摘要：气候变化正在改变稀有植物的生长环境。评估物种对气候变化的脆弱性对于负责管理自然区域和保护稀有物种的组织来说非常重要。我们使用两种方法评估了美国西部 34 种稀有植物类群的气候变化脆弱性：NatureServe 的气候变化脆弱性指数 (CCVI) 和一种基于使用 Maxent 的物种分布模型 (SDM) 的方法。在 CCVI 归类为极度脆弱的八个类群中，有 5 个类群在三项 SDM 措施中均显示出未来的重大损失：适宜区域的变化、适宜区域重叠以及当前位置的栖息地适宜性。 CCVI和SDM都是评估气候变化脆弱性的重要工具；每种方法都有互补的优势，可以帮助土地管理者做出决策。在这里，我们举例说明土地管理者如何结合使用 SDM 和 CCVI 来评估气候变化脆弱性、为稀有植物管理决策提供信息并保护生物多样性。
ABSTRACT: Climate change is altering environments where rare plants grow. Assessing species' vulnerability to climate change is important for organizations responsible for managing natural areas and conserving rare species. We assessed the climate change vulnerability of 34 rare plant taxa from the western United States using two methods: NatureServe's Climate Change Vulnerability Index (CCVI) and one based on Species Distribution Modeling (SDM) using Maxent. Of the eight taxa categorized as Extremely Vulnerable by the CCVI, five show significant future loss in each of three SDM measures: change in suitable area, suitable area overlap, and habitat suitability in their present location. Both the CCVI and SDM are important tools to assess climate change vulnerability; each method has complementary strengths that can help land managers make decisions. Here we present examples of how land managers can use SDM and the CCVI in combination to assess climate change vulnerability, to inform rare plant management decisions, and to conserve biological diversity.
