亚snubfin海豚的空间分布（Blue Planet Marine 2019，Bouchet et al. 2021），澳大利亚驼背海豚（Sousa sahulensis; Parra和Cagnazzi 2015，Hanf等人2016，Hunt等人2017; Raudino et al. 2018 a，Raudino et al. 2018 b，Blue Planet Marine 2019，Burns et al. 2019，Hunt et al. 2020），印度太平洋短吻海豚（Tursiops aduncus，Raudino等人，2018 a，Blue Planet Marine 2019，Burns等人，2019，Haughey等人，2020），普通海豚（Delphinus delphis，Mason et al. 2016）和虎鲸（Orcinus orca，Jones et al. 2019，Salgado-Kent et al. 2020）。<br /> <br /> 用于专家评估的数据流<br /> 评估基于自2016年SoE评估以来发表的文献综述-评估中纳入的数据的空间和时间覆盖范围见参考文献。<br /> <br /> ----------------------------------------<br /> <br /> 2021年国有企业评估摘要[详细信息请参见随附的专家评估]<br /> <br /> · 2021 ·<br /> 评价等级：良好<br /> 评估趋势：不明确<br /> 置信度：证据有限或共识有限<br /> 可信度趋势：证据有限或共识有限<br /> 可比性：等级和趋势与2016年评估相当<br /> · 2016 ·<br /> 评价等级：良好<br /> 评估趋势：不明确<br /> 置信度：证据有限或共识有限<br /> 可信度趋势：证据有限或共识有限<br /> 可比性：等级和趋势与2011年评估有一定可比性<br /> · 2011 ·<br /> 评价等级：良好<br /> 评估趋势：稳定<br /> 置信度：证据有限或共识有限<br /> 可信度趋势：证据有限或共识有限<br /> <br /> ----------------------------------------<br /> <br /> 2016年以来的变化<br /> 评估没有改变。
