Using multiple International Union for Conservation of Nature (IUCN) Red List criteria to evaluate extinction risks and millions of herbarium and forest inventory records, we present automated conservation assessments for all tree species of the Atlantic Forest biodiversity hotspot, including average 1100 heretofore unassessed species. About 65% of all species and 82% of endemic species are classified as threatened. We rediscovered five species classified as Extinct on the IUCN Red List and identified 13 endemics as possibly extinct. Uncertainties in species information had little influence on the assessments, but using fewer Red List criteria severely underestimated threat levels. We suggest that the conservation status of tropical forests worldwide is worse than previously reported. specialized BRESIL PARAGUAY ARGENTINE AMAZONIE 082ECOSYS 082VEGET 021ENVECO 383 6679 219-225 2024 0036-8075 https://www.documentation.ird.fr/hor/fdi:010090947 10.1126/science.abq5099 0036-8075 [F B010090947] https://www.documentation.ird.fr/hor/fdi:010090947 https://www.documentation.ird.fr/intranet/publi/2024-07/010090947.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2024-06-03 2025-11-06 fdi:010090947 fre
