The plan would take decades to fully implement, and it focuses on strategies such as removals of dams, installations of fish passages and increasing the number of salmon that survive in the ocean. It states that the estimated cost is about $24 million per year, not including money federal departments already spend on salmon recovery work. How that money would materialize at this point is unclear. But the plan gives the species a roadmap to recovery, said Peter Lamothe, program manager for the Maine fish and wildlife complex for the U.S. Fish and Wildlife Service. “It gives all of the partners involved in this what to shoot for — what we collectively need to achieve to recover the species,” Lamothe said. “It gives us a path forward.”
