FLS and its project partner, conservation charity Trees for Life, said they had carried out two years of consultation with local communities and land managers.
Euan Wiseman, FLS north region planning manager, said: “Over the years we have built up good working relationships with the local Affric communities so it was important that we took the time to fully engage with everyone on this issue.”
He added: “We have now put appropriate measures in place that have enabled us to make a formal application to NatureScot for a release licence.”
Alan McDonnell, Trees for Life’s head of nature restoration, added: “Should the application be approved, we will be ready to offer practical support to ensure the local community can enjoy and benefit from beavers being brought back to the glen, with any localised issues well-managed.”
