California project boosts salmon survival with beaver-like dams

California built beaver-like dams in coho creeks; survival rose from 8% to 60% after restoration

Innovative restoration initiatives that emulate beaver dams have drastically enhanced coho salmon survival rates, boosting juvenile survival in a specific creek from eight percent to sixty percent. By generating cooler, slower water environments, these structures are essential for nurturing young salmon. Furthermore, these revitalized areas bolster resistance to drought conditions within the Scott River watershed, underscoring the necessity of reinstating vital wetland habitats for at-risk sa...
