Thirty-four elasmobranch species are listed under the Convention on Migratory Species (CMS). For Appendix II-listed species, CMS Parties have committed to work internationally toward conservation. Appendix I species are to be strictly protected. A CMS Memorandum of Understanding (MoU) for sharks aims to facilitate conservation of listed species. Using Parties’ National Reports and other documentation of existing conservation measures, we examined CMS Parties’ performance with respect to commitments for listed elasmobranch species for which they are considered Range States.
