极危 (Critically Endangered, CR): 种群面临高度灭绝风险，符合CR标准中的A-E任一条件。濒危 (Endangered, EN): 种群未来面临较高灭绝风险，但未达到CR标准，符合EN标准。易危 (Vulnerable, VU): 种群虽未达到CR或EN，但未来一段时间内可能存在较高灭绝风险，符合VU标准。近危 (Near Threatened, NT...

IUCN Red List根据物种的种群数量、分布范围、种群结构、生境质量等多个因素,将物种划分为不同的濒危等级。主要的濒危等级包括灭绝(Extinct, EX)、野外灭绝(Extinct in the Wild, EW)、极危(Critically Endangered, CR)、濒危(Endangered, EN)、易危(Vulnerable, VU)、近危(Near Threate...

这些分类包括无危（Least Concern, LC）、近危（Near Threatened, NT）、易危（Vulnerable, VU）、濒危（Endangered, EN）和极度濒危（Critically Endangered, CR）。基于A2–4标准，"可能状态"的确定是基于包含最高后验概率的分类，但有一个例外，即当LC获得最高概率但概率小于50%时，VU也会被选择。所有的概率...
