Reeves's Muntjac has been introduced to England, with wild deer descended from escapees from Woburn Safari Park around 1925. Muntjac have expanded very rapidly, and are now present in most English counties south of the M62 motorway and have also expanded their range into Wales. The British Deer Society coordinated a survey of wild deer in the UK between 2005 and 2007, and they reported that Muntjac deer had noticeably expanded their range since the previous census in 2000. It is anticipated that Muntjac may soon become the most numerous species of deer in England and may have also crossed the border into Scotland with a couple of specimens appearing in Northern Ireland in 2009; they have been spotted in the republic of Ireland in 2010, almost certainly having reached there with some human assistance
