Arable weeds threaten farming and food production, impacting on productivity. Large‐scale data on weed populations are typically lacking, and changes are frequently undocumented until they reach problem levels. Managing the future spread of weeds requires that we understand the factors that influence current densities and distributions. In doing so, one of the challenges is to measure populations at a large enough scale to be able to accurately measure changes in densities and distributions. Here we analyse the density and distribution of a major weed (Alopecurus myosuroides) on a large scale. Our objectives were to (i) develop a methodology for rapid measurement of occurrence and abundance, (ii) test hypotheses about the roles of soils and climate variation in determining densities, and (iii) use this information to identify areas in which occurrence could increase in the future.

在全国范围内表征环境风险因素，说明Aurocurus myosuroides的丰度和分布

耕地杂草威胁着农业和粮食生产，影响了生产力。通常缺乏有关杂草种群的大规模数据，并且经常没有记录到变化，直到达到问题水平。管理杂草的未来传播要求我们了解影响当前密度和分布的因素。这样做的挑战之一是要以足够大的规模测量人口，以能够准确地测量密度和分布的变化。在这里，我们分析了主要杂草（Alopecurus myosuroides）的密度和分布）大范围上。我们的目标是（i）开发一种用于快速测量发生和丰度的方法，（ii）测试有关土壤和气候变化在确定密度中的作用的假设，以及（iii）使用此信息来确定发生率可能增加的区域将来。
