Miocene in Eurasia. Europe and North Africa The European red deer is found in southwestern Asia (Asia Minor and Caucasus regions), North Africa, and Europe. The red deer is the largest nondomesticated land mammal still existing in Ireland. The Barbary stag (which resembles the western European red deer) is the only member of the deer family represented in Africa, with the population centred in the northwestern region of the continent in the Atlas Mountains. As of the mid-1990s, Morocco, Tunisia, and Algeria were the only African countries known to have red deer. In the Netherlands, a large herd (about 3000 animals counted in late 2012) lives in the Oostvaardersplassen, a nature reserve. Ireland has its own unique subspecies. In France, the population is thriving, having multiplied five-fold in the last half-century, increasing from 30,000 in 1970 to around 160,000 in 2014. The deer has particularly expanded its footprint into forests at higher altitudes than before. In the UK, indigenous populations occur in Scotland, the Lake District, and the south west of England (principally on Exmoor). Not all of these are of entirely pure bloodlines, as some of these populations have been supplemented with deliberate releases of deer from parks, such as Warnham or Woburn Abbey, in an attempt to increase antler sizes and body weights. The University of Edinburgh found that, in Scotland, extensive hybridisation with the closely related sika deer has occurred. Several other populations have originated either with "carted" deer kept for stag hunts being left out at the end of the hunt, escapes from deer farms, or deliberate releases. Carted deer were kept by stag hunts with no wild red deer in the locality and were normally recaptured after the hunt and used again; although the hunts are called "stag hunts", the Norwich Staghounds only hunted hinds (female red deer), and in 1950, at least eight hinds (some of which may have been pregnant) were known to be at large near Kimberley and West Harling; they formed the basis of a new population based in Thetford Forest in Norfolk. Further substantial red deer herds originated from escapes or deliberate releases in the New Forest, the Peak District, Suffolk, Lancashire, Brecon Beacons, and North Yorkshire, as well as many other smaller populations scattered throughout England and Wales, and they are all generally increasing in numbers and range.
