世界自然保护联盟抽样红色名录指数（SRLI）是生物多样性科学家对需要估计世界生物多样性减少的灭绝风险趋势的政策反应。SRLI项目的植物物种评估主要依赖于自然历史收集的植物标本数据，绝大多数植物物种都缺乏准确的种群数据或详细的分布图。这给重新评估这些物种以衡量保护状况的真正变化带来了困难，必须在相同的红色名录标准下观察保护状况的真正变化，以便与该物种现有知识的增加区分开来，从而重新计算SRLI。然而，相同的标本数据确定受威胁的物种以前被收集的精确地点，可以用来模拟物种的范围，并有针对性的实地考察，以测试基于生物多样性的范围估计和收集人口数据的SRLI植物物种。在这里，我们概述了一个战略，优先考虑实地工作，以应用更广泛的世界自然保护联盟红色名录标准的评估植物物种，或任何类群的详细地点或自然历史标本数据，产生更强大的估计SRLI。
The IUCN Sampled Red List Index (SRLI) is a policy response by biodiversity scientists to the need to estimate trends in extinction risk of the world's diminishing biological diversity. Assessments of plant species for the SRLI project rely predominantly on herbarium specimen data from natural history collections, in the overwhelming absence of accurate population data or detailed distribution maps for the vast majority of plant species. This creates difficulties in re-assessing these species so as to measure genuine changes in conservation status, which must be observed under the same Red List criteria in order to be distinguished from an increase in the knowledge available for that species, and thus re-calculate the SRLI. However, the same specimen data identify precise localities where threatened species have previously been collected and can be used to model species ranges and to target fieldwork in order to test specimen-based range estimates and collect population data for SRLI plant species. Here, we outline a strategy for prioritizing fieldwork efforts in order to apply a wider range of IUCN Red List criteria to assessments of plant species, or any taxa with detailed locality or natural history specimen data, to produce a more robust estimation of the SRLI.
