Woody vegetation is necessary to attract seed-dispersing faunae, and for soil development, thus facilitating further the spread of woody shrubs and trees. In this way wallrows are strikingly similar to North American fencerows, though the obvious difference remains that fencerows are based along a wooden fence or under telegraph lines, and wallrows along a field boundary stone wall.
