 In the United Kingdom in recent years, these trees are being recorded by the Ancient Tree Hunt so that a national database can be created.Volunteer groups such as the Wokingham District Veteran Tree Association, the Dorset Greenwood Tree Project and the Ashford Veteran Tree Initiative are crucial to the success of this scheme.Although some initiatives have strict rules on how to measure girth and use GPS devices to document the location of such trees accurately, other schemes rely on members of the public to report large trees.
