Reintroducing wolves in the Scottish Highlands could lead to an expansion of native woodland which could take in and store one million tonnes of CO2 per year, environmental researchers have suggested.
A study led by researchers at the University of Leeds said reintroducing the species into the Cairngorms, south-west, north-west and central Highlands could help curb the problem of red deer eating tree saplings, which stops natural woodland regeneration.
