North Atlantic Aquatic Connectivity Collaborative
The North Atlantic Aquatic Connectivity Collaborative (NAACC) is a network of individuals from universities, conservation organizations, and state and federal natural resource and transportation departments focused on improving aquatic connectivity across a thirteen-state region, from Maine to West Virginia.
The NAACC has developed common protocols and training for assessing road-stream crossings (culverts and bridges) and developed a regional database for this field data. The information collected will be used to identify high priority bridges and culverts for upgrade and replacement.
The NAACC will support planning and decision making by providing information about where restoration projects are likely to bring the greatest improvements in aquatic connectivity. The NAACC has created a subwatershed prioritization map to help focus survey efforts in the project area, as well as a customizable prioritization tool for use with ArcGIS Desktop.
