昆虫传粉者的丰度，特别是蜜蜂的丰度，已经被证明是高的，那里有一个超级丰富的花卉资源;例如，在与大量开花的作物，也在花园中，开花植物往往密集种植。由于土地管理影响传粉者的数量，因此也可能影响到生长在这些生境中的植物的授粉。我们假设，两种植物物种的种子或坐果，通常由熊蜂和/或蜜蜂授粉，可能会以两种方式之一作出反应：1）在开花环境中生长时，通过对传粉者的竞争，授粉成功率可能会降低，或者2）由于附近传粉者丰度的增加，授粉成功率可能会提高。比较了三种实验植物的授粉成功率。和百脉根Lotus corniculatus L.生长在花园和耕地。在农场里，这些植物被放置在大量开花的作物（油菜，甘蓝型油菜L。或蚕豆（Vicia faba L.）或靠近谷类作物（小麦，小麦属（Triticum spp.））。种子集G.常春藤属植物和L.结果表明，菜园中小角海蜇的生长量显著高于农田。授粉成功率与对照无显著差异。常春藤在不同的作物旁生长时，但L.小油菜开花时，与油菜相邻生长的植株坐果率较高。结果表明，授粉服务可以限制可耕地中野生植物的坐果，但有一些证据表明，开花作物的存在可以促进它们的授粉（取决于物种和季节）。我们还证明了花园不仅有利于传粉者，而且有利于授粉过程。
Insect pollinator abundance, in particular that of bees, has been shown to be high where there is a super-abundance of floral resources; for example in association with mass-flowering crops and also in gardens where flowering plants are often densely planted. Since land management affects pollinator numbers, it is also likely to affect the resultant pollination of plants growing in these habitats. We hypothesised that the seed or fruit set of two plant species, typically pollinated by bumblebees and/or honeybees might respond in one of two ways: 1) pollination success could be reduced when growing in a floriferous environment, via competition for pollinators, or 2) pollination success could be enhanced because of increased pollinator abundance in the vicinity. We compared the pollination success of experimental plants of Glechoma hederacea L. and Lotus corniculatus L. growing in gardens and arable farmland. On the farms, the plants were placed either next to a mass-flowering crop (oilseed rape, Brassica napus L. or field beans, Vicia faba L.) or next to a cereal crop (wheat, Triticum spp.). Seed set of G. hederacea and fruit set of L. corniculatus were significantly higher in gardens compared to arable farmland. There was no significant difference in pollination success of G. hederacea when grown next to different crops, but for L. corniculatus, fruit set was higher in the plants growing next to oilseed rape when the crop was in flower. The results show that pollination services can limit fruit set of wild plants in arable farmland, but there is some evidence that the presence of a flowering crop can facilitate their pollination (depending on species and season). We have also demonstrated that gardens are not only beneficial to pollinators, but also to the process of pollination.
