G As of October 2019, the qualifier DP has been replaced with three new qualifiers to better describe the knowledge gaps that affect assessments, but this change happened after the assessment this row refers to. Given the additional information gathered for this study, none of the DP qualifiers is suggested for the newly circumscribed taxa.表6. 矮生勿忘草（Myosotis，勿忘草属）类群的建议威胁等级分类，以及用于确定该分类的相关数据。 新界定的物种及亚种： 南极勿忘草原亚种（Myosotis antarctica Hook.f. subsp. antarctica）、南极勿忘草特雷尔亚种（Myosotis antarctica subsp. traillii Kirk）、短叶勿忘草（Myosotis brevis de Lange & Barkla）、灰叶勿忘草（Myosotis glauca (G.Simpson & J.S.Thomson) de Lange & Barkla） 种群平均规模：4050（北岛）；1000（南岛）；500（整体）；70 种群规模区间：6~150；5~200；50~2000；5~2000 种群数量：20；13；10；5 估计现存种群总数：29；95；83；538 基于种群平均规模×种群数量计算的估计总普查种群规模：12006；2875；17600；4601 被认为已灭绝的种群数量：2；1；1；1 种群趋势：稳定；下降10%~20%；波动（Rogers等，2002）；稳定 占用面积（AOO）：1.69 km²（注B）；0.35 km²（注B）；0.25 km²（注B）；0.17 km²（注B） de Lange等（2018）中的原威胁等级： 原以M. drucei之名：无威胁；原以南极勿忘草之名：处于风险：自然稀见（DP, G, Sp, TO）；原以矮生勿忘草之名：处于风险：下降（Sp）；受威胁：全国易危（EF, Sp）；受威胁：全国易危（DP, G, Sp） 建议威胁等级：处于风险：自然稀见；受威胁：全国易危；受威胁：全国易危；受威胁：全国易危 建议限定词：Sp, TO；Sp；EF, Sp；RR, Sp 基于Townsend等（2008）的标准确定建议威胁等级的依据： 1. 种群稳定；估计成熟个体总数为5000~20000 2. 等级标准：C(1)成熟个体1000~5000，且C(3)占用面积<100公顷（1 km²）；种群趋势：预计下降10%~50% 3. 等级标准：C(3)占用面积<100公顷（1 km²）；种群趋势：预计下降10%~50% 4. 等级标准：B(1)成熟个体1000~5000，且B(3)占用面积<100公顷（1 km²）；种群趋势：种群稳定 分布在新西兰保育部（Department of Conservation, DOC）管理土地上的种群占比（详见补充表S1）：72%；26%；24%；31% ### 注释 注：DP：数据匮乏；EF：极端波动；RR：分布区受限；Sp：种群稀疏；TO：境外受威胁（新西兰威胁分类系统NZTCS；详见Rolfe等，2021） 注A：基于2011-2015年调查的种群；详见Prebble等，2019的表2 注B：基于AK、CHR、OTA和WELT馆藏标本确定的种群分布点数量计算所得 注C：坎贝尔岛，温德拉什湾；北岛南部，马塔莫 注D：北岛南部：怀拉拉帕，卡斯尔角；塔拉纳基：普克塔普路；纳尔逊韦斯顿：沃拉里基海滩 注E：吉斯伯恩：东角 注F：坎特伯雷：奥豪湖 注G：截至2019年10月，限定词DP已被三个新限定词取代，以更好地描述影响评估的知识空白，但该修订发生在本表所涉评估之后。结合本研究收集的额外信息，本次新界定的类群均不建议使用DP限定词。
