dan, where are we? we are in the cairngorm national park, abernethy forest, owned by the rspb but part of the cairngorm connect partnership. it's absolutely beautiful, can you tell me what cairngorm connect is? it's a partnership between four different land owning organisations and what we are trying to do is restore natural processes, trying to get the forest to go back to its natural tree line, restoring peatlands which will help take carbon dioxide out of the atmosphere and where we have rivers that had been altered, we are making them more natural by restoring them to their natural channels. excuse my ignorance, to my untrained eye this looks pretty natural to me. why would you say it needs to be restored? we have been working here for the last 30 years and if you had come here 30 years ago you probably would not be able to see many young trees at all. it is the largest chunk of caledonian pine forest
