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. A census of deer populations in 2007 and again in 2011 coordinated by the British Deer Society records the red deer as having continued to expand their range in England and Wales since 2000, with expansion most notable in the Midlands and East Anglia.
