A beaver mitigation and monitoring group is being set up to manage potential issues.
NatureScot said it would work with Forestry and Land Scotland (FLS) on the monitoring for at least 10 years after the beavers’ release.
Chris Donald, NatureScot’s head of operations for Central Highland, said: “Beavers can bring many benefits for nature and people – including creating biodiverse habitats, moderating water flows and improving water quality – all of which can play a part in creating climate-resilient landscapes.
“After careful consideration, we believe that it is possible to realise these many benefits while ensuring that the community is supported in living with beavers.”
A small number of beavers have been living on the River Beauly system for the last decade as a result of unauthorised escapes or releases.
Beavers died out in Scotland about 400 years ago but were reintroduced in 2009.
Populations are already established in the Cairngorms, Tayside, on the Forth, in Knapdale and Loch Lomond.
