Don’t Salmon and Beavers live together in Norway where there are major Salmon fisheries?
No. The main Beaver and Salmon areas of Norway are in different parts of the country. The main Salmon rivers are in the west and north of Norway whilst Beavers are in the centre and east. In the south where Salmon have been wiped out of many rivers by acid rain, there is obviously little scope for interaction between the species. When Beavers do cause a problem in Norway they can be removed by hunting which was a prime reason for their introduction. The physical differences between the Norwegian and Scottish landscapes must also be remembered. In steep, mountainous areas, Salmon spawning is largely confined to the main channels of rivers, which are too wide for Beavers to dam. Tributaries in such areas are generally too steep for Salmon to use or are blocked by waterfalls. In flatter landscapes however, tributaries are much more accessible to Salmon allowing them to spread through the landscape into streams only a couple of metres wide.
