Pacific Lamprey in the Columbia River Basin

The Pacific lamprey has recently experienced steep declines in abundance and their range has contracted along the West Coast of North America, including the Columbia River basin. An article written by 21 researchers from the Pacific Northwest provides an up-to-date synthesis of Native American tribal, federal, and local plans for managing, conserving, and restoring Pacific lamprey in the Columbia River basin. Researchers synthesized factors that limit Pacific lamprey movement and reproduction and also identified six conservation and restoration actions that can benefit Pacific lamprey: removing passage barriers, modifying diversion screens and facilities, restoring river habitats to free-flowing river ecosystems, minimizing dredging and dewatering, educating citizens about the importance of lamprey, and including lamprey in planning and implementation for instream work. Authors point out knowledge gaps such as trends in status, population dynamics, and marine influences, as well as emphasize future research and monitoring needs of lamprey in the Columbia River basin.
