水生恢复工作的一个关键挑战是记录被水坝或道路（道路交叉口）穿过的水体中生态连通性被破坏的位置。为了优先考虑旨在恢复连通性的行动，我们认为，有必要在区域和国家范围内对这些潜在障碍进行系统的清查。在这里，我们解决这个限制，为北美五大湖流域的最佳空间数据的位置上的水坝和道路交叉口编译。我们的空间数据库记录了五大湖流域中38倍于水坝的道路交叉口，案例研究表明，平均而言，该地区只有36%的道路交叉口完全可以捕鱼。因此，决策者在试图恢复水生生态系统的连通性时，必须考虑到道路交叉口和水坝。鉴于道路交叉口结构通常作为道路维护的一部分进行升级，因此存在许多机会来恢复...
A key challenge in aquatic restoration efforts is documenting locations where ecological connectivity is disrupted in water bodies that are dammed or crossed by roads (road crossings). To prioritize actions aimed at restoring connectivity, we argue that there is a need for systematic inventories of these potential barriers at regional and national scales. Here, we address this limitation for the North American Great Lakes basin by compiling the best available spatial data on the locations of dams and road crossings. Our spatial database documents 38 times as many road crossings as dams in the Great Lakes basin, and case studies indicate that, on average, only 36% of road crossings in the area are fully passable to fish. It is therefore essential that decision makers account for both road crossings and dams when attempting to restore aquatic ecosystem connectivity. Given that road crossing structures are commonly upgraded as part of road maintenance, many opportunities exist to restore connections within a...
