Ancient woodland is identified using presence or absence of woods from old maps, information about the wood's name, shape, internal boundaries, location relative to other features, ground survey, and aerial photography.本描述摘自英格兰西部及诺森伯兰的古树林资源清单。通过分析古老地图上树林的存在与否、树林名称、形状、内部边界、相对其他地物的位置、地面测量以及航空摄影等信息，识别出古树林。
