A recently completed study using relatively new eDNA technology shows that replacing culverts that might act as fish migration barriers is key to restoring salmon and steelhead in the Pacific Northwest. And, presumably, wherever faulty culverts interrupt salmonid migration. More broadly, however, the study is a herald for the use of eDNA science in restoration work conducted across environments and around the globe.
