The Scottish Government has not given specific consideration to the implications of recent flooding on wild salmon populations. High river flows potentially wash out salmon eggs from nests on the riverbed and displace juvenile fish downstream. However, research suggests that salmon are well adapted to natural flow variability, including floods in natural river systems. Current evidence suggests a periodic trend towards more extreme flows in some Scottish rivers. With climate change scenarios, there is potential for further increases in high flows which may impact on salmon.

Heavily modified rivers are likely to be less resilient to potential disturbance. Restoration of natural morphological processes and channel characteristics could improve resilience. The Wild Salmon Strategy covers five priority areas, including ‘improving the condition of rivers and giving salmon free access to cold, clean water.’ The Scottish Government’s Nature Restoration Fund (NRF) specifically encourages projects to restore wildlife and habitats.
