Restoration is used to conserve biodiversity; however, it is unclear to what extent restoration impacts ecosystem functions. Pollination is an ecosystem function that is critical to plant reproduction and thus restoration success. Few studies have assessed whether pollination is restored within restoration areas themselves. Plant–animal interactions may be affected by factors beyond the scale of the restoration. For example, surrounding landscape context may influence pollinator abundance and consequently the amount of pollen deposited. Decreased pollen receipt might then limit seed set. We hypothesized that in restorations surrounded by more agriculture, pollinator‐dependent forbs would experience greater pollen limitation. This would likely be due to declines in pollinator abundance within the restorations with an increase in surrounding agriculture. We deployed potted Chamaecrista fasciculata (Fabaceae), an obligatorily bee‐pollinated forb, and sampled bee communities in restored prairies in Minnesota, U.S.A. We measured pollen limitation by comparing seed set among open and supplementally pollinated plants. We also sampled native bees in seven of the eight sites. We tested for a relationship between proportion row crop agriculture (corn and soy) surrounding a restoration and pollen limitation, as well as an effect of agriculture on bee abundance. We did not find evidence that increasing proportion of surrounding agriculture negatively affected pollen limitation or bee abundance. Our results indicate that greater surrounding agriculture may not influence pollination of C. fasciculata through declines in pollinator availability, and suggest for some plants that landscape context might not limit pollination in restorations.

恢复后的草原中依赖蜜蜂的授粉的授粉：在行作农业主导的景观中没有花粉限制的证据

恢复用于保护生物多样性；然而，尚不清楚恢复在多大程度上影响生态系统功能。授粉是一种生态系统功能，对于植物繁殖和恢复成功至关重要。很少有研究评估授粉区域内的授粉是否恢复。植物与动物之间的相互作用可能受到恢复规模以外因素的影响。例如，周围的景观环境可能影响授粉媒介的丰度，从而影响花粉的沉积量。花粉收据减少可能会限制种子结实。我们假设在更多农业包围的恢复体中，依赖传粉媒介的禁令将经历更大的花粉限制。这可能是由于恢复区内传粉媒介丰度的下降以及周围农业的增加。我们部署盆栽Chamaecrista fasciculata（Fabaceae），一种强制授粉的蜜蜂，在美国明尼苏达州的恢复大草原中对蜜蜂群落进行采样。我们通过比较开放和补充授粉植物的种子集来测量花粉限制。我们还在八个地点中的七个地点采样了本地蜜蜂。我们测试了围绕恢复和花粉限制的比例行作物农业（玉米和大豆）之间的关系，以及农业对蜂类丰度的影响。我们没有发现证据表明周围农业的比例增加对花粉限制或蜂类数量产生负面影响。我们的结果表明，更大的周边农业可能不会影响C. fasciculata的授粉 通过降低授粉媒介的可利用性，并建议某些植物景观环境可能不会限制恢复植物的授粉。
