Floristic survey of vascular plants of the Pantanal Park Road in Mato Grosso do Sul, Brazil

The Pantanal is one of the largest floodplains and the most extensive tropical wetland in the world, covering approximately 139,000 km². It is located in central South America, covering areas in Bolivia, Paraguay, and the Brazilian states of Mato Grosso and Mato Grosso do Sul. Flora inventories of the Pantanal have shown a varied species richness, ranging from 1,872 to 2,567 species. The Pantanal Park Road (PPR) is an area of special tourist interest located within the Pantanal of Mato Grosso do Sul and covers 6,700 km², passing through the municipalities of Corumbá and Ladário. This data paper plays a crucial role in organizing and disseminating essential information on local flora, recognizing the value of floristic surveys for understanding regional biodiversity and informing conservation efforts. It aimed to provide information to guide public policies for preserving local biodiversity. The floristic survey was generated by combining data from field expeditions with botanical databases, such as JABOT and SpeciesLink. Additional information included life form, substrate type, conservation status, and species distribution across Brazilian biomes and states, obtained from Flora e Funga do Brasil using the flora package. Data from Flora e Funga do Brasil were also used to identify new occurrences among the listed species. The vascular plant list of the PPR included 755 species. Most species throughout the PPR were classified as herbs, followed by shrubs or subshrubs, climbers, and trees. Thirty species with a known response to fire were identified, of which eight are fire-sensitive, two are fire-tolerant, and 21 are fire-stimulated. Of the total species recorded, 710 are native to Brazil, with eight species endemics to Mato Grosso do Sul, ten to the Pantanal, and four specifically to the Pantanal in Mato Grosso do Sul. According to the Red List Category from the National Center for Plant Conservation in Brazil, the PPR contains two species classified as Data Deficient (DD), 71 as Least Concern (LC), three as Near Threatened (NT), four as Vulnerable (VU), four as Endangered (EN), and one as Critically Endangered (CR).潘塔纳尔（Pantanal）是全球规模最大的泛滥平原之一，也是最广袤的热带湿地，总面积约13.9万平方千米。其地处南美洲中部，覆盖玻利维亚、巴拉圭以及巴西马托格罗索州与南马托格罗索州的部分区域。针对潘塔纳尔的植物区系调查结果显示，该区域物种丰富度介于1872至2567种之间，物种组成丰富多样。潘塔纳尔公园道（Pantanal Park Road, PPR）是南马托格罗索州潘塔纳尔区域内极具旅游价值的特殊片区，总面积6700平方千米，途经科伦巴（Corumbá）与拉达里奥（Ladário）两座市镇。本数据论文在整理与传播当地植物区系核心信息方面发挥了关键作用，同时凸显了植物区系调查对于解析区域生物多样性、指导保护实践的重要价值，本研究旨在提供支撑数据以指导制定当地生物多样性保护的公共政策。本次植物区系调查通过整合野外考察数据与JABOT、SpeciesLink等植物学数据库完成，额外补充的信息包括植物生活型、基质类型、保护现状，以及物种在巴西各生物群系与各州的分布情况，上述数据通过flora软件包从《Flora e Funga do Brasil》数据库获取，同时依托该数据库还识别出名录收录物种中的新分布记录。潘塔纳尔公园道的维管植物名录共收录755种，该区域多数物种为草本植物，其次依次为灌木或亚灌木、藤本植物与乔木。另有30种对火具有明确响应的物种，其中8种为火敏感型，2种为耐火型，21种为火促进型。在已记录的全部物种中，710种为巴西本土物种，包含8种南马托格罗索州特有种、10种潘塔纳尔区域特有种，以及4种仅分布于南马托格罗索州境内潘塔纳尔区域的物种。根据巴西国家植物保护中心发布的红色名录等级，潘塔纳尔公园道区域内有2个物种被评定为数据缺乏（Data Deficient, DD），71个为无危（Least Concern, LC），3个为近危（Near Threatened, NT），4个为易危（Vulnerable, VU），4个为濒危（Endangered, EN），1个为极危（Critically Endangered, CR）。
