Professor Iain Stewart presents a landmark five-part series in which he reveals how Scotland's unique and beautiful landscape has been shaped.
For centuries, the beauty and drama of Scotland's landscape has been regarded by most visitors as natural. But in 1950, an eminent ecologist concluded the Highlands had been devastated.
Once it was rich and diverse he said, but humans had destroyed it and in the process created what he described as a wet desert. Professor Iain Stewart discovers how man made the proverbially beautiful Highlands.
