1. The mutualistic interactions of plant‐pollinator networks provide myriad economic, ecological, and cultural constituents without which there would be severe environmental and societal consequences. Plant‐pollinator networks are becoming increasingly vulnerable to disturbance through intensifying anthropogenic land use and climate change.
2. Wild bees are central to pollination and documenting unique regional interactions between wild bees and floral hosts provides powerful insights into local ecology and biodiversity in addition to the potential to detect temporal network variation.
3. This study characterises the changes in a northern New England wild bee plant‐pollinator network over the past 125 years and reveals a striking increase in exotic bee and plant taxa over time. Here we document that declining wild bee species have historic ties to threatened and endangered plant species. These data provide a rare insight into the fragile nature of plant‐pollinator networks.
4. Notable specialist interactions between native taxa that were recorded in historical networks have been lost, most likely due to local extirpation of these now threatened and endangered plant species. Subsequent monitoring and conservation efforts focused on habitat restoration for declining wild bee and plant taxa are fundamental to the future preservation of regional native diversity.

野蜂的减少与植物授粉网络的变化和植物物种的引进有关

1. 植物-授粉媒介网络的相互影响提供了无数的经济，生态和文化成分，否则，将给环境和社会带来严重后果。通过加强人为土地利用和气候变化，植物授粉网络越来越容易受到干扰。
2. 野生蜂是授粉的中心，记录野生蜂和花宿主之间独特的区域相互作用，不仅可以发现时空网络的变化，还可以提供对当地生态和生物多样性的有力见解。
3. 这项研究描述了过去125年中新英格兰北部野生蜂植物传粉媒介网络的变化，并揭示了随着时间的推移，外来蜂和植物分类群的显着增加。在这里，我们记录到，野生蜂物种的减少与受威胁和濒危的植物物种有着历史联系。这些数据为植物授粉媒介网络的脆弱性提供了难得的见解。
4. 历史网络中记录的本地分类单元之间的显着专家交互已经丢失，这很可能是由于这些濒临灭绝的植物物种在当地的灭绝。随后的监测和保护工作着重于减少野生蜂和植物类群的栖息地恢复，这对于将来保护区域本地生物多样性至关重要。
