It measures roughly 46 metres north to south and 66 metres east to west, large enough to register clearly on a map but modest enough to be easily overlooked on the ground. Tree-rings and designed plantations of this kind were a fashionable feature of Anglo-Irish estate landscapes, used to frame views, define boundaries, or simply signal that a landowner had the resources and inclination to shape the land around them with a degree of aesthetic intention.

The planting appears on the 1899 to 1903 revision of the six-inch Ordnance Survey map, which means it was already established by the time that survey was carried out, though how much earlier it was laid down is not recorded. The estate itself supported several other tree plantations of irregular shape scattered across the grounds, including a further sub-oval grouping approximately 90 metres to the north-north-west. Taken together, these plantings suggest a considered approach to the landscaping of the property rather than purely functional forestry, with different shaped enclosures placed at intervals across the estate to produce a varied, composed effect across the terrain.
