(CNN)On the edge of the Scottish Highlands, three families of beavers slip, slide and splash between a series of ponds and swamps at the Bamff estate. The animals have been breeding there for almost two decades, brought in by Paul and Louise Ramsay who own the estate, and are now establishing themselves in the wild.
The Ramsays are often credited as pioneers in the reintroduction of Eurasian beavers, which are native to the UK but were hunted to extinction there during the 16th century. They are just the first chapter in what is now a nationwide rewilding movement.
As Scotland hosts the COP26 climate summit in Glasgow, calls on the government to support rewilding, regenerate peatland and reintroduce lost species are becoming louder -- and the potential benefits becoming clearer.
