What survives of a once-deliberate planting of trees is now legible only from the air, as a faint sub-circular cropmark in a field of pasture, roughly 17 metres north to south and 14 metres east to west. A cropmark of this kind appears when buried or levelled earthworks affect the moisture and nutrients available to overlying grass or crops, causing subtle variations in colour or growth that become visible from altitude, particularly in dry conditions. The feature at Harding Grove was recorded on a Google Earth orthoimage taken in September 2020, and an aerial photograph by the Aerial Survey Ireland unit predates that by nearly two decades, taken in September 2002.

Despite its ghostly appearance from altitude, the origins of this feature are relatively recent in historical terms. The 1840 edition of the Ordnance Survey Ireland six-inch map, one of the most thorough surveys of the Irish landscape ever undertaken, depicts it not as an antiquity but as a tree-plantation of post-1700 date. By the time the more detailed 25-inch edition was produced in 1897, the same feature was recorded specifically as a tree-ring, a term for a formally planted circular or near-circular grove, often associated with designed demesne landscapes of the eighteenth or nineteenth century. Such plantings were sometimes ornamental, marking a view or feature within a landed estate's grounds, and occasionally had a more practical function as shelter belts or enclosures. The trees are now gone, and the earthwork beneath has been levelled, but the outline persists as a cropmark. A curvilinear feature also visible on satellite imagery may represent the course of a former watercourse along the northern side, possibly once part of the enclosing arrangement. The site does not appear on the OSi historic maps as an antiquity and sits roughly 160 metres south-west of a recorded ring-barrow, a type of Bronze Age burial monument defined by a circular bank and ditch.

This is not a place with a visitor path or an interpretive panel. The feature lies in private pastureland, 115 metres north-west of a river course, and the most practical way to examine it is through the publicly available satellite imagery on Google Earth, where the September 2020 orthoimage gives the clearest view of the cropmark outline. Those with an interest in how designed landscapes leave their marks, even after the trees and earthworks are gone, will find it a useful case study in how ordinary fields can carry layers of deliberate human arrangement that formal archaeology sometimes overlooks entirely.
