A new analysis of biodiversity and conservation knowledge products to support environmental assessments

The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) second global assessment of the state of biodiversity is in preparation, to be completed in 2028. To support this and other global and regional environmental assessments, we disaggregate three global knowledge products based on IUCN standards (the IUCN Red List of Threatened Species, Key Biodiversity Areas and Protected Planet), by IPBES regions and subregions, units of analysis and direct drivers. We present twenty-one data tables organised in seven thematic data groups: i) threatened species; ii) endemic and exclusive species; iii) trends in downscaled Red List Indices; iv) threat abatement potential (STAR-T); v) restoration potential (STAR-R); vi) protected and conserved area coverage (and effectiveness); and vii) key biodiversity area numbers and protected area coverage. We also present three novel crosswalks from IUCN countries, habitats and threats to IPBES regions, units of analysis and direct drivers, respectively. These data can readily be used to inform global, regional and subregional assessments of the status of biodiversity and drivers of its change.
