Ancient Woodland

A term used in the UK to refer specifically to woodland dating back to 1600 or before in England and Wales (or 1750 in Scotland). Before this, planting of new woodland was uncommon, so a wood present in 1600 was likely to have developed naturally. It is considered the last remaining link with the original wooded landscape, which covered the British Isles after the last Ice Age.

Ancient Woodland at Brading, Isle of Wight

  • Ancient woodland now accounts for only around 2 per cent of the UK’s land use
  • Our version of the ‘rainforest’, ancient woodland is home to more threatened species than any other UK habitat and is irreplaceable
  • Nearly 50 per cent of the ancient woodland that still remained in the 1930s, has since been either lost to agriculture and development, or damaged, mainly by conifer plantation
  • Of the remaining ancient woodland in the UK, 85 per cent has no legal designation
  • Ancient woodland is fragmented; eight out of 10 woods are less than 20 hectares (50 acres) in size and nearly 50 per cent of ancient woods are less than five hectares. Woodland Trust
