The ecologist, Carwyn Graves discusses our landscape, how we have formed it and how we might continue to do so, in conversation with Welsh presenter and producer Meinir Howells. Graves gives a tour of the Welsh landscape, from the ffridd (mountain pasture) to the rhos (wild moorland). He dives deep into their history and ecology in his book Tir (‘Land’) offering hope for a future with richly biodiverse landscapes, still full of humans working the land.
