The farmland landscape of the mountains is a result of centuries-old agricultural practices.
The earliest farmers began the laborious process of clearing the land of its Ice Age Legacy of countless granite boulders. The stones were then built into walls, which served as sturdy field boundaries.
With the use of seaweed as field manure and lime to reduce soil acidity, the area under cultivation spread throughout the lowlands and pushed slowly up hillsides. Gradually the landscape, which we associate with Mourne farmland, became established.
