Linnaeus' wild plants are under threat in Uppsala

Many of the plant species found by Carl Linnaeus and his students around Uppsala during the excursions Herbationes Upsalienses are extant in the areas they visited. The authors here present the first complete list of species registered during these excursions, with added information on extant species in the different areas. These Linnaean populations are of high cultural value, but they also have a high scientific value as potential type specimens. Three of Linnaeus’ excursion areas are therefore proposed to be included in the planned world heritage nomination \"The Rise of Systematic Biology\": Hågadalen, Årike Fyris and Fäbodmossen. The Linnaean populations are threatened by genetic pollution through the extensive sowing and planting of the same species with alien origin in connection with plant restauration after ground preparations and building. The degree of genetic pollution is not known, since sowing and planting of alien material is not registered. The authors give examples of alt...

卡尔·林奈（Carl Linnaeus）及其学生在乌普萨拉（Uppsala）周边开展名为《乌普萨拉植物考察》（Herbationes Upsalienses）的考察活动时发现的诸多植物物种，如今仍存活于他们当年到访的区域。本文作者首次整理并呈现了这些考察中登记的物种的首份完整名录，并补充了不同区域现存物种的相关信息。这些林奈植物种群兼具极高的文化价值与科研价值，其作为潜在模式标本（type specimens）的科研潜力尤为突出。因此，研究团队提议将林奈的三处考察区域——哈格达伦（Hågadalen）、奥里克菲里斯（Årike Fyris）以及费博德沼泽（Fäbodmossen）——纳入拟申报的世界遗产项目"系统生物学的兴起"（The Rise of Systematic Biology）。这些林奈植物种群正面临遗传污染（genetic pollution）的威胁：当地在场地整理与建筑施工后开展植被修复时，大量播种、栽植了外来起源的同种植物，由此引发了遗传污染。但由于外来植物材料的播种与栽植未被登记备案，当前遗传污染的具体程度尚不明确。作者还列举了关于……的示例
