AB  - Diadromous fish populations are strongly affected by in-stream barriers that 
      cause river network fragmentation, constraining productivity or preventing 
      completion of their lifecycle. Removal or reduction of barrier impacts is a 
      restoration measure associated with unambiguous benefits. Management of barriers 
      is therefore often prioritised above other restoration actions. Barrier 
      management is prioritised at local and national scales depending on funding. 
      However, barrier prioritisation is potentially sub-optimal because existing tools 
      do not consider habitat quality. Furthermore, effects of partial barriers (those 
      passable under certain conditions) are uncertain, depending on location and 
      potential cumulative effects. A framework is presented for assessing effects of 
      impassable manmade barriers (IMBs) on longitudinal river network connectivity 
      (percentage of upstream habitat accessible from the river mouth) for Atlantic 
      salmon across spatial scales, using Scotland as an example. The framework 
      integrates juvenile habitat quality and network connectivity models to (1) 
      provide information necessary for local and national prioritisation of barriers, 
      and (2) assess potential effects of passable manmade barriers (PMBs) within a 
      sensitivity framework. If only IMBs are considered, high levels of longitudinal 
      connectivity are observed across most of Scotland's rivers. Barrier 
      prioritisation is sensitive to habitat weighting: not accounting for habitat 
      quality can lead to over- or underestimating the importance of IMBs. 
      Prioritisation is also highly sensitive to the passability of PMBs: if 
      passability drops to <97% (combined up- and downstream passability), the mean 
      effect of PMBs becomes greater than IMBs at the national level. Moreover, impacts 
      on catchment connectivity, and thus production (number of juvenile salmon 
      produced by the river), could be severe, suggesting a better understanding of the 
      passability of PMBs is important for future management of migration barriers. The 
      presented framework can be transferred to other catchments, regions, or countries 
      where necessary data are available, making it a valuable tool to the broader 
      restoration community.
