Ancient and Long-established Woodland Inventory 2010Department of Housing, Local Government, and HeritageEnvironment
Ancient woodland refers to those woods that have had a continuous history of cover since before the period when planting and afforestation became common practice (mid‐1600s). These woodlands are important in terms of their biological and cultural value, and may even form links wi
