作物管理和农业土地利用对适应耕地生境的植物的威胁状况的影响进行了分析，使用来自29个欧洲国家的国家专家评估的维管植物红色名录的数据。每个国家的小麦产量与稀有、受威胁或最近灭绝的可耕地植物物种的数量呈正相关。在不同的威胁类别的物种的相对比例的差异显着解释使用化肥和除草剂的使用相结合，与更大的百分比的方差分配到肥料。适应个别作物的特殊物种，例如亚麻，是受到威胁最严重的物种之一。这些物种在整个欧洲都在减少，因为它们所依赖的作物种植面积减少了。农业化学品的使用越来越多，特别是在中欧和西北欧，选择了一个更大的物种群体适应生境与中等生育力。迫切需要实施成功的保护战略，以阻止欧洲植物群这一功能独特且日益受到威胁的组成部分的衰落。
The impact of crop management and agricultural land use on the threat status of plants adapted to arable habitats was analysed using data from Red Lists of vascular plants assessed by national experts from 29 European countries. There was a positive relationship between national wheat yields and the numbers of rare, threatened or recently extinct arable plant species in each country. Variance in the relative proportions of species in different threat categories was significantly explained using a combination of fertilizer and herbicide use, with a greater percentage of the variance partitioned to fertilizers. Specialist species adapted to individual crops, such as flax, are among the most threatened. These species have declined across Europe in response to a reduction in the area grown for the crops on which they rely. The increased use of agro-chemicals, especially in central and northwestern Europe, has selected against a larger group of species adapted to habitats with intermediate fertility. There is an urgent need to implement successful conservation strategies to arrest the decline of this functionally distinct and increasingly threatened component of the European flora.
