DNA shows where Washington culvert replacements helped spawning salmon

A project led by the UW used genetic sleuthing to study how salmon were affected by two major culvert replacements near the city of Bellingham. One project, a major upgrade under Interstate-5, had a big impact, while the other old culvert may have been less of a barrier to fish. Authors from the UW and NOAA are studying the use of eDNA in future environmental impact reporting.
