Invasive alien plants - map of the potential area Ludwigia peploides

The set of invasive alien plants shows the maps of the potential areas of 56 alien plants species present in Switzerland as well as some invasive species present in neighboring countries with the potential to reach Switzerland. The maps are the result of model-based tool to anticipate the spread of invasive alien plants listed on the Swiss Black and Watch list. The model is using occurrence data from GBIF (Global Biodiversity Information Facility), current climate data from Worldclim(1 km resolution) and occurrence data from InfoFlora combined with climate data from the WSL (100 m resolution).The maps with 100 m resolution utilize additional necessary variables including landuse and geology.本外来入侵植物数据集涵盖瑞士境内现存56种外来植物的潜在分布区地图，同时纳入部分在周边国家已出现且具备扩散至瑞士潜力的入侵物种的潜在分布区。此类地图依托模型工具生成，用于预测瑞士入侵物种黑名单与警戒名录中所列外来入侵植物的扩散态势。该模型采用的数据包括：全球生物多样性信息设施（Global Biodiversity Information Facility, GBIF）提供的物种出现记录、Worldclim（空间分辨率1公里）的当前气候数据，以及InfoFlora的物种出现记录与瑞士联邦森林、雪与景观研究所（WSL）提供的空间分辨率100米的气候数据。空间分辨率为100米的地图则额外引入土地利用、地质等必要变量完成绘制。
