The Keyline Scale of Permanence identifies typical farms elements ordered according to their degree of permanence. Keyline considers these elements when planning the placement of water storage, roads, trees, buildings and fences. On undulating land, a keyline approach involves identifying several features namely ridges and valleys and the natural water courses seeking optimum water storage sites and potential interconnecting channels.
The water lines identified from the land-form subsequent provide optimal locations for the various less permanent elements (roads, trees, buildings and fences) to optimise the natural potential of the landscape.

Famous quotes containing the words scale and/or permanence:
“‘Tis very certain that each man carries in his eye the exact indication of his rank in the immense scale of men, and we are always learning to read it. A complete man should need no auxiliaries to his personal presence.”
—Ralph Waldo Emerson (1803–1882)
“Two principles, according to the Settembrinian cosmogony, were in perpetual conflict for possession of the world: force and justice, tyranny and freedom, superstition and knowledge; the law of permanence and the law of change, of ceaseless fermentation issuing in progress. One might call the first the Asiatic, the second the European principle.”
—Thomas Mann (1875–1955)
