The management of protected areas (PAs) is widely used in the conservation of endangered plant species under climate change. However, studies that have identified appropriate PAs for endangered fern species are rare. To address this gap, we must develop a workflow to plan appropriate PAs for endangered fern species that will be further impacted by climate change. Here, we used endangered fern species in China as a case study, and we applied conservation planning software coupled with endangered fern species distribution data and distribution modeling to plan conservation areas with high priority protection needs under climate change. We identified appropriate PAs for endangered fern species under climate change based on the IUCN protected area categories (from Ia to VI) and planned additional PAs for endangered fern species. The high priority regions for protecting the endangered fern species were distributed throughout southern China. With decreasing temperature seasonality, the priority ranking of all endangered fern species is projected to increase in existing PAs. Accordingly, we need to establish conservation areas with low climate vulnerability in existing PAs and expand the conservation areas for endangered fern species in the high priority conservation regions.
保护区管理在气候变化背景下濒危植物物种的保护中被广泛应用。然而，针对濒危蕨类植物确定合适保护区的研究却很少。为填补这一空白，我们必须开发一种工作流程，为将受到气候变化进一步影响的濒危蕨类植物规划合适的保护区。在此，我们以中国的濒危蕨类植物物种为例进行研究，并应用保护规划软件，结合濒危蕨类植物物种分布数据和分布建模，来规划在气候变化下具有高优先保护需求的保护区。我们根据世界自然保护联盟（IUCN）的保护区类别（从Ia到VI），确定了气候变化下濒危蕨类植物物种的合适保护区，并为濒危蕨类植物物种规划了额外的保护区。保护濒危蕨类植物物种的高优先区域分布在中国南方各地。随着温度季节性变化的降低，预计所有濒危蕨类植物物种在现有保护区中的优先等级都会提高。因此，我们需要在现有保护区中建立气候脆弱性低的保护区，并在高优先保护区域扩大濒危蕨类植物物种的保护区。
