In flat terrain and humid climates, raised bogs can form the topographic watershed boundary of protected source watersheds. In these cases, only half of the “bisected bog” is protected. We consider if these bisected bogs should be included in source water protection areas by exploring how drainage in the unprotected side of the bog may impact the protected watershed. Groundwater monitoring and slug tests were performed in a transect of piezometers in a large, bisected bog in Cape Breton, Nova Scotia, Canada to constrain a groundwater flow model. Under varying drainage scenarios (1 m, 3 m and complete harvest), simulations showed that the groundwater divide shifts 41 to 398 m inwards, 219,000 m3 to 1,570,000 m3 of water storage are lost and up to 23,600 to 156,100 tonnes of soil carbon become unstable. These findings suggest that it is illogical to protect only part of a bisected bog and that the entire bog should be protected to preserve hydrologic functionality. A GIS analysis revealed that bisected bogs are common in source water protection areas in the province. We provide recommendations for water managers to identify and address bisected wetlands to improve source water protection and maintain wetland ecosystem services.

在平坦地形与湿润气候区，隆起泥炭沼泽可构成受保护水源流域的地形分水岭边界。在此类情况下，“被分割的泥炭沼泽（bisected bog）”仅有一半受到保护。我们通过探究泥炭沼泽未受保护一侧的排水如何影响受保护流域，来思考是否应将这些被分割的泥炭沼泽纳入水源保护区。在加拿大新斯科舍省布雷顿角的一处大型被分割泥炭沼泽中，通过测压管断面开展了地下水监测与slug试验（slug test），以约束地下水流模型。在不同排水情景（1米、3米及完全采伐）下，模拟结果显示地下分水岭向内偏移41至398米，储水量损失21.9万至157万立方米，且多达2.36万至15.61万吨土壤碳变得不稳定。这些发现表明，仅保护被分割泥炭沼泽的一部分是不合逻辑的，应保护整个泥炭沼泽以维持其水文功能。地理信息系统（GIS）分析显示，被分割的泥炭沼泽在该省水源保护区中较为常见。我们为水资源管理者提供建议，以识别并处理被分割湿地，从而改善水源保护并维持湿地生态系统服务。
