英国生态与水文中心与联合自然保护委员会联合开展的一项8年长期监测显示，许多园丁视为杂草的普通植物对蜜蜂、蝴蝶等传粉昆虫具有重要价值1。其中常春藤成为传粉昆虫最受欢迎的植物，每10分钟吸引22次访问，牛皮消紧随其后获得20次访问，滨梵天花、荆棘、矢车菊和蓟平均各吸引14次访问1。
研究覆盖2017年至今的8年时间范围，发现了传粉昆虫种群的复杂变化1。悬蝇数量在这一时期内在种群规模和物种总数上都下降了约三分之一，但独居蜜蜂、蜜蜂和其他飞行昆虫的数量有所增加，表明家庭花园为部分传粉昆虫提供了重要庇护所1。蝴蝶保护组织的蝴蝶监测官Jo Milborrow评价道："这个容易生长的本地物种也是传粉昆虫访问第一名的植物是一个奇妙的发现"1。
该监测计划正在征集志愿者参与，任何人都可在2024年4月至9月期间通过传粉昆虫监测计划网站贡献观察数据1。
An eight-year study conducted across the United Kingdom has revealed that ivy is the most favored plant among pollinating insects, attracting an average of 22 insect visits every ten minutes, followed by dogwood with 20 visits and hawthorn with approximately 14 visits per ten-minute period 1. Other common plants that many gardeners dismiss as weeds—including sea holly, cornflower, and thistle—also received approximately 14 visits on average, demonstrating their significant value to bees, butterflies, and other flying pollinators 1.
The research, run by the UK Centre for Ecology and Hydrology (UKCEH) and the Joint Nature Conservation Committee (JNCC) and spanning from 2017 onwards, found a marked decline in hover fly populations, which decreased by roughly one-third in both abundance and species diversity over the eight-year period 1. However, this trend was not universal: solitary bees, honeybees, and other flying insects showed increases, indicating that gardens provide important refuge for certain pollinator species 1. Jo Milborrow, monitoring officer for the Butterfly Conservation charity, remarked on the findings, stating that "it is a wonderful discovery that this easy-to-grow native species is the plant most visited by pollinators" 1. Members of the public can contribute their own observations to the Pollinator Monitoring scheme website between April and September 2024 1.
