With support from the North Atlantic LCC and Hurricane Sandy Disaster Mitigation funds the North Atlantic Aquatic Connectivity Collaborative (www.streamcontinuity.org) has developed a regional crossing assessment protocol and database, scoring systems for aquatic organism passage, and hydraulic risk of failure assessments based on future storm discharge levels. The existing NAACC protocol was developed primarily for freshwater streams and the suite of organisms that occur in these systems. There is strong interest among conservation practitioners to have a method to assess tidally influenced crossings for their potential as barriers to aquatic organism passage. Protocols designed for freshwater streams will not...

Rivers and streams are highly vulnerable to fragmentation from roads due to their prevalence in the landscape. Road-stream crossings are far more numerous than other anthropogenic barriers such as dams; these crossing structures (culverts, bridges, fords, and tide gates) have been demonstrated to impede the passage of aquatic organisms. However, road-stream crossings vary widely in the extent to which they serve as a barrier. It is important to identify barrier severity to facilitate prioritization of restoration activities, since proactively addressing all structures is not feasible. In 2015 the North Atlantic Landscape Conservation Collaborative (LCC) funded a project managed by the North Atlantic Aquatic Connectivity...
