IUCN Green Status of Species
The IUCN Green Status of Species is a conservation assessment system published by the International Union for Conservation of Nature (IUCN) that grades the impact of recovery and conservation efforts for individual species. The first version of the Green Status assessment guidelines was published in 2018, and integration of Green statuses into Red List assessments was formalized as an optional component in 2020. The second version of the framework was published in 2021.
