Ancient Woodland Inventory (Scotland)

In response to a 1980 select committee which recommended that ancient woods should be recognised and treated as a separate category, the NCCs compiled the Inventories of Ancient, Long-established and Semi-natural woodlands. A more sophisticated classification was developed for woodlands in Scotland due to the nature of the available historical sources.

IMPORTANT
For Scottish woods, the category Ancient comprises woods recorded as being of semi-natural origin on EITHER the 1750 Roy maps OR the 1st Edition Ordnance Survey maps of 1860. This is due a) to the likelihood of the latter having been omitted from the Roy maps and b) to render the Scottish classification compatible with that for England and Wales.

针对1980年选定的委员会的建议，即应将古树林认定为独立类别并加以特别对待，国家森林委员会（NCCs）编制了古树林、历史悠久林和半自然林清单。鉴于可利用的历史资料的特性，苏格兰的林地分类系统发展得更为复杂。对于苏格兰的林地，古代林地类别包括那些在1750年罗伊地图或1860年第一版测量局地图上记录为半自然起源的林地。这一分类的原因在于：a) 后者可能在罗伊地图上被遗漏，以及b) 使苏格兰的分类系统与英格兰和威尔士的分类系统保持一致。
