Another Cumbrian thing is the high level bogs. A lot got drained. Farmers were paid to dig drainage channels which worked very well. Now they're trying to reinstate them by blocking the outflow with rock piles to slow the flow but not stop it completely. They pile more rocks every so often along the drainage stream to slow flow down, encourage flow out of the stream and reinstates the bog. The potential of these to store carbon is immense, more than the equivalent carbon store than a wood of trees would apparently.
There's a few good rewilding schemes like this and reinstating gravel beds, meandering streams / rivers, etc. Not sure ennerdale rewilding is quite a good as these newer thinking. Even in rewilding terms they're learning quickly. What 20 years ago was the height of environmental thinking is now considered less than ideal and knowledge of these things have moved on a long way from just replanting native trees and reducing grazing animal levels.
