Oak woods are dominated by both sessile and pedunculate oak trees. Birch, holly, rowan and hazel are among the other trees commonly found in this woodland habitat. Wildflowers such as bluebells and wood anemones carpet the woodland in spring, before the tree canopy shuts out the light. These woods provide a rich habitat for invertebrates, birds and mammals, along with an amazing array of fungi, mosses and lichens. Oak woodland was the top vegetation in many areas of Britain before their mass clearance by man. Those that are left were managed until around a hundred years ago.

SwallowtailAncient woodland is a term used in the United Kingdom to refer specifically to woodland that has existed continuously since 1600 or before in England and Wales (or 1750 in Scotland). Before those dates, planting of new woodland was uncommon, so a wood present in 1600 was likely to have developed naturally. The analogous American term is "old growth forest".
For many species of animal and plant, ancient woodland sites provide the sole habitat, and for many others, conditions on these sites are much more suitable than those on other sites. Ancient woodland in the UK, like rainforest in the tropics, is home to rare and threatened species, more than any other UK habitat. For these reasons ancient woodland is often described as an irreplaceable resource, or 'critical natural capital'.
Ancient woodland is formally defined on maps by Natural England and equivalent bodies. Many ancient woodlands have legal protection of various types, but it is not automatically the case that any ancient woodland is protected.
