Species Threat Abatement and Restoration Metric (STAR)


STAR stands for “Species Threat Abatement and Restoration”. It is a biodiversity metric based on The IUCN Red List of Threatened Species, which combines data on species, the threats they face and their risk of extinction, to produce two complementary global data layers for threat abatement and restoration opportunity. These can be used by organisations to identify areas where actions to abate threats or undertake restoration can help reduce species extinction risk and contribute to conservation goals 1 2.
