Restoring degraded salmon rivers through riparian planting, gravel augmentation, and barrier removal improves welfare for salmon and the full range of wildlife that depends on healthy rivers.
Salmon habitat restoration improves welfare directly by reducing the physiological stress of high water temperatures, removing physical barriers that cause exhausting and injury-prone migration attempts, and restoring the clean spawning gravel that ensures egg development success. Individual salmon living in restored rivers face lower chronic stress, better nutritional conditions, and higher reproductive success. The welfare benefits extend beyond salmon: otters, kingfishers, dippers, and countless invertebrate species that depend on healthy rivers benefit from the same habitat improvements. Restoration projects that integrate agricultural advice, tree planting, and barrier removal deliver welfare improvements across entire river catchments and the wildlife communities they support.
