Environmental DNA is an effective tool to track recolonizing migratory fish following large‐scale dam removal
Abstract Environmental DNA (eDNA) has emerged as a potentially powerful tool for use in conservation and resource management, including for tracking the recolonization dynamics of fish populations. We used eDNA to assess the effectiveness of dam removal to restore fish passage on the Elwha River in...
