Providing historical data on riparian plant biodiversity and physico-chemical parameters of stream water in Mediterranean mountains helps to assess the effects of climate change and other human stressors on these sensitive and critical ecosystems. This database collects data from the main natural headwater streams of the Sierra Nevada (southeastern Spain), a high mountain (up to 3479 m above sea level [m asl]) recognized as a biodiversity super hotspot in the Mediterranean basin. On this mountain, rivers and landscapes depend on snowmelt water, representing an excellent scenario for evaluating global change's impacts. This dataset covers first- to third-order headwater streams at 41 sites from 832 to 1997 m asl, collected from December 2006 to July 2007. Our goal is to supply information on the vegetation associated with streambanks, the essential physico-chemical parameters of stream water, and the physiographic features of the subwatersheds. Riparian vegetation data correspond to six plots sampled at each site, including total canopy, individual number, height and DBH (diameter at breast height) in woody species, and cover percentage for herbs. Physico-chemical parameters were measured in situ (electric conductivity, pH, dissolved O concentration, stream discharge) and determined in the laboratory (alkalinity, soluble reactive phosphate-phosphorus [SRP], total phosphorus [TP], nitrate-nitrogen [ -N], ammonium-nitrogen [ -N], total nitrogen [TN]). Watershed physiographic variables comprise drainage area, minimum altitude, maximum altitude, mean slope, orientation, stream order, stream length, and land cover surface percentage. We recorded 197 plant taxa (67 species, 28 subspecies, and 2 hybrids), representing 8.4% of the Sierra Nevada vascular flora. Due to the botanical nomenclature used, the database can be linked to FloraSNevada database, contributing to Sierra Nevada (Spain) as a laboratory of global processes. This data set can be freely used for non-commercial purposes. Users of these data should cite this data paper in any publications resulting from its use.
提供地中海山区河岸植物生物多样性及溪流水理化参数的历史数据，有助于评估气候变化和其他人类压力源对这些敏感且关键的生态系统的影响。该数据库收集了西班牙东南部内华达山脉主要天然源头溪流的数据，这座高山（海拔高达3479米）被公认为地中海盆地的生物多样性超级热点地区。在这座山上，河流和地貌依赖融雪水，是评估全球变化影响的绝佳场景。该数据集涵盖了海拔832至1997米的41个站点的一至三级源头溪流，数据收集时间为2006年12月至2007年7月。我们的目标是提供与河岸相关的植被信息、溪流水的基本理化参数以及次流域的地貌特征。河岸植被数据对应于每个站点采样的六个样地，包括木本物种的总树冠层、个体数量、高度和胸径，以及草本植物的覆盖百分比。理化参数在现场测量（电导率、pH值、溶解氧浓度、溪流流量），并在实验室测定（碱度、可溶性活性磷 - 磷[SRP]、总磷[TP]、硝酸盐 - 氮[ -N]、铵 - 氮[ -N]、总氮[TN]）。流域地貌变量包括流域面积、最低海拔、最高海拔、平均坡度、方向、溪流等级、溪流长度和土地覆盖表面百分比。我们记录了197个植物分类单元（67种、28亚种和2个杂种），占内华达山脉维管植物区系的8.4%。由于所使用的植物命名法，该数据库可与内华达山脉植物数据库链接，为将西班牙内华达山脉作为全球过程的实验室做出贡献。此数据集可免费用于非商业目的。使用这些数据的用户应在因使用该数据而产生的任何出版物中引用本数据论文。
