Two-thirds of biological conservation actions improve biodiversity or slow its decline, a meta-analysis claims.

One in five species included in the list of the Convention on the Conservation of Migratory Species of Wild Animals (CMS, to which Spain is a party) is in danger of extinction. These are data from the first global monitoring report on these species published by the World Conservation Monitoring Centre, a branch of the United Nations Environment Programme (UNEP). This figure rises to 97% for fish species. The authors warn that the situation has deteriorated in recent decades due to "intense levels of anthropogenic pressure". The presentation of the report coincides with the start of the COP on the conservation of these species in Uzbekistan (COP14).
