Conservation assessments present a formidable challenge for regions of the developing world such as the Lesser Antilles. Of the 2652 seed plant taxa recorded from this archipelago (Acevedo-Rodríguez & Strong, 2012, 2016), only 150 taxa (including 14 endemics) are listed in the IUCN Red List. Using only herbarium data, we carried out a preliminary conservation assessment of the 263 seed plant taxa unique to these islands by two methods. Using the algorithm originally developed to assess the Hawaiian flora (Krupnick et al. in Biodiversity and Conservation 18: 1459–1474, 2009), 8% of the taxa were deemed to be Potentially Extinct and 62% Potentially Threatened while 30% were assessed as Not Threatened. Using a Red List criteria approach, 70% were deemed Threatened (Critically Endangered, Endangered and Vulnerable), while 30% were assessed as Near Threatened, Least Concern or Data Deficient. The congruence between the assessments by these distinct methods and for the 14 Red Listed species validate this approach as a first step in prioritising plant conservation efforts.

基于标本馆的小安的列斯群岛特有种子植物的初步保护评估揭示了处于危险之中的植物群

保护评估对小安的列斯群岛等发展中世界地区提出了艰巨的挑战。在该群岛记录的 2652 种种子植物类群中（Acevedo-Rodríguez & Strong，2012 年，2016 年），只有 150 种类群（包括 14 种特有种）被列入 IUCN 红色名录。我们仅使用植物标本馆数据，通过两种方法对这些岛屿特有的 263 种种子植物类群进行了初步保护评估。使用最初为评估夏威夷植物群而开发的算法（Krupnick et al. in Biodiversity and Conservation 18: 1459–1474, 2009），8% 的分类群被认为可能已经灭绝，62% 的分类群被评估为潜在威胁未受威胁。使用红色名单标准方法，70% 被视为受威胁（极危、濒危和易危），而 30% 被评估为近危、最不受关注或数据不足。这些不同方法的评估结果与 14 种红色名录物种的评估结果一致，验证了这种方法是优先考虑植物保护工作的第一步。
