The first Report on the Status of Migratory Species showed that populations of most migratory species covered by the CMS are declining and that biological resource use is a significant threat to the listed species. It was agreed that a more comprehensive review should be undertaken to better understand the status of individual species and the main threats.

The Secretariat will initiate an in-depth review of the conservation status of individual CMS-listed species, starting with those species listed in Appendix I, and will carry out an assessment of the impact of direct use on the conservation status of these species. Special consideration will be given to taking species from nature for international trade.
