Dartmoor MPs are calling for an 'independent process' to work out the balance between farming and conservation on the moors. This follows what some called 'rewilding by the back door' - Natural England's recent decision not to renew some farmers' Countryside Stewardship agreements on the moor, unless the number of livestock was significantly reduced, to try to improve the condition of some protected areas. The three conservative MPs for the area say that despite a working group being set up last year to achieve consensus, Natural England has gone ahead without talking to either the Commoners Association, the National Park or the Dartmoor Owners Association.
