In England and Wales, roe have experienced a substantial expansion in their range in the latter half of the 20th century and continuing into the 21st century. This increase in population also appears to be affecting woodland ecosystems. At the start of the 20th century, they were almost extinct in Southern England, but since then have hugely expanded their range for no apparent reason and possibly in some cases with human help. In 1884, roe were introduced from Württemberg in Germany into the Thetford Chase area, and these spread to populate most of Norfolk, Suffolk, and substantial parts of Cambridgeshire. In southern England, they started their expansion in Sussex (possibly from enclosed stock in Petworth Park) and from there soon spread into Surrey, Berkshire, Wiltshire, Hampshire, and Dorset, and for the first half of the 20th century, most roe in southern England were to be found in these counties. By the end of the 20th century, they had repopulated much of Southern England and had expanded into Somerset, Devon, Cornwall, Oxfordshire, Gloucestershire, Warwickshire, Lincolnshire, and South Yorkshire, and had even spread into mid-Wales from the Ludlow area where an isolated population had appeared. At the same time, the surviving population in Scotland and the Lake District had pushed further south beyond Yorkshire and Lancashire and into Derbyshire and Humberside.
