Pacific Lamprey (Entosphenus tridentatus) have been an important part of the ecological community and co-evolved with aquatic species of the western rivers of the United States. Scarce information on Pacific Lamprey has hindered conservation and management efforts. To assess and conserve Pacific Lamprey, we developed a conservation initiative composed of three parts: assessment, conservation agreement, and regional implementation plans. We applied a novel ranking system that characterized risk to Pacific Lamprey throughout the U.S. range. We found that the majority of watersheds are at relatively high risk of extirpation, with few secure. The risk assessment results were instrumental in gaining partners’ support for a conservation agreement, with the goal of achieving long-term persistence and supporting traditional tribal cultural use of Pacific Lamprey. This extensive support has led to a collaborative effort in developing implementation plans and delivering numerous conservation actions. This approach for assessing Pacific Lamprey status and identifying restoration priorities is easily transferable to other species. by Christina Wang and Howard Schaller Access your special Members-Only content →
