The fallow deer was introduced to Britain by the Normans and now exists as both managed park herds and free-ranging forest populations, with welfare considerations spanning traditional venison hunting, road mortality, and the social complexity of herding deer.
Fallow deer welfare in parkland settings depends on appropriate stocking density, access to shade and shelter, and management of disease. Overstocking in traditional deer parks causes nutritional competition and reduced body condition. Culling of surplus animals for venison involves welfare risks if conducted by inexperienced operators. Road mortality is significant where deer parks border major roads. The intelligent social nature of fallow deer means that management decisions affecting group composition create social stress.
