They have been introduced to Britain and Ireland. A large invasive species population of barking deer exists in the United Kingdom. Reeves's muntjac has been introduced to the United Kingdom, with wild deer descended from escapees from the Woburn Abbey estate around 1925. Muntjac have expanded very rapidly, and are now present in most English counties and have also expanded their range into Wales, although they are less common in
