The Challenge of Reconnecting the Salmon Rivers of Wales

Habitat fragmentation caused by instream barriers is a leading cause of loss of river biodiversity and is responsible for the decline of Atlantic salmon and other migratory fish in Wales, and elsewhere.

The situation of Atlantic salmon in Wales is critical and all populations have been declared ‘at at risk’ or ‘probably at risk" by Natural Resources Wales. Our recent assessments indicate that this is in part due to the high extent of habitat fragmentation
