Products of Wall Cladding Stones
"Stone walls, wildlife, and the natural landscape go together. Unlike other forms of "fencing," stone walls lend a sense of harmony to the land. As such structures "age," lichens and mosses decorate the stone in a mosaic of subtle greens and grays. Vines climb over the wall, anchoring their tendrils in the multitude of interstices. Trees and shrubs invade, the wall's foundation adding vertical dimension to the horizontal traverse. As the wall ages with its succession of plant growth, many birds and animals take up residence amid the rocks and niches of the invading vegetation." (John Vivian, Building Stone Wall 1978)
