Yet the places from which much of our wildlife has been disappearing fastest are almost uninhabited. Two friends of mine once walked for six days across the Cambrian Mountains in mid-Wales, and did not see another human being. Yet there is scarcely any wildlife either. Cross that bleak plateau and you will see plenty of moorgrass, some tormentil and moss, a few crows, perhaps the odd pipit and skylark, but almost nothing else, except sodding sheep. The hills have been grazed to destruction.
The Cambrians are worse than most places, but there's a similar story to be told in almost all the uplands of Britain: Dartmoor, Exmoor, the Black Mountains, the Brecon Beacons, Snowdonia, the Shropshire Hills, the Peak District, the Pennines, the Forest of Bowland, the Dales, the North York moors, the Lake District, the Cheviots, the Southern Uplands and the Highlands. The desertification of our uplands, in common with most of our wildlife losses, has nothing to do with population pressure and everything to do with farming.
