A new framework aims to measure the recovery status of species and the impact of conservation actions. Starting with an objective, practical, and ambitious definition of a fully recovered species, the framework proposes 4 conservation metrics to quantify the impact of past and future conservation measures. This framework was recently approved as a new global standard.

The IUCN Standard
