From Surviving to Thriving: Inside the IUCN Green Status of Species

In this episode Elizabeth Bock speaks with Dr Molly Grace (University of Oxford), co-chair of the IUCN Green Status of Species working group. The conversation explains how the Green Status complements the Red List by measuring species recovery, not just extinction risk. Molly unpacks the three components of recovery (distribution, viability, functionality), explains how the assessment quantifies the impact of conservation actions, and outlines how the Green Status can be used for national reporting under the Global Biodiversity Framework.

Key takeaways

• The Green Status answers a question the Red List does not: what does recovery look like, and how much has conservation achieved so far.
• Recovery is measured using three components: distribution (pre-impact vs current range), viability (extinction risk), and functionality (ability to perform ecological roles).
• The assessment includes a counterfactual element: it estimates what recovery would look like without past conservation, making conservation impact visible.
• Baselines matter and are contested; the Green Status uses a pre-impact baseline within the past 500 years to allow standardised comparison.
• Early priorities include improving taxonomic coverage (beyond charismatic vertebrates) and piloting national reporting with countries such as Indonesia and South Africa.
