Young Blonde Girl Outside Near The Wooden Fence

On private land in the United Kingdom, it is the landowner's responsibility to fence their livestock in. Conversely, for common land, it is the surrounding landowners' responsibility to fence the common's livestock out.
Five-foot-high (1.5 m) fences (over which many people can see and talk) are increasingly being superseded by six-foot fences giving the impression of complete privacy.
