Flowering plants can enhance wild insect populations and their pollination services to crops in agricultural landscapes, especially when they flower before the focal crop. However, characterizing temporal availability of specific floral resources is a challenge.Developing an index for at landscape scale according use by pollinator. Investigating whether detailed temporally-resolved resource maps predict success broad bean better than land cover maps.We mapped plant species used as pollen source bumblebees 24 landscapes developed different times flowering season. To measure success, patches (Vicia faba), typically pollinated bumblebees, were exposed center selected landscapes.Higher led enhanced seed set. Floral synchronous had no effect. Seed set was somewhat explained availability, increasing with urban area declining arable land.The timing alternative important crop pollination. The higher explanation indicates that additional factors such habitat disturbance nesting sites play role Enhancing non-crop woody sources may ensure levels pollinators bumblebees.The online version contains supplementary material available 10.1007/s10980-022-01448-2.
