As global attention turns to the 15th Meeting of the Conference of the Parties to the Convention on the Conservation of Migratory Species of Wild Animals (CMS COP15) in Brazil, a new report has warned that 49% of migratory species populations conserved by the global UN treaty are declining, and 24% of species face extinction. The statistics are revealed in the review of the State of the World’s Migratory Species Report to be presented to COP15 this week. It has drawn the attention of Pacific delegates, who are in Campo Grande, Brazil, for one of the most important global meetings for wildlife conservation.
