Riparian vegetation structure data for three intensively studied Wessex chalkstream sites, England, UK

A measure of the extent and complexity of riprian vegetation upstream of chalkstream sites derived from Light Detection and Ranging (LiDAR) data for three chalkstream sites within the Wessex chalk area (River Till, River Wylye and Nine Mile River). For each site there is an estimate of the minimum, maximum, mean and standard deviation height of vegetation along the banks for a range of distances upstream from the sampling location. Information on the extent and complexity of riparian vegetation upstream of chalkstream sites were used to better understand the relationships between in-stream biological communities and catchment and riparian land use. Stream sites surveyed represented a sample of chalkstreams across a gradient of catchment land cover intensification from catchments dominated by extensive calcareous grassland and woodland (Nine Mile River) to those dominated by arable and improved grasslands (Wylye). LiDAR data were obtained from the Environment Agency in April 2014. This dataset was created as part of work package 3.2 of the Wessex Biodiversity & Ecosystem Service Sustainability (BESS) project.

本数据集衡量了白垩溪上游植被的广度和复杂性，该数据来源于对位于威塞克斯白垩地区的三个白垩溪地点（泰尔河、惠利河和九英里河）的光探测与测距（LiDAR）数据。对于每个地点，均提供了植被沿河岸在采样点上游不同距离处的最小值、最大值、平均值和标准差高度估计。关于白垩溪上游植被的广度和复杂性信息，被用于更深入理解河中生物群落与流域及河岸土地利用之间的关系。所调查的溪流地点代表了从以广袤的钙质草地和林地为主的流域（九英里河）到以耕作和改良草地为主的流域（惠利河）的 chalkstream 的样本。LiDAR 数据于 2014 年 4 月从环境署获取。本数据集是作为威塞克斯生物多样性及生态系统服务可持续性（BESS）项目第 3.2 工作包的一部分创建的。关于此数据集的详细信息可在 https://doi.org/10.5285/61170f63-5ce0-43e3-8b0e-49c5a47bd3d0 查阅。
