 In 1225, as a result of legislation passed by Henry III, several parks were enclosed and several herds, including those at Chartley and Chillingham in England, and Cadzow in Scotland, were "emparked".There were more than a dozen white Park Cattle herds in Britain in the early 19th century, but most of these were exterminated by the turn of the next century.The Park Cattle registration program in Britain was started in the early 1900s, but by 1946 only the Dynevor, Woburn, Whipsnade, and Cadzow herds survived as domesticated herds; the ancient herds at Vaynol (Faenol) and Chillingham having become semi-feral.
