Don’t Beavers dislike the fast-flowing rivers and burns that are suitable for trout and salmon juveniles?
No. On smaller streams, the water velocities preferred by both Beavers and spawning Salmonids are similar. A Norwegian study actually found that Beavers preferred the Salmon spawning areas on small tributaries to colonise. This means that a map of where salmon spawn on smaller streams is also a map of where Beavers will prefer to set up home on such streams.
