Taxus baccata chorology

Distribution map of European yew (<i>Taxus baccata</i>)<br><br>These maps were produced by combining numerous and heterogeneous data collected from atlas monographs providing complete species distribution maps, from national to regional atlases, occurrence geo-databases, scientific and grey literature.<br>The maps were created using ESRI shapefiles (*.shp, *.shx, *.dbf, *.prj files) archived in the ZIP file. Species range is mapped with polygon features (name suffix "plg"), which define continuous areas of occupancy of the species, and with point features (name suffix "pnt"), which identify more fragmented and isolated populations. If synanthropic occurrences are reported outside the species natural range, additional point and/or polygon shapefiles are also present (suffix "syn"). <br>Polygon borders delimiting species ranges are generalized across the mainland and sea boundaries. This offers the possibility to mask sea areas or to clip and extract the terrestrial range parts using GIS data layers of the users' choice. An additional version of polygon ranges are clipped with a coastline (name suffix "clip"), which have been derived from Natural Earth dataset "Admin 0 - Countries" 1:50M version 4.1.0 (https://www.naturalearthdata.com). <br><br>Please cite as:<br>Caudullo, G., Welk, E., San-Miguel-Ayanz, J., 2017.

欧洲红豆杉（Taxus baccata）分布图谱

本数据集的分布图谱通过整合多源异构数据编制而成，数据来源涵盖完整呈现物种分布格局的国家级至区域级植物志图集、物种出现点地理数据库，以及学术文献与灰色文献。

本图谱以ESRI形状文件（ESRI shapefiles，包含*.shp、*.shx、*.dbf、*.prj格式文件）打包存储于ZIP压缩包内。物种分布范围通过两类空间要素进行可视化：其一为多边形要素（文件名后缀为“plg”），用于界定物种的连续栖息区域；其二为点要素（文件名后缀为“pnt”），用于标识更为破碎孤立的种群。若在物种自然分布范围外记录有与人伴生的出现记录，则将附带额外的点/多边形形状文件（后缀为“syn”）。

用于界定物种分布范围的多边形边界已针对陆地与海洋边界进行了概化处理，支持用户通过自定义GIS数据图层掩膜海洋区域，或裁切提取陆地分布范围。此外还提供了经海岸线裁切的多边形范围版本（文件名后缀为“clip”），该数据集源自Natural Earth数据集“Admin 0 - Countries”1:50M 4.1.0版本（https://www.naturalearthdata.com）。
