This record provides an overview of the NESP Marine and Coastal Hub bridging study - "A photo-identification study of southern right whales to update aggregation area classification in the southwest of Australia". For specific data outputs from this project, please see child records associated with this metadata.<br /> --------------------<br /> <br /> Aerial surveys of southern right whales (Eubalaena australis) have been conducted across the southern Australian coast from Perth (W.A.) to Ceduna (S.A.) since 1993, as part of a long-term program to monitor the recovery, and inform the Conservation Management Plan (2011-2021), for this Endangered species (under the EPBC Act). The 2020 aerial survey recorded substantially lower numbers of whales than in the previous 13 years, and the lowest number of non-calving whales since the program started. An aerial survey conducted by this project in August 2021 will provide a relative estimate of annual population size for determining longer term population trends and contribute to determining if 2020 was an anomalous year or an indicator of some longer-term change to recent recovery rates and the female breeding cycle.<br /> <br /> Outputs<br /> • Aerial whale survey data (counts by size class, number, and location) - 2021-22 season [dataset]<br /> • Individual whale photo-identification data - 2021-22 season [imagery - published to ARWPIC]<br /> • Final technical report with analysed data, including a short summary of recommendations for policy makers of key findings [written]
