The Convention on Migratory Species (CMS) provides an unparalleled opportunity to develop strategies at the international level and foster cooperation between countries to tackle the impacts of climate change on specific species. As climatic changes become more apparent, and the rate of change potentially increases, habitats and species ranges will shift significantly, often crossing national borders in the process. The current protected area network may not match critical sites in future as it does today. Development of an international framework through which countries can cooperate to protect species is an essential step under such dynamic and changing conditions and one in which CMS and its multiple agreements can play a key role.
