Coed Craig Ruperra is what is known as a Planted Ancient Woodland Site (PAWS). These sites are classified as woods which were originally included on registers as far back as the 1600s, and which have been felled and replanted, usually with conifer, most often as a cash crop. PAWS woodlands usually start out as Ancient Semi-Natural Woodland (ASNW), but their native trees have been replaced, usually by non-native conifers.
