Plant Species - Threatened

"Threatened" includes species listed as Critically Endangered (CR), Endangered (EN) and Vulnerable (VU). A taxon is Critically Endangered when the best available evidence indicates that it meets any of the criteria A to E for Critically Endangered and it is therefore considered to be facing an extremely high risk of extinction in the wild. A taxon is Endangered when the best available evidence indicates that it meets any of the criteria A to E for Endangered and it is therefore considered to be facing a very high risk of extinction in the wild. A taxon is Vulnerable when the best available evidence indicates that it meets any of the criteria A to E for Vulnerable and it is therefore considered to be facing a high risk of extinction in the wild.“受威胁（Threatened）”物种涵盖被列为极危（Critically Endangered，CR）、濒危（Endangered，EN）以及易危（Vulnerable，VU）的物种。 当现有最佳可用证据表明某一分类单元（taxon）符合极危物种的A至E任意一项判定标准时，该分类单元即被认定为极危物种，面临极高的野外灭绝风险。 当现有最佳可用证据表明某一分类单元符合濒危物种的A至E任意一项判定标准时，该分类单元即被认定为濒危物种，面临甚高的野外灭绝风险。 当现有最佳可用证据表明某一分类单元符合易危物种的A至E任意一项判定标准时，该分类单元即被认定为易危物种，面临较高的野外灭绝风险。
