Despite their crucial importance for terrestrial ecosystems, most tropical plant species lack extinction risk assessments, limiting our ability to identify conservation priorities. Using a novel approach aligned with IUCN Red List criteria, we conducted a continental-scale preliminary conservation assessment of 22,036 vascular plant species in tropical Africa. Our results underline the high level of extinction risk of the tropical African flora. Thirty-three percent of the species are potentially threatened with extinction, and another third of species are likely rare, potentially becoming threatened in the near future. Four regions are highlighted with a high proportion (>40%) of potentially threatened species: Ethiopia, West Africa, central Tanzania, and southern Democratic Republic of the Congo. Our approach represents a first step toward data-driven conservation assessments applicable at continental scales providing crucial information for sustainable economic development prioritization. specialized AFRIQUE ZONE TROPICALE SIERRA LEONE GAMBIE ETHIOPIE LIBERIA SENEGAL COTE D'IVOIRE GUINEE GHANA BENIN OUGANDA 076 082 5 11 eaax9444 [13 p.] 2019 2375-2548 https://www.documentation.ird.fr/hor/fdi:010077420 10.1126/sciadv.aax9444 2375-2548 [F B010077420] https://www.documentation.ird.fr/hor/fdi:010077420 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/divers19-12/010077420.pdf IRD - Base Horizon / Pleins textes 2020-01-07 2025-02-24 fdi:010077420 fre
