摘要农田边缘栖息地在均匀的农业景观中可以起到多种作用，包括增强生物多样性，水质保护，以及有益昆虫的栖息地，如本地蜜蜂和天敌。尽管有这种生态系统服务价值，但在大规模单一作物农场采用田间边界种植，如树篱，是最小的。由于利润主要驱动农业生产，影响绿篱种植的一个主要挑战与建立成本和恢复投资缺乏明确的经济效益有关。我们的研究证明，树篱通过提高农场的益虫和自然害虫控制和授粉，对种植者来说是经济可行的。我们的模型显示，仅在虫害控制方面，一个典型的300米树篱田边种植的4,000美元成本需要16年才能从杀虫剂节省中实现收支平衡。通过增加本地蜜蜂的授粉效益，蜜蜂（意大利蜜蜂L.）可能是有限的，返回时间减少到7年。美国农业部的成本分摊计划允许更快地回报树篱投资。我们的研究表明，随着时间的推移，小规模的恢复可以是有利可图的，有助于克服与农田边缘栖息地恢复相关的成本障碍。
Abstract Field edge habitat in homogeneous agricultural landscapes can serve multiple purposes including enhanced biodiversity, water quality protection, and habitat for beneficial insects, such as native bees and natural enemies. Despite this ecosystem service value, adoption of field border plantings, such as hedgerows, on large-scale mono-cropped farms is minimal. With profits primarily driving agricultural production, a major challenge affecting hedgerow plantings is linked to establishment costs and the lack of clear economic benefits on the restoration investment. Our study documented that hedgerows are economically viable to growers by enhancing beneficial insects and natural pest control and pollination on farms. With pest control alone, our model shows that it would take 16 yr to break even from insecticide savings on the US$4,000 cost of a typical 300-m hedgerow field edge planting. By adding in pollination benefits by native bees, where honey bees (Apis mellifera L.) may be limiting, the return time is reduced to 7 yr. USDA cost share programs allow for a quicker return on a hedgerow investment. Our study shows that over time, small-scale restoration can be profitable, helping to overcome the barrier of cost associated with field edge habitat restoration on farms.
