Plant diversity and indicator values within 200m radius of the Landklif plots

Species numbers of vascular plants as assessed in vegetation surveys inside and within 200m radius of the Landklif plots. Vegetation inside the plots was sampled between mid-May and end of July 2019 (seven subplots, 10m2 sampling area per plot). Cover values for each species were estimated following the Braun-Blanquet scale. Species pools within 200m radius around the plot were assessed between mid-May and begin of August 2020 by standardized transect walks (walking time proportional to area percentages of dominant habitat types within 200m radius, 60 minutes total walking time in each circle). The dataset contains average species numbers of the subplots, total species numbers of the plots, and total species numbers within 200m radius of the plots, as well as mean Ellenberg indicator values on plot and 200m scale. LandKlif is funded by the Bavarian State Ministry of Science and the Arts within the Bavarian Climate Research Network (bayklif). Within the five year funding period of bayklif, five interdisciplinary senior research associations and five junior research groups are be financed with a total sum of 18 million Euro. LandKliF, as one of the five interdisciplinary senior research associations, addresses the effects of climate change on biodiversity and ecosystem services in semi-natural, agricultural and urban landscapes.本数据集涵盖LandKlif样地内部及样地周边200米半径范围内植被调查所得的维管植物物种数量数据。2019年5月中旬至7月末，研究人员对样地内部植被进行采样：每个样地设置7个10平方米的小样方作为采样单元。各物种的盖度值均依据布朗-布朗凯（Braun-Blanquet）盖度等级法进行估算。2020年5月中旬至8月初，研究人员通过标准化样带遍历法对样地周边200米半径范围内的物种库开展调查：遍历时长与200米半径范围内优势生境类型的面积占比成正比，每个圆周区域的总遍历时长为60分钟。本数据集包含小样方的平均物种数、样地总物种数、样地周边200米半径范围内的总物种数，以及样地和200米尺度下的平均埃伦贝格（Ellenberg）指示值。 LandKlif项目由巴伐利亚州科学与艺术部依托巴伐利亚气候研究网络（bayklif）资助。在bayklif为期5年的资助周期内，该网络共资助5个跨学科资深研究联合体与5个青年研究团队，总资助金额达1800万欧元。作为5个跨学科资深研究联合体之一，LandKlif聚焦气候变化对半自然、农业及城市景观中生物多样性与生态系统服务的影响。
