在农业用地上，恢复栖息地以促进野生传粉者种群越来越普遍。然而，人们对野生蜜蜂，全球最重要的野生授粉者，如何利用恢复栖息地的资源知之甚少。我们比较了蜜蜂在两种类型的恢复的本土植物篱中对本土和外来植物的利用：成熟的植物篱（建立后>10年），旨在增加天敌，新的植物篱（建立后≤2年），旨在增加蜜蜂种群。蜜蜂从花收集定时空中网和开花植物覆盖估计物种覆盖类。在成熟的绿篱网站，野生蜜蜂的丰度，丰富性和多样性更大的本地植物比外来植物。在新地点，本土植物很小，花卉展示有限，本土植物上的蜜蜂数量比外来植物上的蜜蜂数量更多;但是，控制花卉覆盖，两种植物类型之间的蜜蜂多样性和丰富度没有差异。在成熟的和新的树篱，野蜂更喜欢从本地植物比外来植物觅食。蜜蜂，这是从管理殖民地，也喜欢本地植物在成熟的绿篱网站，但没有表现出偏好在新的网站。我们的研究表明，野生蜜蜂和管理蜜蜂在某些情况下，更喜欢在灌木篱笆中的本地植物上觅食，而不是同时出现的杂草，外来植物。半定量排名确定了哪些本土植物是最受欢迎的。在农业区，用本土植物恢复绿篱可能有助于提高野生蜜蜂的丰度和多样性，并保持蜜蜂的健康。
Habitat restoration to promote wild pollinator populations is becoming increasingly common in agricultural lands. Yet, little is known about how wild bees, globally the most important wild pollinators, use resources in restored habitats. We compared bee use of native and exotic plants in two types of restored native plant hedgerows: mature hedgerows (>10 years from establishment) designed for natural enemy enhancement and new hedgerows (≤2 years from establishment) designed to enhance bee populations. Bees were collected from flowers using timed aerial netting and flowering plant cover was estimated by species using cover classes. At mature hedgerow sites, wild bee abundance, richness, and diversity were greater on native plants than exotic plants. At new sites, where native plants were small and had limited floral display, abundance of bees was greater on native plants than exotic plants; but, controlling for floral cover, there was no difference in bee diversity and richness between the two plant types. At both mature and new hedgerows, wild bees preferred to forage from native plants than exotic plants. Honey bees, which were from managed colonies, also preferred native plants at mature hedgerow sites but exhibited no preference at new sites. Our study shows that wild bees, and managed bees in some cases, prefer to forage on native plants in hedgerows over co‐occurring weedy, exotic plants. Semi‐quantitative ranking identified which native plants were most preferred. Hedgerow restoration with native plants may help enhance wild bee abundance and diversity, and maintain honey bee health, in agricultural areas.
