Welsh Black cattle free ranging in the mountains of Wales. It is unlikely that a modern commercial breed would thrive on the tough, wiry mountain grass of the Snowdonia. These hardy black cattle fatten without lush lowland grass and are nimble enough to manage the difficult terrain. The Welsh Black has been bred in Wales for more than 1,000 years. At one time they were used as currency, which led to the tradition of the Welsh Black being commonly described as "Black Gold."
