The Expert Group is requested to: a) progress work on the development of a management tool at a workshop proposed for 2020, with the specific task of testing the tool on the CMS Appendices and identifying priority species and social groups; b) continue further development of case studies so that these can be brought forward at the 2020 workshop to inform this process; c) once key priority species have been established, develop a more comprehensive workplan beyond 2020, which should include: i. Identification of case studies relevant to CMS; ii. Development of robust criteria and a management tool for prioritizing species and social groups on the CMS Appendices; iii. Development of any relevant concerted actions arising from the prioritization process; iv. Identification of key daughter agreements which might benefit from dissemination of this work; d) make recommendations to the Meeting of the Sessional Committee of the Scientific Council preceding the 14th meeting of the Conference of the Parties (COP14).
