The final part of the landmark wildlife series narrated by Ewan McGregor.

The Highlands may appear a wild and unforgiving place, but for millennia people have lived alongside wild animals here, sharing the same weather, seasons and landscapes.

For many years, the impact of humans on the landscape has been damaging, with forests cut down, seas warming and many iconic species like the wolf and bear vanishing.

But now things are changing and people are working to put back what we've lost. Humans are finding ways of protecting the Highlands' precious ospreys, eagles, red kites, seabirds and dolphins. Never before has so much work been done to restore the wild Highlands to its full glory.
