Designed Landscapes
In a tillage field near Ballynacorra in County Cork, something that was once deliberately planted has outlasted its own physical presence.
An oval area, roughly 40 metres from north-east to south-west and 26 metres across, now shows itself only as a cropmark, a faint signal readable from the air when differential soil moisture causes the crops above it to grow at a slightly different rate or colour from those surrounding it. Whatever stood here, a ring of trees most likely, is long gone from the surface.
Ordnance Survey maps across every edition consistently mark this spot as a tree ring, suggesting that for at least part of the nineteenth and twentieth centuries, the planting was still visible on the ground. Tree rings of this kind were often ornamental features of designed landscapes, planted in oval or circular formations as eye-catchers, as shelter belts for a nearby house, or simply as a form of land improvement that also served an aesthetic purpose. That the feature has persisted as a cropmark even after the trees themselves disappeared points to a lasting disturbance of the soil beneath, roots, perhaps, or the accumulated organic matter of a long-established planting. The consistency of its depiction across the historical map record makes clear this was no passing feature of the landscape.
